John Sibirtzeff will never meet the man who used his stem cells to heal. He'll never know exactly what his affliction was, and he's OK with that.

A month ago, Sibirtzeff spent five days in Washington D.C. donating bone marrow stem cells that would be used to heal a 69-year-old man living in France.

"I'll never know who the recipient was," he said. "I'll never know if he was American or French, military or non."

When Sibirtzeff, of Littlestown, was in Navy boot camp in 2007, he opted into the C.W. Bill Young Department of Defense Marrow Donor Program. Naval doctors drew a vial of his blood and stored it after identifying his type. In 2011, Sibirtzeff finished his tour of duty, but his name remained on the donor list.

This past January, the program contacted Sibirtzeff requesting that he return for testing, as he was a potential match for a 69-year-old man living in France.

According to the program's website, salutetolife.org, 70 percent of patients are unable to find a match within their families. Sibirtzeff's receiver was among them.

Perched on the end of the scientists green glove, the tiny oblong-shaped object looks like a small jewel. It is in fact artificially-grown human cartilage, developed from human stem cells in the laboratory for the first time.

Cartilage, which protects the bone ends in joints, does not have blood vessels or nerves and does not heal over time if damaged.

Scientists at Columbia University in New York took cells from adult bone marrow and developed them into cartilage as robust as the natural human tissue.

We do have technology. We do understand underlying principles. But we are not ready to go into patients. There is a lot of pre-clinical work that will need to be done to make this happen, said Gordana Vunjak-Novakovic, Professor of Biomedical Engineering at Columbia University, who led the study.

Until now, scientists have made cartilage from young animal cells but the resulting tissue was often weak.

In the new study stem cells were condensed via a process that imitates how the body produces the tissue naturally.

The research team now plans to test the cartilage grown from stem cells to examine its long-term effects.

As a new therapeutic approach, Janus kinases are currently in the limelight of cancer research. The focus of interest is the protein JAK2. By inhibiting this protein one tries to cure chronic bone marrow diseases, such as myelofibrosis and chronic myeloid leukemia (CML).

Loss of JAK2 is advantageous for leukemia cells

Scientists working with Veronika Sexl at the Institute of Pharmacology and Toxicology may initiate a transformation of thought in regard of JAK2 inhibition. To simulate the human disease as accurately as possible, the scientists used a mouse leukemia model. In an experiment, mice received blood cancer cells as well as healthy hematopoietic stem cells in which JAK2 had been removed. "In mice, the absence of JAK2 accelerated the course of leukemia drastically," the scientists concluded.

The loss of JAK2 caused healthy hematopoietic stem cells to disappear in mice. "Leukemic cells, on the other hand, remained entirely unaffected; they do not need JAK2. This led to an imbalance in which the number of leukemia cells was very predominant, and eventually caused the acceleration of leukemia," says Eva Grundschober, one of the lead authors.

"The oncogene BCR-ABL, which was present in mice with leukemia, does not appear to require JAK2 for its activity. However, JAK2 is essential for healthy cells," explains Andrea Hlbl-Kovacic, the other lead author.

JAK2 is important for survival of hematopoietic stem cells

A closer investigation of healthy stem cells supports this hypothesis. In the absence of JAK2, healthy stem cells cannot survive and reproduce blood cells. As the next step, the following question will be raised in Sexl's laboratory: how does JAK2 mediate its life-sustaining effect on healthy stem cells? What portions of the JAK2 protein are required for this purpose and are these affected by current therapies?

One cell's meat is another cell's poison: How the loss of a cell protein favors cancer cells while harming healthy cells

Miami, FL (PRWEB) May 31, 2014

Global Stem Cells Group, its subsidiary Stem Cell Training, Inc. and Bioheart, Inc. have announced plans to conduct a two-day, hands-on intensive stem cell training course at the Servet CordnVida Clinic Sept. 27 and 28 in Santiago, Chile. The Adipose Derived Harvesting, Isolation and Re-integration Training Course, will follow the Global Stem Cells Group First International Symposium on Stem Cells and Regenerative Medicine at the Santiago InterContinental Hotel Sept. 26, 2014.

