【摘要】 用免疫组织化学 PAP 法,显示胰岛 B 细胞,观察大鼠生后发育期间全胰胰岛 B 细胞的形态、分布和数量变化。结果表明,B 细胞多呈园形或椭园形。B 细胞多位于胰岛中央,极少数 B 细胞位于胰腺外分泌部或导管上皮内。B 细胞百分数于1d 组最低,28d 组最高。结果提示,大鼠生后发育期间胰岛 B 细胞在继续发育。B 细胞具有其内胚层起源的形态学基础。更多还原

【Abstract】 Pancreatic B cells were displayed by PAP immunohisto— chemical technique.Observation was made on morphology,distribution and population of rat pancreatic B cells during postnatal development.B cells appeared as circular or ovoid structure B cells were mainly located in the center of pancreatic islets,a few of B cells were seen in the exocrine portion of the pancreas or in the epithelia of the pancreatic ducts.The percentage of B cells was lowest in the 1st day group and highest in the 28th day group.The results suggested that the B cells continue to change during postnatal development.The distribution of B cells supported the theory that the B cells originated from the endoderm.更多还原
