Study in mice reveals that adult tissues retain a memory of which genes are activated during very early development, and that that memory can be recovered. Under certain conditions, adult cells play their developmental “movie” in a slow rewind, reactivating fetal genes. These findings have important implications for regenerative medicine and cancer research.

By exposing stem cell-derived kidney organoids to fluidic shear stress, A team of Harvard researchers has significantly expanded the organoids’ vascular networks and improved the maturation of kidney compartments.

Scientists at the Harvard Stem Cell Institute are seeking ways to protect newly transplanted cells from autoimmune attack.
