Accumulation of cardiac lipofuscin in crab-eating monkeys (Macaca fasicularis): the same rate of lipofuscin accumulation in several species of primates.
Previously, we have reported that the aging process begins at sexual maturation (Nakano, M. et al., Mech. Ageing Dev., 52 (1990) 93-106). In this paper, we reported the cardiac lipofuscin accumulation of crab-eating monkeys. The first appearance of cardiac lipofuscin was around sexual maturation, and the rate of accumulation in crab-eating monkey was 0.45. Several primates which have different life spans show the same rate of lipofuscin accumulation in the life stage. Namely, even in a different life span, the amount of lipofuscin accumulation in a given period of life such as puberty, middle age, old age was the same. From these results, it is suggested that the amount of lipofuscin accumulation is the same in the life span of primates having different life spans.
