title: Gastrointestinal somatostatin cells in the human fetus.
abstract: The stomach, duodenum, jejunum and ileum from 6 to 24 week-old human fetuses or deceased premature infants and from one totally anencephalic fetus were stained with antisomatostatin serum. The somatostatin containing cells appear in different segments of the gastrointestinal tract from the tenth week of gestation. The somatostatin-containing cells are lead haematoxylin positive. Somatostatin was also detected in the duodenum of the anencephalic fetus. The study of inhibition of the immunofluorescent reaction by homologous and heterologous antigens confirmed the specificity of antiserum. These data demonstrate that somatostatin can be synthetized elsewhere than in the hypothalamus.
