本文报道了经Ham’s F_(10)培养的人胎胰组织胰岛细胞功能状况及扫描电镜检查所见.发现培养物的胰岛素和C 肽分泌功能从被培养后的第3天开始增强,第7天后减弱,第10天后明显低落,分泌曲线呈抛物线型。在其分泌功能旺盛的3～7天期间,电子显微镜下可见群集的胰岛B 细胞颗粒占总体的3/4,也可见散在的胰岛A 细胞.7天以后的功能衰退期,则见A、B 细胞分泌颗粒电子密度减低,影像模糊,难以辨认. This article reports the functional status of human fetal pancreatic islets cultured by Ham’s F 10 and the results of scanning electron microscopy showed that the secretions of insulin and C-peptide in culture increased from the third day after culture, Weakened significantly after 10 days, the secretion curve was parabolic. During the 3-7 days of exuberant secretion, clusters of islet B cells accounting for 3/4 of the total were seen under an electron microscope, and scattered islet A cells were seen.7 days after the functional decline, see A, B The electron density of the cell secretory particles is reduced, and the images are blurred and illegible.
