Segi's cap, a large aggregation of endocrine cells on the intestinal villi, occurs also in cattle and pig fetuses.
Segi's cap, a huge aggregation of basal-granulated cells on the top of the intestinal villi has been known only in human fetuses. This study reveals that the peculiar structure occurs also in cattle and pig fetuses. Segi's cap in these animals mainly consists of argyrophil endocrine cells and, in the cattle fetus, includes gastrin-, somatostatin-, motilin- and secretin-immunoreactive cells.
