本文用放射自显影技术研究了大鼠生后发育过程中附睾的增殖活性。3 H-胸苷给药后2小时处死14、21、28、35和56日龄的动物。显示显著标记指数的细胞类型为14和21日龄动物的柱状细胞; 28、35和56日龄大鼠的主细胞和基底细胞。在此期间的发展，在初始段的细胞活动的模式不同的中间和终端段在第28天的活动高峰。中段和终末段的增殖模式相似。
The proliferative activity of the rat epididymis during postnatal development was investigated with the use of autoradiography. Animals at 14, 21, 28, 35, and 56 days of age were sacrificed 2 hours following the administration of 3H‐thymidine. Cell types that showed a significant labeling index were columnar cells in 14‐ and 21‐day‐old animals; principal and basal cells in 28,35 and 56 day old rats. During this period of development, the pattern of cellular activity in the initial segment differed from the middle and terminal segments in having a peak of activity on day 28. The middle and terminal segments had similar proliferative patterns.
