Transdifferentiation of mouse visceral yolk sac cells into parietal yolk sac cells in vitro
Biochemical and Biophysical Research Communications, 2016The mouse embryonic yolk sac is an extraembryonic membrane that consists of a visceral yolk sac (VYS) and parietal yolk sac (PYS), and functions in hematopoietic-circulation in the fetal stage. The present study was undertaken to examine the normal development of both murine VYS and PYS tissues using various molecular markers, and to establish a novel ...

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, 1974Abstract 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.

Experientia, 1978 Ultrasonography of the Human Yolk Sac
1993Static scanners gradually became to be widely used in obstetrics following a report of the detection of fetal echoes at 14 weeks of gestation (Donald et al. 1958). During the mid-1970s, growth parameters of the gestational sac and embryo as from 6 weeks of gestation were measured using gray scale static scanners; the clinical criteria for the ...
