本实验结果显示，妊娠１８～２０周之人胎胰β细胞在多种内分泌激素的环境中培养了３周尚未能达到功能成熟；ＥＧＦ，ＰＲＬ及ｈＰＬ能增加组织的胰岛含量并促进其急、慢性胰岛素释放；ＧＨ、Ｔ３及Ｈｙｄｒｏｃｏｒｔｉｓｏｎｅ等升糖激素以及含有此升糖激素的多种内分泌激素，在培养早期（１～２周）尚能增加其急、慢性胰岛素分泌，但在培养后期（第三周）则显示其抑制胰岛素分泌的作用、其组织胰岛素含量及胰岛素分泌率均明显减少。 The results of this study showed that human fetal pancreatic β cells from 18 to 20 weeks of gestation had not been able to achieve functional maturation in a variety of endocrine hormones for 3 weeks. EGF, PRL and hPL increased the islet content of the tissue and promoted its urgency , Chronic insulin release; GH, T3 and Hydrocortisone and other hormones and hormones containing this hormone hormones in a variety of endocrine hormones in early (1 to 2 weeks) can still increase its acute and chronic insulin secretion, but in the late Third week) showed its inhibitory effect on insulin secretion, the organization of insulin content and insulin secretion rates were significantly reduced.
