用免疫组织化学PAP法对45例2月～足月新鲜胎儿及出生后2天婴儿的胃窦胃泌紊细胞(G细胞)进行了定性和定量的研究。G细胞于胎龄3个月的胎儿胃窦粘膜内开始出现,数量极少。以后随胎龄的增长而递增。G细胞形态多样,有的细胞有突起,并可借突起与其他腺细胞相接触。细胞的顶端或突起朝向或达到管腔。本观察结果提示G细胞除具有内分泌和旁细胞分泌的形态学证据。 Immunohistochemical PAP method was used to qualitative and quantitative study of gastrocytic gastrocnemius cells (G cells) from 45 infants born in February to full term and infants born 2 days later. G cells in fetal gestational age 3 months of fetal gastric mucosa began to appear, the number of very small. After the increase with the increase of gestational age. G cells are diverse in shape, and some cells have protrusions that can be contacted with other gland cells by protrusions. The tip or protrusion of the cell faces or reaches the lumen. This observation suggests that G cells have morphological evidence of endocrine and paracellular secretion.
