RESEARCHERS are aiming to develop new therapies for osteoarthritis by rejuvenating old stem cells to repair cartilage damage.

A research team at York University have been awarded 190,158 from the medical research charity Arthritis Research UK to carry out a three-year study to investigate how rejuvenated cells from older people with osteoarthritis can be used to repair worn or damaged cartilage, reducing chronic pain.

There is currently no treatment to prevent the progression of osteoarthritis, and people with severe disease often need total joint replacement surgery.

A patients own bone marrow stem cells are a valuable source of potential treatment as they can generate joint tissue that wont be rejected when re-implanted. However, as people grow older the number of stem cells decreases and those that remain are less able to grow and repair tissue.

Dr Paul Genever, lead researcher, who heads up the Arthritis Research UK Tissue Engineering Centre at the University of York said: A way to reset stem cells to an earlier time point, termed rejuvenation, has recently been discovered, allowing more effective tissue repair.

This project will firstly compare rejuvenated and non-rejuvenated stem cells to see if the process improves cartilage repair, and secondly, investigate whether it is possible to develop new drugs which are able to rejuvenate stem cells.

In the UK, more than 8m people, have sought treatment from their GP for the condition, which causes pain and stiffness in the joints due to cartilage at the ends of bones wearing away.

Professor Alan Silman, medical director at charity Arthritis Research UK, said: This is pioneering research, which has the potential to help reduce pain and disability and improving quality of life of those living with osteoarthritis.