Global Stem Cells Group and the Servet CordnVida Stem Cell Bank Clinic of Chile are co-organizing the symposium, designed to initiate a dialogue between researchers and practitioners and share the expertise of some of the worlds leading experts on stem cell research and therapies.

Servet CordnVida is a private umbilical cord blood bank that harvests and stores the hematopoietic-rich blood stem cells found in all newborns umbilical cords after birth. The hematopoietic tissue is responsible for the renewal of all components of the blood (hematopoiesis) and has the ability to regenerate bone marrow and restore depressed immune systems.

Umbilical (UCB) stem cells offer a wealth of therapeutic potential because they are up to 10 times more concentrated than bone marrow stem cells. In addition, UCB cells have a generous proliferative capacity with therapeutic potential that is very similar to embryonic stem cells, without the ethical debate associated with embryonic stem cell research and use.

UCB cells are the purest adult stem cells available, coming from newborns who have not been exposed to disease or external damage. Many parents today are utilizing cord banks like Servet CordnVida to store their newborns UCB cells safely for future medicinal use if the need arises.

Global Stem Cells Group and Servet CordnVida represent a growing global community of committed stem cell researchers, practitioners and investors whose enthusiasm is a direct result of the hundreds of diseases and injuries that stem cell therapies are curing every day. Global Stem Cell Groups First International Symposium on Stem Cell Research and Regenerative Medicine will host experts from the U.S., Mexico, Greece, Hong Kong and other regions around the globe who will speak on the future of regenerative medicine and share experiences in their field of specialty. The Global Stem Cells Group is hoping the symposium will open lines of communication and cooperation, explore new and exciting techniques in stem cell therapies, and create an environment of education and learning.

For more information on the symposium and the lineup of guests and speakers already confirmed, visit the First International Stem Cells and Regenerative Medicine website, email bnovas(at)regenestem(dot)com, or call 305-224-1858.

Miami (PRWEB) May 31, 2014

Global Stem Cells Group and the Servet CordnVida Stem Cell Bank Clinic of Chile will be teaming up to organize the First International Symposium on Stem Cells and Regenerative Medicine in Santiago, Chile Sept. 26, 27 and 28. The three-day symposium will be followed by an intensive hands-on training course at the Servet Clinic for medical practitioners interested in learning techniques for harvesting stem cells for in-office medical therapies.

Symposium organizers plan to initiate a dialogue between researchers and practitioners to bridge the gap between bench scienceresearch science that is exclusively conducted in a lab settingand stem cell therapies delivered in the physicians office.

The first-of-its-kind conference will host some of the worlds leading experts on stem cell research and therapies. Servet CordnVida General Manager Mauricio Cortes, Ph.D. says that Santiago is the perfect launching pad for the event, as awareness and increasing demand for stem cell services has swept the South American countrys healthcare market over the past decade.

The use of human stem cells in medical therapies has attracted major scientific and public attention because stem cells are pluripotent, meaning they have the ability to differentiate into all body tissues, Cortes says. Knowing this, the possibilities for regenerating damaged or diseased tissue where no effective treatments existed before opens a new world of possibilities to patients and healthcare providers.

Were very excited to participate in this important conference.

Servet CordnVida is a private umbilical cord blood bank that harvests and stores the hematopoietic-rich blood stem cells found in all newborns umbilical cords after birth. The hematopoietic tissue is responsible for the renewal of all components of the blood (hematopoiesis) and has the ability to regenerate bone marrow and restore depressed immune systems.

Umbilical (UCB) stem cells offer a wealth of therapeutic potential because they are up to 10 times more concentrated than bone marrow stem cells. In addition, UCB cells have a generous proliferative capacity with therapeutic potential that is very similar to embryonic stem cells, without the ethical debate associated with embryonic stem cell research and use.

Perhaps most significant is the fact that UCB cells are the purest adult stem cells available, coming from newborns who have not been exposed to disease or external damage. Many parents today are utilizing cord banks like Servet CordnVida to store their newborns UCB cells safely for future medicinal use if the need arises.

