Segi's cap: huge aggregation of basal-granulated cells discovered by Segi (1935) on the intestinal villi of the human fetus.
Basal-granulated cells form a large aggregation on the top of villi in the duodenum and upper jejunum of the human fetus. This peculiar structure was discovered and precisely described by Segi (1935) but long neglected by later researchers. This paper proposes to call it "Segi's cap" and preliminarily reports some new findings of our own.
