Detection of maternal esterase in mouse embryonic tissues.

A genetic variant of esterase in mice is used to demonstrate for the first time that an enzyme of maternal origin is taken up intracellularly by two mid-gestation tissues dervied from the embryo: trophoblast and yolk sac (visceral endoderm). Although other alternatives are still possible, it is likely that the esterase is transported from the mother to the trophoblast via the serum. If so, the ...

Detection of Glycoconjugate Changes in the Embryonic Trigeminal Nucleus in Balb/C Mouse by Lectin Histochemistry

Purpose: Determination of changes of glycoconjugates, which have special terminal sugars, in embryonic developmental processes of brain stem and trigeminal nucleus in Balb/C mouse. Materials and Methods: In this study mice embryos between 10-17 embryonic days were used. They were fixed according to ordinary laboratory procedures. The specimens were embedded in paraffin and serial sections with...

Enzyme analysis of mouse extra-embryonic tissues.

We have separated for enzyme analysis the following layers that surround the conceptus at midgestation: decidua, trophoblast, parietal endoderm (including Reichert's membrane), visceral endoderm, yolk-sac mesoderm and amnion. Measurement of several catabolic enzyme activities (N-acetyl-beta, D-hexosaminidase, beta-glucuronidase, alkaline and acid phosphatases and non-specific esterases) in thes...

The Effect of chick Embryonic Somites on Neural Rosette Formation in Mouse Embryonic Stem Cells

purpose: The aim of the present study is to understand if EBs can generate neural rosette upon co-culture with chick embryo somites. Materials and Methods: The mouse ES cells, line Royan Bl, were cultured in hanging drops to induce embryoid bodies (EBs) formation. Somites were isolated from the chick embryos and then embedded in alginate solution. Finally, alginate beads containing somites were...

Maternal BCAS2 protects genomic integrity in mouse early embryonic development.

Mammalian early embryos maintain accurate genome integrity for proper development within a programmed timeline despite constant assaults on their DNA by replication, DNA demethylation and genetic defects transmitted from germ cells. However, how genome integrity is safeguarded during mammalian early embryonic development remains unclear. BCAS2 (breast carcinoma amplified sequence 2), a core com...
