Development of mucosa of the human ileum.

摘要: Normal histology, glycogen and alkaline phosphatase have been studied in the mucosa of human fetal ileum between 28 140 days gestation. From 112 onwards, perinuclear, supranuclear infranuclear vacuolation, striate border, basement membrane columnar epithelial cells villi, very close proximity latter to blood vessels, all support idea that are actively engaged transport materials. Alkaline become conspicuous at this stage. It is argued by absorbing glucose amniotic fluid as well secreting mucus.