Thanks to advances in stem cell science, we can preserve an infants stem cells at birth and store them safely for his or her future, says CordnVida Director Javier Sez. Hopefully, this symposium will be the first of many like it in the future of regenerative medicine, because the more we discuss what we know about the power of stem cells to heal, the closer we get to sparing our patients from needless suffering when the cure is right before us.

By: Stephanie Guadian EL PASO, Texas - Inaki Arruti is an El Paso boy battling leukemia and a shortage of blood and bone marrow donations from the Hispanic community. I recently shared his story with KFOX 14 viewers.

The story hit home for Janet Chavarria. She is an employee at Western Technical College and Inaki's cousin.

After being inspired by our story to take action, she and the school organized a two-day Be the Match blood and bone marrow drive. Those who agreed to register simply swabbed their cheeks. The DNA will be compared to patients for a possible match.

It's not just Inaki. There are more children out there you know that have this. There are more people that have this. So, if we are not helping out Inaki, there might be someone else. But hopefully, there will be a match, said Janet Chavarria.

According to Be the Match, a national marrow donor program, Hispanics have only a 72 percent chance of finding a donor, compared with 93 percent for white patients. Anita Gonzales is a Be the Match employee working in El Paso.

We are blessed with another country right next to us. But everything they blow into the air. Unfortunately, it comes into El Paso and we breathe it. It's in the particles in the air, the ground that we walk on, the food that we eat. So, anyone can get leukemia. It's not inherited, said Gonzales.

Today -- the most common way of collecting stem cells is done by filtering them from a person's blood. The procedure is considered painless and similar to donating blood. The donation could one day save of the life of someone like Inaki.

Nearly 300 people signed up to be potential matches at the two day blood and bone marrow drive at Western Technical College. If you would like to find out how you can sign up to be a donor, check outbethematch.org

Beverly Hills, California (PRWEB) May 29, 2014

The Beverly Hills Orthopedic Institute is now providing several types of stem cell procedures for healing ligament injuries and meniscal tears of the knee. The stem cell therapies are often able to repair the injuries, provide pain relief and help patients avoid the need for surgery. For more information and scheduling, call (310) 438-5343.

Injuries to the knee may occur from sports injuries, auto accidents or result from degenerative arthritis. Conventional treatments typically work well for pain relief, however, they do not repair the damaged soft tissue. Therefore, conventional treatments result in healing that is incomplete and may still lead to the need for the surgery.

At Beverly Hills Orthopedic Institute, Double Board Certified Los Angeles Orthopedic Surgeon Dr. Raj has been a pioneer in stem cell procedures for the knee. He is an expert in several types of stem cell therapies for knee injuries including amniotic derived or bone marrow derived stem cell injections.

The regenerative medicine procedures are performed as an outpatient and maintain exceptionally low risk. The amniotic-derived stem cell material is processed at an FDA regulated lab, while the bone marrow-derived stem cell therapy involves a short harvesting procedure from the patient himself. Both types of procedures have been shown in small studies to have excellent clinical results for knee conditions.

Along with treating all types of knee injuries with stem cell therapy, Beverly Hills orthopedic surgeon Dr. Raj also treats shoulder, hip ankle and spinal conditions with regenerative medicine as well. Treatments are provided for amateur and professional athletes, weekend warriors, executives, grandparents, students and more.

For those who desire to explore stem cell procedures for helping repair knee injuries and avoiding surgery, call the Beverly Hills Orthopedic Institute at (310) 438-5343.

Janus kinases (JAKs) are proteins that can promote the growth of cancer cells. The protein JAK2 is of special therapeutic significance: its inactivation is believed to destroy cancer cells. However, the effect of JAK2 inhibition on healthy blood stem cells is so far unknown. Scientists at the Vetmeduni Vienna show that the loss of JAK2 in the mouse causes healthy blood stem cells to disappear while cancer cells preserve their growth potential. Future studies will address the question as to whether these data can be passed on to treatment in humans. The results were published in the journal Leukemia. As a new therapeutic approach, Janus kinases are currently in the limelight of cancer research. The focus of interest is the protein JAK2. By inhibiting this protein one tries to cure chronic bone marrow diseases, such as myelofibrosis and chronic myeloid leukemia (CML).

