Genetic switch enables tissue regeneration in mammals, Chinese research shows
Originally Published 6 months ago — by Phys.org
Researchers have discovered that activating a dormant gene, Aldh1a2, in mice can restore their ability to regenerate ear tissue, including cartilage and nerves, by increasing retinoic acid production. This finding suggests potential pathways to enhance regenerative medicine in mammals by reactivating ancient genetic mechanisms that have been silenced over evolution.
