Selective aging in Acomys cahirinus: linking regenerative biology to healthy aging mechanisms
This project argues that the Cairo spiny mouse, Acomys cahirinus, may be a useful mammalian model for healthy aging because older animals reportedly retain spatial memory and motor learning better than conventional lab mice while also showing unusual regenerative traits. The strongest support in the evidence is still mixed: the core project record is an internal, prospective description rather than a peer-reviewed outcome, and published field-context studies suggest both resilience signals and important caveats, including delayed and spatially heterogeneous wound regeneration in older animals.