Tampa, Fla. (May 28, 2014) To be suitable for medical transplantation, one idea is that human embryonic stem cells (hESCs) need to remain "undifferentiated" i.e. they are not changing into other cell types. In determining the best way to culture hESCs so that they remain undifferentiated and also grow, proliferate and survive, researchers have used blood cell "feeder-layer" cultures using animal-derived feeder cells, often from mice (mouse embryonic fibroblasts [MEFs]). This approach has, however, been associated with a variety of contamination problems, including pathogen and viral transmission.

To avoid contamination problems, a Brazilian research team has investigated the use of human menstrual blood-derived mesenchymal cells (MBMCs) as feeder layers and found that "MBMCs can replace animal-derived feeder systems in human embryonic stem cell culture systems and support their growth in an undifferentiated stage."

The study will be published in a future issue of Cell Medicine, but is currently freely available on-line as an unedited early e-pub at: http://www.ingentaconnect.com/content/cog/cm/pre-prints/content-CM1019silvadosSantos.

"Human embryonic stem cells present a continuous proliferation in an undifferentiated state, resulting in an unlimited amount of cells with the potential to differentiate toward any type of cell in the human body," said study corresponding author Dr. Regina Coeli dos Santos Goldenberg of the Instituto de Biofisica Carlos Chagas Filho, Universidade Federal do Rio de Janeiro. "These characteristics make hESCs good candidates for cell based therapies."

Feeder-layers for hESCs comprised of MEFs have been efficiently used for decades but, because of the clinical drawbacks, the authors subsequently experimented with human menstrual blood cells as a potential replacement for animal-derived feeder-layers, not only for negating the contamination issues, but also because human menstrual blood is so accessible. MBMCs are without ethical encumbrances and shortages, nor are they difficult to access - a problem with other human cells, such as umbilical cord blood cells, adult bone marrow cells or placenta cells.

"Menstrual blood is derived from uterine tissues," explained the researchers. "These cells are widely available 12 times a year from women of child-bearing age. The cells are easily obtained, possess the capability of long-term proliferation and are clinically compatible with hESCs-derived cells."

The researchers found that their culture system using MBMCs as a feeder-layer for hESCs are the "closest and more suitable alternative to animal-free conditions for growing hESCs" and a "good candidate for large-expansion of cells for clinical application." They also found no difference in growth factor expression when comparing the use of growth factors in both the standard feeder system using animal cells and the feeder system they tested using hESCs.

Discredited stem-cell treatment loses in Strasbourg

(ANSA) - Strasbourg, May 28 - The European Court of Human Rights on Wednesday ruled that an Italian ban on a controversial stem-cell therapy was legitimate. The case centered around a woman suffering from a degenerative brain disease since birth who argued her rights had been violated by the State denying her Stamina treatment. The process involves extracting bone-marrow stem cells from a patient, turning them into neurons by exposing them to retinoic acid for two hours, and injecting them back into the patient. But its credibility has long been suspect, and last fall the health ministry ruled that the Stamina Foundation would no longer be allowed to test the treatment on humans. The foundation was also stripped of its non-profit status after a study found its treatment was "ignorant of stem-cell biology". Recent investigations have shown risks of the treatment range from nausea to cancer, and as many as one quarter of all patients treated have experienced "adverse effects". The head of the foundation, Davide Vannoni, may face indictment.

A new Israeli company is using the natural process of cell death to help people undergoing transplants of all kinds live longer. This counterintuitive approach is the vision of Cellect and could radically change the way people with leukemia manage their disease.

Stem cells hold the promise to eradicate cancer and other devastating diseases. But one of the biggest bottlenecks for clinicians and researchers is getting enough stem cells in a blood sample to use in transplantation.

If too many of the donors regular body cells are left in the sample, a patient undergoing a bone-marrow transplant will probably suffer an immune reaction, which can be deadly. In fact, about half of all bone-marrow transplants lead to graft vs. host disease, requiring a lifetime of immunosuppressant drugs.

