Aging is a major risk factor for many human diseases, and in vitro generation of human neurons is an attractive approach for modeling aging-related brain disorders.  While aggressive familial early onset versions of fatal neurodegenerative diseases like Alzheimer’s or Parkinson’s disease can emerge in mid-life, the overwhelming majority of cases develop sporadically in old age, without known genetic causes. Neurons are a prime target for … Continue reading New technique enables researchers to grow old human brain cells for the first time.
