Using staged embryos, researchers report a genomic analysis of mouse gastrulation and organogenesis. The post-implantation period is a dramatic one for the mouse embryo. Over the course of about 3 ...
Prior to gastrulation the mouse embryo exists as a symmetrical cylinder consisting of three tissue layers. Positioning of the future anterior-posterior axis of the embryo occurs through coordinated ...
Toward the goal of generating high-quality embryo models in vitro, this study establishes a stepwise protocol to derive trophectoderm-like cells from mouse extended pluripotent stem (EPS) cells. These ...
In a recent study published in the Cell journal, researchers showed that post-gastrulation synthetic embryos (sEmbryos) could be synthesized outside the uterus using mouse naïve embryonic stem cells ...
After fertilization, a human embryo implants into the uterus (day 6-12) and gastrulation starts soon afterwards, with the primitive streak emerging at about day 14. Gastrulation allocates cell fates ...
