title: [Immunocytochemical studies of the development of basal cell types of human islet organs].
abstract: The investigations are carried out in 19 human fetal pancreases. The detection of the 4 islet hormones insulin, glucagon, somatostatin and PP ist carried out in PAP-technique. The parts of these 4 types of islet cells are estimated quantitatively. In the 10th to 15th week of development insulin-producing B-cells are present. Moreover glucagon-, somatostatin- and PP-cells in the islet organ are present. In the group of 16th to 20th week of gestation insulin-, glucagon- and somatostatin-cells are increased compared to the first group. PP-cells are not altered. The increase of 3 types of islet cells is a result of fetal development.
