The human yolk sac and yolk sac carcinoma. An ultrastructural study.

Human pathology, 1977
The ultrastructure of the yolk sac of a 39 day old human embryo was studied. The subcellular organization was suggestive of a highly specialized absorptive function proceeding in an exocelomic-viteline direction. These findings, compatible with intense metabolic activity, are at variance with the concept of rapid involution of the yolk sac following ...

On the yolk sac of the cat

Cell and Tissue Research, 1976
The ultrastructure of feline yolk sacs from 11 stages between the 14th and the 66th day is described with reference to the endoderm and the mesothelium; supplementary histochemical and cytochemical studies are included. Despite the absence of yolk, the endodermal epithelium shows a high degree of differentiation and activity, especially in the period ...

Yolk sac fluid and yolk sac membrane enzymes in the marsupial, Macropus eugenii

Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1974
Abstract 1. 1. Yolk sac membrane incorporated radiocarbon into hexose phosphates, amino acids and several intermediates of the glycolytic pathway and tricarboxylic acid cycle. Yolk sac fluid likewise incorporated radiocarbon, but into fewer compounds. 2. 2.
