Studies Suggest Mammalian Regeneration Capacity Is Dormant, Not Lost
Original: The Off Switch: Mammals May Have Been Hiding the Power to Regrow Themselves All Along
Short summary
Two research teams found that mammals may retain dormant regenerative capabilities. A Beijing team reactivated the ALDH1A2 gene switch in mice, enabling ear tissue regeneration, while a Texas A&M team used FGF2 and BMP2 signaling proteins to regrow digit bone and joints. Both studies suggest regeneration was switched off, not lost, potentially reshaping regenerative medicine R&D.
- •Mammalian regeneration may be dormant, not lost — genetic switches can be reactivated
- •Beijing team restored retinoic acid pathway; Texas A&M used FGF2/BMP2 protein sequence
- •FGF2 and BMP2 are already FDA-approved or in trials, shortening the path to clinic
