Aged neurons can now be generated using stem cell technology
Washington DC (SPX) Oct 12, 2015
Diseases of human aging have always been difficult to study in the lab. Stem cell technology always had promise, but when scientists reverted a skin cell from an 89-year-old woman back into a stem cell-like state, the cells became young again. Now, a new approach, presented October 8 in Cell Stem Cell, makes it possible to generate and grow cultures of neurons with gene expression reflecting a patient's age. These aged neurons are ideal for studying the differences between the old and young brain. ... read more
