Aging Mouse Monitoring Platform

rotor test.jpg

The fratily index (FI) used to monitor the phenotypes of aging mice was established by Susan E Howlett's group in 2014 (PMID: 24051346). Global phenotypes, including integument, physical/ musculoskeletal, vestibulocochlear/ auditory, ocular/ nasal, Digestive/urogenital, eespiratory, discomfort, temperature, and bodyweight are considered. The FI has been used as the major score for the aging mice in several high-impact papers, including Nat Aging, Nat Med, Nat Com, et al.

​

  1. A clinical frailty index in aging mice relative to young mice

  2. Physical activity in aging mice
