The three-dimensional structure of the Sertoli cell in the miniature "shiba" goat was examined using scanning electron microscopy. In the basal portion of the seminiferous epithelium, spermatogonia and/or spermatocytes were located in compartments enclosed by adjacent Sertoli cells. From the basal aspect, they were situated in successive recesses. In the middle portion, early round spermatids halfway embedded in the Sertoli cell were recognized. The exposed surfaces of these spermatids were wrapped with ramifying processes which were derived from the Sertoli cell. In the apical portion, only the heads of the maturing spermatids invaded the Sertoli cell. As the spermatid matured, the apical Sertoli process varied in range to finally release the spermatid head. It is probably that the maturing spermatids gradually leave the apical Sertoli process and ultimately segregate themselves from the seminiferous epithelium.
利用扫描电子显微镜对小型“柴”山羊支持细胞的三维结构进行了研究。在生精上皮的基部，精原细胞和/或精母细胞位于相邻支持细胞围成的隔室内。从基部观察，它们位于连续的凹陷处。在中部，可以识别出半嵌入支持细胞的早期圆形精子细胞。这些精子细胞的暴露表面被源自支持细胞的分支突起所包裹。在顶部，只有成熟精子细胞的头部侵入支持细胞。随着精子细胞的成熟，顶部支持细胞突起的范围发生变化，最终释放出精子细胞头部。成熟的精子细胞可能逐渐离开顶部支持细胞突起，最终从生精上皮中分离出来。