A new approach to harvesting stem cells is required, says Dr. Shai Yarkoni, a medical doctor, biomed expert and co-founder and CEO of Cellect.

Stem cells are defined not by how they look but what they can do. So my partner, Dr. Nadir Askenasy also a physician, a chemist and a genius came up with an intuitive approach for how we should select them from a sample for transplantation, says Yarkoni in an interview with ISRAEL21c.

Off-the-shelf, cheaper, faster

Several companies, such Miltenyi Biotec in Germany, make tools to cull stem cells from donor blood. But the process is expensive, about $50,000 per transplant, and requires three days of work by skilled personnel. Worse, the current technology still leaves a significant amount of body cells behind or alternatively, too few stem cells.

Thousands of companies and millions of researchers know what they can do with stem cells, but the raw material is the critical issue, Yarkoni says. How do you get enough stem cells to start the treatment?

Cellects stem-cell selection kit, a unique medical device originally conceived by Askenasy about a decade ago, could accomplish the task more effectively, and for a fraction of the cost.

The only tool thats needed is a biological hood, and these can be found even in developing countries. The process takes less than 10 hours and its simple to do, based on the natural process of cell death (apoptosis).

DALLAS Hispanics, African Americans and Asians have a more difficult time of getting a bone marrow transplant because the national database of potential donors doesnt include many minorities.

But, an effort is underway over the Memorial Day weekend to increase the number of minority donors.

Jose Barrera is among the thousands suffering from a blood cancer specifically Chronic Myeloid Leukemia but he never showed a symptom of it.

"Your body flushes out the white blood cells in your body," Barrera explained. "But with me, the dead ones were just staying in my blood stream and they were overcrowding and that's when you develop cancerous cells."

Barrera, 22, works weekends at Sherlock's Baker Street Pub on Park Lane and studies accounting at the University of North Texas.

Doctors discovered his CML during a routine eye exam at Wal-Mart last September. Fortunately, he said, its the most curable.

The rest is here:
Critical need for Hispanic, minority bone marrow donors

Mike Brandon was given just 60 days to find a bone marrow transplant. If he didn't, his leukaemia - cancer of white blood cells - was going to overwhelm his body.

Most people faced with such odds may have given up, but Brandon's fiance, Kate Robertson launched a desperate bid to find a matching donor for her husband-to-be.

The odds paid off: less than a month after Miss Robertson's campaign was launched, a donor has been found.

Anthony Nolan said that her efforts has led to a 650% increase in people joining the bone marrow register. The blood cancer charity said that there was a particular surge among potential donors in the couple's home city of Bristol.

Miss Robertson, 31, said the response has been "astounding".

"It's been an incredibly difficult time so the relief we're feeling is overwhelming," she said.

"A matching donor means that we can go ahead with Mike's bone marrow transplant. We know we have a rocky road ahead as a transplant is a serious procedure, but knowing there is a good match for Mike is a fantastic boost that we desperately needed.

"We are hugely grateful to the selfless person who has stepped forward to help Mike, and to everyone who has pledged to do the same for someone else, by joining the Anthony Nolan register."

Bride Saves The Life Of Her Fianc Who Had Only 60 Days To Live By Finding A Stem Cell Donor

The seemingly miraculous recovery of little Hannah Day who rebounded earlier this month after a rare bone marrow transplant cancer free for 60 days has suffered a major setback.

Mother Brooke Ervin said her stem cells, which were transplanted into her daughter on March 19, are attacking her four-year-old daughters body from the inside out, manifesting in a rash and third-degree-like burns.

She has burns to 90 per cent of her body and is now admitted back to [B.C. Childrens] hospital in hopes they can stop it.

Hannah is in immeasurable pain as her family watches, terrified and helpless, Ervin said Wednesday.

Hannah is not responding to oral antibiotics, and steroids being pumped into her body to stop the burning are suppressing her immune system, which is needed to fight off the cancer.

This is such a horrible life she got, a distraught Ervin said.

She has spent most of her life suffering just to stay alive. No one should have to fight so hard, especially an innocent child.

