为给发育中的各级生精细胞提供适宜的内环境,睾丸支持细胞分泌多种具有不同功能的蛋白质,诸如转移蛋白、生长因子、酶和基底膜成分等。但有关这些物质的资料绝大部分来自实验动物。而有关人睾丸支持细胞分泌的物质,由于医德问题和很难从人睾中分离出纯的细胞群,因而只有少量研究。经多年努力,报告人对取自梗塞性无精子症和有正常生精功能的男子睾丸活检标本用免疫组化技术和光镜、 To provide a suitable internal environment for germ cells at all stages of development, testicular support cells secrete a wide range of proteins with different functions such as transfer proteins, growth factors, enzymes and basement membrane components. However, the vast majority of information on these substances comes from laboratory animals. However, there is only a small amount of research on the substances secreted by human testicular support cells due to medical ethics and the difficulty of isolating pure cell populations from human testis. After years of hard work, the reporter tested the biopsy specimens of male testis taken from infarction-related azoospermia and normal spermatogenesis by immunohistochemistry and light microscopy,
