Stem cell biologists discover how to regenerate type damaged in ALS, spinal cord injuries Harvard stem cell biologists have discovered a way to grow the type of brain cells that degenerate in patients with amyotrophic lateral sclerosis (ALS) and suffer damage in spinal cord injuries.

A new study explores how extracellular vesicles from embryonic stem cells can protect other cells from oxidative stress, potentially slowing the aging process Senescence.