She wants to live so bad and she shows us every day with her fight and will to live, Ervin said. She wont give up and we cant either. We have to hold strong in the hopes one day this will end.

On May 6, Hannah was discharged from hospital in Vancouver after receiving stem cells from her mother in a haploidentical transplant.

Although only a half match, doctors hope Hannahs cells will recognize her moms cells which once protected her in the womb and allow them to kill off cancer cells in Hannahs body.

Its an image Angie Lawn said shed never forget.

It was May of 2013, and she was at her 19-year-old sons funeral. PJ had just died after complications related to leukemia. The day was a blur, and she was distraught as she walked out of the service and into the parking lot.

On the periphery of the crowd at the edge of the parking lot was this long line of La Salle boys all standing with their jackets, very respectfully, with their hands folded, she recalled. They were some of the last to leave.

A year later, Angie and her family, who live in Wyndmoor, near La Salle College High Schools campus, are organizing a bone marrow donor drive at Springfield Township High School May 31 in honor of PJ.

Angie described her son as a brainiac who loved writing and computer science. He found pleasure in comic books, movies, TV shows, games like Monopoly and a good cheesesteak, she said. He played guitar and piano, and he was skilled at doing imitations and making people laugh.

He took very little for granted, partly because of the cancer, but partly because thats just who he was, she said.

PJ was 12 years old when he was first diagnosed with leukemia, a cancer of the blood cells.

Angie remembered they were going to get ice cream, and PJ didnt want any because he said his chin was bothering him. To be cautious, they went to the doctor, and a blood test determined it was acute lymphoblastic leukemia.

At that point, PJ was just about to head to St. Genevieves for the seventh grade, but instead he was tutored at CHOP as an inpatient that year. The doctors decided to try a bone marrow transplant, but neither Angie nor her husband, Patrick, were a match for PJ. Siblings have a slightly better chance at being a match, so the Lawns other children were tested: Shannon, a senior now at Springfield Township High School; Sean, a sophomore at the high school; and Owen, a seventh-grader at St. Genevieves currently.

Shannon was 10 years old when she was determined to be a match for her older brother. Continued...

ALAMEDA -- Ten-year-old Myla Cunanan, a fourth-grader at Ruby Bridges Elementary School in Alameda, has been in Kaiser Oakland since March 24, undergoing her second round of chemotherapy for myeloid sarcoma, a form of acute myeloid leukemia.

Ruby Bridges Elementary hosted a "Myla Needs a Match" bone marrow donor registration drive Saturday that was attended by school parents, Myla's classmates, Kaiser Oakland staff, volunteers from the Asian-American Donor Program (AADP), congregants from the Church of Christ in Alameda, which Myla's family attends, the Alameda Police Department and many others. By day's end, 97 adults had registered to donate bone marrow.

"She's in good spirits; she's very brave," said Myla's mother, Leyna Cunanan, whose daughter was diagnosed with the disease in March. "She needs a bone-marrow transplant in order to survive."

Myla's cousin, 13-year-old Kaitlyn Francisco, who attends Lincoln Middle School, welcomed visitors as they arrived at the bone marrow drive.

"I want to work hard in order for my cousin to get better," Kaitlyn said. "Myla is very sweet, funny and considerate. We visit her every Sunday. Sometimes she's very cheerful, and sometimes she's weak and tired. When we visit her, she always tries to be active."

Myla's sister, Marielle, 13, and her brother, Matthew, 15, also welcomed visitors to the bone marrow drive, standing outside the school where dozens of purple balloons danced in the wind.

"She's really playful and talkative," said Marielle of her little sister. "I want to help find a match for my sister so she can heal."

Myla's aunt, Sarlea Atizado, described her niece as "a very sweet, caring and God-fearing child."

"She has a strong faith in God and does so many selfless acts," Atizado said. "Even in times of sickness, she worries about other people, especially her loved ones. One of her prayers was, 'God, please heal me so that my loved ones will not worry about me, especially my grandmother.' Myla has not only given us the opportunity to take care and pray for her, but has made our family even stronger despite this ordeal. God has a purpose for everything."

