摘要
用盐酸—吐温法除去结缔组织细胞间质后,在扫描电镜下观察了大鼠肾髓质间质细胞。依细胞外形,肾髓质间质细胞可分为有突起的和无突起的两类;有突起的又可分为杆状胞体和球状胞体两种。杆状有突起的间质细胞最多,横行连接在血管和肾小管之间,细胞突起在血管壁和肾小管壁上形成致密网,有的突起末端膨大为球盘状,附着于血管壁。球状有突起间质细胞数量较少,散在于髓质,其突起细小,附着于邻近的血管或肾小管壁上。无突起细胞数量亦少,附着于杆状有突起间质细胞的胞体上。本文并扼要讨论了它们的功能意义。
The renomedullary interstitial cells(RMIC)of rat were investigated using the method of HCl-Tween removing extracellular material and scanning electron microscope.According to the shape and distribution,the RMIC may be divided into 3 groups.However,most of RMIC belong to the first group.The cell of the first group is fibroblast-like,which has an irregular cylindrical body(about 2-6μm in short diameter and 5-12μm in long diameter)and several processes from both ends of the body.The processes from one end are distributed on the wall of the renal tubule(Henle’s loop or collecting tubule);and those from the other end on the blood vessel,sometimes,with the vascular pedicles formed by the expanding of the process end.The long axis of the cells of the first group is perpendicular to the tubules and blood vessels,so the cells are bridged between them.The second group cell has a round body without process and is located at the body of the first group cell.The third group cell is star-like,which has a large body(about 5-8μm in diameter)and a few small processes.They are randomly distributed,and sometimes,arranged as a line along the blood vessel.
