Conclu sion:(1)Surface densities of PCNApositive cells reached their peaks on 14th day after birth,but the number of apoptotic cells reached its peaks on 21st day p ostnatal,so the apoptotic peak was late the proliferating peak for a week,and related to the particular period in cycle of seminiferous epithelium;(2)The spe rmatogium were found move from center to the periphery of the seminiferous tubule and arrange disorder to order;(3)The spermatogonium remained replicating activ ity of DNA during the developing stage.
