Lab-Grown Brain-Spinal Cord Model Shows 'Irreversible' Nerve Damage May Be Reversed
The licensed hormone drug significantly boosted axon regrowth in damaged neurons, offering a potential route to restore movement after spinal cord injury.

Human organoids reveal how to reverse “irreversible” nerve damage
Cambridge researchers created miniature brain-and-spinal-cord systems in the lab that can send signals and even trigger tiny muscle contractions. They discovered that human neurons gradually lose their ability to regrow after damage during development — but that ability can potentially be switched back on. The team identified a gene network controlling this process and found that an existing hormone drug dramatically boosted nerve fiber regrowth.
Lab-grown brain-spinal cord model shows 'irreversible' nerve damage may be reversed
Cambridge scientists have grown miniature circuits in the lab that mimic how the brain and spinal cord connect, which underlies human movement. They used this model to show how damage to these connections previously considered "irreversible" could, in fact, be reversible.
Miniature lab grown circuits unlock hidden recovery paths for paralysis
Cambridge scientists have grown miniature circuits in the lab that mimic how the brain and spinal cord connect up, which underlies our movements. They used this model to show how damage to these connections previously considered 'irreversible' could, in fact, be reversible.
Cambridge grew a human brain and spinal cord in the lab, separate but connected. They kept them alive for over a year, until the nerve fibers stopped growing on their own after the damage. It was day 150, roughly halfway through a human pregnancy. That day is the moment when, for any of us, axonal regeneration shuts down. The study was published in Cell Reports, and it says something uncomfortable for medical consensus: that shop can reopen. Yes…
Why do organoids reverse nerve damage?
Reversing “irreversible” nerve damage with organoids Researchers at the University of Cambridge created human organoids to study and potentially reverse nerve damage that had previously been described as “irreversible.” The work centers on using miniature, lab grown models of human tissue to mimic…
Contraceptive Drug May Reverse Spinal Paralysis
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.
