"The research group, at the Stanford University School of Medicine in California, is looking at another option - converting a person’s own skin cells into specialist cells, without creating "induced" stem cells. It has already transformed skin cells directly into neurons.
This study created “neural precursor” cells, which can develop into three types of brain cell: neurons, astrocytes and oligodendrocytes.
These precursor cells have the advantage that, once created, they can be grown in a laboratory into very large numbers. This could be critical if the cells were to be used in any therapy.”
