Neural stem cells raised from the blood can revolutionize medicine

Doctors could soon work on new brain cells, which would help treat people with strokes or other neurological conditions, using only a small blood sample.

Scientists from Heidelberg University Hospital in Germany and the University of Innsbruck, Austria, figured out how to reprogram mature blood cells into neural stem cells. Scientists have previously reprogramed stem cells, but these new cells are the first to continue to multiply and propagate in the laboratory thanks to specific genetic changes, according to a study published on Thursday in the journal Stem Cell.

Scientists hope their findings will improve regenerative medicine, the type of treatment in which new cells help rejuvenate the body. In particular, neuronal stem cells can develop into neurons located in the central nervous system or the glial cells that support and protect these neurons. Both could help treat those who survived strokes or were diagnosed with neurological disorders.

Previous research that reprogramed cells into stem cells has never been useful in the medical context, since these cells can not continue to multiply, and sometimes tumors are called teratomas, according to research.