Myla is of Filipino descent, which makes it more difficult to find a bone marrow match, according to AADP volunteer Jaydeep Pathak, who explained bone marrow donation procedures to potential donors at the event.

Hip surgery conducted with a 3D printed titanium implant and bone stem cell graft has been conducted in Southampton.

The 3D printed hip was designed using the patients CT scan and CAD CAM file, thereby matching the patients exact specifications and measurements.

According to Southampton University, the implant will provide a new socket for the ball of the femur bone to enter. Doctors have also inserted a graft containing bone stem cells behind the implant and between the pelvis .

The graft is said to acts as a filler for the loss of bone, with the patients own bone marrow cells added to the graft to provide a source of bone stem cells to encourage bone regeneration behind and around the implant.

The benefits to the patient through this pioneering procedure are numerous, said Douglas Dunlop, consultant orthopaedic surgeon who conducted the operation at Southampton General Hospital. The titanium used to make the hip is more durable and has been printed to match the patients exact measurements this should improve fit and could recue the risk of having to have another surgery. The bone graft material that has been used has excellent biocompatibility and strength and will fill the defect behind the bone well, fusing it all together.

Over the past decade Dunlop and Prof Richard Oreffo, at Southampton University, have developed a translational research programme to drive bone formation using patient skeletal stem cells in orthopaedics.

The graft used in the operation is made up of a bone scaffold that allows blood to flow through it. Stem cells from the bone marrow will attach to the material and grow new bone, which will support the 3D printed hip implant.

In a statement, Prof Oreffo said: The 3D printing of the implant in titanium, from CT scans of the patient and stem cell graft is cutting edge and offers the possibility of improved outcomes for patients.

Fractures and bone loss due to trauma or disease are a significant clinical and socioeconomic problem. Growing bone at the point of injury alongside a hip implant that has been designed to the exact fit of the patient is exciting and offers real opportunities for improved recovery and quality of life.

Patient receives 3D printed titanium hip

Doctors and scientists in Southampton have completed their first hip surgery with a 3D printed implant and bone stem cell graft.

The 3D printed hip, made from titanium, was designed using the patient's CT scan and CAD CAM (computer aided design and computer aided manufacturing) technology, meaning it was designed to the patient's exact specifications and measurements.

The implant will provide a new socket for the ball of the femur bone to enter. Behind the implant and between the pelvis, doctors have inserted a graft containing bone stem cells.

The graft acts as a filler for the loss of bone. The patient's own bone marrow cells have been added to the graft to provide a source of bone stem cells to encourage bone regeneration behind and around the implant.

Southampton doctors believe this is a game changer. Douglas Dunlop, Consultant Orthopaedic Surgeon, conducted the operation at Southampton General Hospital. He says: "The benefits to the patient through this pioneering procedure are numerous. The titanium used to make the hip is more durable and has been printed to match the patient's exact measurements -- this should improve fit and could recue the risk of having to have another surgery.

Ground breaking hip and stem cell surgery completed using 3D-printed implant

On his journey from Birmingham boy to Hollywood star David Harewood has shared the silver screen with Leonardo Di Caprio and earned an MBE for services to drama.

But the Homeland actor says his finest moment came away from the cameras and the red carpet.

Seven years ago David received a telephone call from the Anthony Nolan Trust. Someone somewhere had the blood cancer leukaemia and was in desperate need of a bone marrow transplant to help them beat the disease.

David was the closest match.

David, 48, says: The call came completely out of the blue, I felt like I had won the lottery. It was like a giant finger in the sky pointing me out and saying, its you. I immediately wanted to do whatever I could to help.

The transplant was initially scheduled for a few months later, but those plans had to be hastily revised while RADA-trained actor David was in Romania filming The Last Enemy for BBC One.

I had another call to say my recipient had taken a turn for the worse, says David, who is best known for playing CIA counter-terrorism chief David Este in the hit US spy drama Homeland.

They couldnt wait until I finished filming as they might not make it. They needed my stem cells urgently, it was horrifying.

Thankfully David was due a break in filming, which he used to flew straight home to the UK. A nurse then visited him at home every morning for four days, giving him injections to boost his stem cell production.

