【答案】：血-睾屏障是指生精小管与血液之间的结构，包括间质中的毛细血管内皮及其基膜、结缔组织、生精上皮基膜和支持细胞侧突之间的紧密连接，其中紧密连接最重要。该屏障一方面可阻止某些大分子物质自由进出生精上皮，确保生精细胞有一个稳定发育的微环境，另一方面还能防止精子抗原物质逸出到生精小管外...
The blood-testis barrier (BTB) is formed adjacent to the seminiferous basement membrane. It is a distinct ultrastructure, partitioning testicular seminiferous epithelium into apical (adluminal) and basal compartments. It plays a vital role in developing and maturing spermatocytes into spermatozoa via reo...
The blood-testis barrier (BTB) is found between adjacent Sertoli cells in the testis where it creates a unique microenvironment for the development and maturation of meiotic and postmeiotic germ cells in seminiferous tubes. It is a compound proteinous structure, composed of several types of cell ...

The blood-testis barrier (BTB) is comprised of the tight junction between the Sertoli cells,forming the stable microenvironment and special immunologic barrier to regulate the opening and closing of BTB. 血睾屏障是生精上皮中以支持细胞间的紧密连接为基础形成的结构,具有形成稳定的微环境和独特的免疫屏障...
The blood-testis barrier (BTB) is conferred by co-existing tight junctions (TJs), basal ectoplasmic specializations (basal ES), desmosome-like junctions and gap junctions (GJs) between adjacent Sertoli cells near the basement membrane in the seminiferous epithelium. While the concept of the BTB ...
