The occurrence of a gastrin-like immunoreactivity in the alimentary tract of the ascidian Styela plicata has been investigated using immunocytochemical methods. Gastrin-like cells are present only in the gastric epithelium among the cell types responsible for digestion and absorption of food. The physiological role played by the ascidian gastrin-like peptides is discussed together with the evolutionary history of peptides of the gastrin/cholecystokinin family.
利用免疫细胞化学方法，对皱瘤海鞘消化道中胃泌素样免疫反应性的发生情况进行了研究。在负责食物消化和吸收的细胞类型中，胃泌素样细胞仅存在于胃上皮中。本文结合胃泌素/胆囊收缩素家族肽的进化史，对海鞘胃泌素样肽所发挥的生理作用进行了讨论。