On the fifth day David went to Harley Street in London to have his stem cells harvested. He was hooked up to a machine that took blood from one arm, filtered out the vital stems cells that would replace his recipients bone marrow and fed the blood back into his body through a needle in the other arm.

First ever hip surgery with 3D printed implant and bone stem cell graft conducted

Washington, May 18 : Harvard Stem Cell Institute (HSCI) scientists at Massachusetts General Hospital have found a potential solution for how to more effectively kill tumor cells using cancer-killing viruses.

The investigators report that trapping virus-loaded stem cells in a gel and applying them to tumors significantly improved survival in mice with glioblastoma multiforme, the most common brain tumor in human adults and also the most difficult to treat.

The work was led by Khalid Shah, MS, PhD, an HSCI Principal Faculty member. Shah heads the Molecular Neurotherapy and Imaging Laboratory at Massachusetts General Hospital.

Cancer-killing or oncolytic viruses have been used in numerous phase 1 and 2 clinical trials for brain tumors but with limited success. In preclinical studies, oncolytic herpes simplex viruses seemed especially promising, as they naturally infect dividing brain cells.

However, the therapy hasn't translated as well for human patients. The problem previous researchers couldn't overcome was how to keep the herpes viruses at the tumor site long enough to work.

Shah and his team turned to mesenchymal stem cells (MSCs)-a type of stem cell that gives rise to bone marrow tissue-which have been very attractive drug delivery vehicles because they trigger a minimal immune response and can be utilized to carry oncolytic viruses.

Shah and his team loaded the herpes virus into human MSCs and injected the cells into glioblastoma tumors developed in mice.

Using multiple imaging markers, it was possible to watch the virus as it passed from the stem cells to the first layer of brain tumor cells and subsequently into all of the tumor cells.

Using imaging proteins to watch in real time how the virus combated the cancer, Shah's team noticed that the gel kept the stem cells alive longer, which allowed the virus to replicate and kill any residual cancer cells that were not cut out during the debulking surgery. This translated into a higher survival rate for mice that received the gel-encapsulated stem cells.

Dr. Broyles' Cartilage Regeneration: Why Bone Marrow Stem Cells? - Video

THURSDAY, May 15, 2014 (HealthDay News) -- Although the very concept of cancer stem cells has been controversial, new research provides proof that these distinct types of cells exist in humans.

Using genetic tracking, researchers found that a gene mutation tied to cancer's development can be traced back to cancer stem cells. These cells are at the root of cancer and responsible for supporting the growth and progression of the disease, the scientists report.

Cancer stem cells are able to replenish themselves and produce other types of cancer cells, just as healthy cells produce other normal cells, the study's British and European authors explained.

"It's like having dandelions in your lawn. You can pull out as many as you want, but if you don't get the roots they'll come back," study first author Dr. Petter Woll, of the MRC Weatherall Institute for Molecular Medicine at the University of Oxford, said in a university news release.

The researchers, led by a team of scientists at Oxford and the Karolinska Institute in Sweden, said their findings could have significant implications for cancer treatment. They explained that by targeting cancer stem cells, doctors could not only get rid of a patient's cancer but also prevent any remaining cancer cells from sustaining the disease.

The study, published May 15 in Cancer Cell, involved 15 patients diagnosed with myelodysplastic syndromes (MDS), a type of cancer that often develops into acute myeloid leukemia, a form of blood cancer.

The researchers examined the cancer cells in the patients' bone marrow. Four of the patients were also monitored over time. One patient was followed for two years. Two patients were followed for 30 months and another patient was monitored for 10 years.

According to the researchers, in prior studies citing the existence of cancer stem cells, the lab tests that were used to identify these cells were considered by many to be unreliable.

However, "In our studies we avoided the problem of unreliable lab tests by tracking the origin and development of cancer-driving mutations in MDS patients," explained study leader Sten Eirik Jacobsen, of Oxford's MRC Molecular Haematology Unit and the Weatherall Institute for Molecular Medicine.

According to the research, a distinct group of MDS cells had all the characteristics of cancer stem cells, and only these particular cancer cells appeared able to cause tumor spread.
