The endocrinous part of the pancreas in the mammals under investigation (rats, guinea pigs, cattle, cats and man) comprises A-, B- and D-cells always disposed around capillaries were prevailing in all the animals. They excrete the secretory product immediately into the pericapillary gap. A-cells in rodents and man are located in the periphery of the island and often have no contacts with capillaries. The secretion from A- cells having no contacts with capillaries is released into intercapillary clefts into which the cytoplasmic spiculae of the adjacent exocrinous pancreacytes are turned, capable to overlap them and prevent from the entering of the hormone from the intercellular clefts into the pericapillary gap.
在被研究的哺乳动物（大鼠、豚鼠、牛、猫和人类）中，胰腺的内分泌部分由A细胞、B细胞和D细胞组成，这些细胞总是围绕着毛细血管排列，在所有动物中都占主导地位。它们将分泌产物直接排入毛细血管周围间隙。啮齿动物和人类的A细胞位于胰岛的外周，通常与毛细血管没有接触。没有与毛细血管接触的A细胞分泌的物质释放到毛细血管间裂中，相邻外分泌胰腺细胞的细胞质细刺会伸向这些裂，能够覆盖它们并阻止激素从细胞间裂进入毛细血管周围间隙。
