This method opens the doors to producing all sorts of hard-to-access cells and tissues so we can better our understanding of diseases and the response of these tissues to newly developed therapeutics. - Mark Kotter

The results published in Stem Cell Reports open the door to producing a diversity of new cell types that could not be made before in order to study disease.

Human pluripotent stem cells are master cells that have the ability to develop into almost any type of tissue, including brain cells. They hold huge potential for studying human development and the impact of diseases, including cancer, Alzheimers, multiple sclerosis, and heart disease.

In a human, it takes nine to twelve months for a single brain cell to develop fully. It can take between three and 20 weeks using current methods to create human brain cells, including grey matter (neurons) and white matter (oligodendrocytes) from an induced pluripotent stem cell that is, a stem cell generated by reprogramming a skin cell to its master stage. However, these methods are complex and time-consuming, often producing a mixed population of cells.

The new platform technology, OPTi-OX, optimises the way of switching on genes in human stem cells. Scientists applied OPTi-OX to the production of millions of nearly identical cells in a matter of days. In addition to the neurons, oligodendrocytes, and muscle cells the scientists created in the study, OPTi-OX holds the possibility of generating any cell type at unprecedented purities, in this short timeframe.
