marmosetA New World monkey of South and Central America. With a lifespan of 5 to 7 years and a maximum lifespan of 16½ years, marmosets are the shortest-lived anthropoid primates. They display age-related pathologies that mirror those of humans, such as cancer, amyloidosis, diabetes and chronic renal disease, and have predictable age-related differences in lean mass, calf circumference, albumin, haemoglobin and hematocrit. Features of spontaneous sensory and neurodegenerative change (e.g., reduced neurogenesis, beta-amyloid deposition in the cerebral cortex, loss of calbindin D28k binding and presbycusis) appear between age 7 and 10.
