A new study leverages 3D stem cell organoids to prove that previously "irreversible" central nervous system damage can, in fact, be reversed. By growing interconnected "mini-brains" and spinal cords in a dish for over a year, researchers isolated a distinct genetic network that serves as an absolute maturity switch, permanently halting axon regrowth around day 150 of fetal development.
