This photo shows a lab-grown brain-spinal cord model, which scientists at Cambridge University have used to prove that damage to nerve connections can be reversed with the help of the contraceptive drug, Lynestrenol.
Using this drug when applied to damage to mature models, it significantly boosted axon regrowth. They also discovered that damage axons grow effortlessly until the third trimester of human pregnancy.
Scientists were able to trick mature human neurons into reverting to an embryonic state by by a chemically blocking genetic expressions, and made them regrow.
A new study leverages 3D stem cell organoids and lynestrenol to reverse permanent spinal cord paralysis.
