Doctors could soon be able to grow new brain cells, which would help treat people with strokes or other neurological conditions, using just a small blood sample.

Scientists from Heidelberg University Hospital in Germany and the University of Innsbruck in Austria figured out how to reprogram mature human blood cells into neural stem cells. Scientists have reprogrammed stem cells before, but these new cells are the first ones that can continue to multiply and propagate in the lab thanks to specific genetic tweaks, according to research published Thursday in the journal Stem Cell.
