In the rat pineal gland the mechanism of release of secretory material was studied ultrastructurally after incubating tissues in Ringer solution containing tannic acid. The results indicate that pinealocytes release the contents of secretory vesicles into the extracellular space via exocytosis, a phenomenon that has not been visualized previously in this cell type. This finding may reflect release of polypeptides by the pineal gland.
在大鼠松果体中,将组织置于含鞣酸的林格氏液中孵育后,利用超微结构研究了分泌物质的释放机制。结果表明,松果体细胞通过胞吐作用将分泌囊泡的内容物释放到细胞外空间,这种现象此前在该细胞类型中尚未观察到。这一发现可能反映了松果体释放多肽的情况。
