概括。睾丸发育和分化的控制取决于激素和主要由旁分泌因子介导的各种细胞间相互作用。在出生后发育的第二周和第三周,大鼠睾丸发生重要变化,例如管腔在出生后第 10天开始打开,血睾屏障在第 第15天开始形成,支持细胞增殖在第 15天停止。在本研究中,雄激素受体(AR)、孕激素受体(PR)和细胞外基质蛋白(例如层粘连蛋白、巢蛋白-1(nidogen-1)和纤连蛋白)在不同睾丸区室中的表达,在使用免疫组织化学和半定量图像分析检查产后发育。管内 AR 峰值出现在第 14-17 天,管内 PR 表达在第 14-16 天增加,并且在产后第二周和第三周期间管周 enactin-1 表达增加。这些结果表明,在睾丸发育的某些里程碑发生的这一时期,细胞水平发生了多种变化,证实了旁分泌相互作用在大鼠睾丸发育过程中发挥特殊作用的假设。
Summary. The control of testicular development and differentiation depends on hormones and a variety of cell–cell interactions mediated mainly by paracrine factors. In the second and third weeks of post‐natal development important changes take place in the rat testis, e.g. the tubular lumen starts to open on post‐natal day 10, the blood–testis barrier starts to form on day 15, and Sertoli cell proliferation ceases on day 15. In the present study the expression in different testicular compartments of the androgen receptor (AR), progesterone receptor (PR), and extracellular matrix proteins such as laminin, entactin‐1 (nidogen‐1) and fibronectin, during post‐natal development was examined using immunohistochemistry and semiquantitative image analysis. An intratubular AR peak on days 14–17, an increase in intratubular PR expression on days 14–16, and an increase in peritubular entactin‐1 expression during the second and third weeks post‐partum are demonstrated. These results suggest that a variety of changes occur at the cellular level during this period when certain milestones of testicular development occur, substantiating the hypothesis of a particular role for paracrine interactions during the development of the rat testis.
