... phylogenetically distant species (bovine and rabbit) does not impede TE differentiation, blastocyst formation and the expression of TE markers, such as GATA3 and CDX2, although a reduced number of cells in the inner cell mass was observed in bovine TEAD4 knockout (KO) blastocysts. Transcriptional analysis...

... on the mouse. Here, we provide a comprehensive, stage-by-stage analysis of EPI and extra-embryonic primitive endoderm (PrE) formation during preimplantation development of the rabbit. Although we observed that rabbit embryos have several features in common with mouse embryos, including a stage-related...

... process by which embryos integrate signals from outside and later regulate gene expression, we linked Ca 2+ signal parameters i.e. amplitude, number and frequency, with the efficiency and quality of postimplantation development. Freshly ovulated rabbit oocytes were subjected to repetitive and modulated Ca...

... of keratins. In our experiments, central adult rabbit corneal epithelium was thus associated either with a mouse embryonic dorsal, upper-lip or plantar dermis before grafting onto nude mice. Complementary experiments were performed using adult mouse corneal epithelium from the Rosa 26 strain. The origin...

... the inductive potential of the mammalian visceral endoderm, we used rabbit embryos which, in contrast to mouse embryos, allow the morphological recognition of the prospective anterior pole in the living, pre-primitive-streak embryo. The anterior visceral endoderm from such rabbit embryos induced neuralization...

...Jean Pierre Ozil ABSTRACT Freshly ovulated rabbit oocytes were activated parthenogenetically by periodically repeated calcium stimuli generated by electric field pulses applied onto the plasma membrane. Electric field pulses of 1.8 kV cm -1 were delivered every 4 min for 1h 30 min (22 double pulses...
