Brain cells made from urine

Brain cells made from urine.

Human excreta could be a powerful source of cells to study disease, bypassing some of the problems of using stem cells.

Some of the waste that humans flush away every day could become a powerful source of brain cells to study disease, and may even one day be used in therapies for neurodegenerative diseases. Scientists have found a relatively straightforward way to persuade the cells discarded in human urine to turn into valuable neurons.
