Development of Fetal Monolayer Culture Rat Intestine in Organ and

Maturation and differentiation of intestinal epithelial cells was demonstrated in segments of fetal rat small intestine, maintained for more than a month in suspension organ culture, by ultrastructural, biochemical, and immunological criteria. Over a 5-7 d period, fragments of fetal intestine evolved into globular structures covered with a single columnar epithelium ultrastructurally similar to...

Intrinsic factor receptor during fetal development of the human intestine.

Intrinsic factor receptor activity was observed in mucosal homogenates from whole small intestine and colon of 10-19-week fetuses, whereas it was only detected in the distal part of the small intestine of a 25-week fetus. The receptor-intrinsic factor-cobalamin complex was eluted into the void-volume position when ileum mucosal extract was assayed for receptor activity by gel filtration after i...
