摘要
纤溶酶原激活因子 (PA)及其抑制因子 (PAI)参与机体的多种生理、病理活动。支持细胞是睾丸精曲小管的重要组成部分 ,其正常功能的发挥对精子发生等生物学行为的正常进行具有非常重要的意义。睾丸支持细胞在激素及其他因子的作用下 ,分泌PA及PAI,发挥生物学作用 ,维持正常的精子发生、精子活力及受精过程 。
Plasminogen activator(PA) and plasminogen activator inhibitor(PAI) are involved in many physiological or pathological events. The Sertoli cells, the important elements within the seminiferous epithelium, are thought to play a key role in spermatogenesis. The Sertoli cells secrete PA and PAI. The levels of them are modulated by hormonal and cell mediated influences. They play a fundamental role in the maintenance of spermatogenesis, sperm motility and fertilization.
