Lab-Grown Brains Could One Day Help Reawaken Nerve Regeneration
- Cambridge researchers show lab-grown brain–spinal cord models can regrow axons for over a year, hinting at reversible regenerative limits.
- Blocking a network of genes restored some axon regrowth, suggesting targets for promoting regeneration in human neurons.
- Lynestrenol, an approved contraceptive, boosted axon regrowth in the lab models, offering a possible therapeutic lead.
- Researchers emphasize the need to show this approach improves meaningful connections between brain and spinal cord before clinical use.
- The study builds on prior work with lab-grown 'mini-brains' to study human nerve regeneration in a controlled setting.
- The study appeared in Cell Reports and examined human corticospinal organoid models that connect brain and spinal cord components.
- Researchers linked gene networks to regenerative capacity and identified factors limiting axon growth as neurons mature.
- The work used organoid models to bridge differences between animal and human neuron behavior.
- The article notes the research is for informational purposes only and not medical advice.
- The team observed gene networks governing neuron–cell connections that, when targeted, influenced regeneration.
