Placental Senescence

Part of the Advances in Experimental Medicine and Biology book series (AEMB, volume 176)


There are no universally accepted definitions of inherent biologic aging. Consequently, it is currently impossible to state whether or not the placenta fits any such definition, i.e. ages. The question is further complicated by the possibility that the placenta does, in fact, age but has not reached readily recognizable old age by the end of its normal life span. The only analysis currently possible is to observe those things which are associated with aging in individuals and to see if they occur in the placenta.
