前言有关哺乳动物精子生成细胞的研究表明,在精子、精子细胞及精母细胞(精原细胞除外)的膜上有通常不存在于体细胞的抗原决定簇。这些研究结果得出的结论是:由足细胞形成的血睾屏障提供了特异的精子生成抗原的生成环境。这些抗原可能参与哺乳动物睾丸细胞间的相互反应及细胞分化过程。 Introduction Studies in mammalian spermatogenic cells have shown that there are antigenic determinants that are not normally found in somatic cells in the membranes of spermatozoa, sperm cells and spermatocytes (other than spermatogonia). These findings lead to the conclusion that the blood-testis barrier formed by podocytes provides a specific environment for the generation of spermatogenic antigens. These antigens may be involved in mammalian testicular cell interactions and cell differentiation processes.
