[Further contribution on glycogen in fetal intestinal epithelium]

In the first half of pregnancy the well-known occurrence of glycogen incorporation in the supra- and infranuclear cytoplasm of the villous enterocytes was verified. This enormous glycan store is evidently of very little functional importance. It seems to be an expression of a disordered glycogenolysis. These masses of glycogen are incorporated into impressive glycogenosomes, which are the predominante cytoplasmic inclusions for a short period of time. According to the present results it is not certain whether lysosomal glycogenolysis happens. There is no morphological or functional evidence for a utilization og glycogen.
