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...
Blood-tissue barrier in testes;Seminiferous epithelial barrier;Sertoli cell barrier Definition The blood-testis barrier (BTB) is a blood-tissue barrier found in the testis, located near the base of the seminiferous epithelium (Fig.1) as noted in the cross section of seminiferous tubules which are...
[名词解释] 血-睾屏障(blood-testis barrier) 相关知识点: 试题来源: 解析 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...
Blood-testis barrier 相关知识点: 试题来源: 解析 又称Sertoli细胞。细胞呈不规则的长锥形,细胞基底紧贴在基膜上,顶部伸向腔面。其侧面镶嵌有各级生精细胞,故光镜下细胞轮廓不清。核呈三角形或不规则形,染色浅,核仁明显.电镜下胞质内含大量的滑面内质网和一些粗面内质网、高尔基复合体、线粒体和溶酶体,并有许多...

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 ...
