How does an embryo develop? From Egg to Embryo First, the zygote becomes a solid ball of cells. Then it becomes a hollow ball of cells called ablastocyst. Inside the uterus, the blastocyst implants in the wall of the uterus, where it develops into an embryo attached to a placenta and s...
"This is the first scientific publication to achieve this result," said Whitelaw, who was not involved in the study, "(It) paves the way for significant advances in our understanding of cell lineage development in the embryo and hints towards future novel biotech applications."...

26, 2017 shows a 4-week-old pig embryo containing human cells. In a bold but potentially controversial quest for solutions for the worldwide shortage of transplant organs, scientists attempting to grow human organs inside pigs have successfully grown the first chimera embryos containing cells from ...
First developmental signs of the scolopale (glial) cell and neuron comprising the chordotonal organ in the Drosophila embryo. Glia 19, 269-74.Carlson, S. D., Hilgers, S. L. and Juang, J.-L. (1997a) First devel- opmental signs of the scolopale (glial) cell and neuron comprising ...
the multipotent TE and the pluripotent ICM. TE cells develop into the extraembryonic tissues, while ICM cells are able to give rise to the embryo proper and another extraembryonic tissue, the primitive endoderm (PE)5. How TE and PE form the fetal part of the placenta is described in more ...

In lab tests in culture, the team started with monkey blastocysts. Six days after fertilization they were injected with 25 human extended pluripotent stem (hEPS) cells, which contribute to the tissue as the embryo develops. And sure enough, when the researchers examined the batch of embryos 24...
The first trimester of pregnancy is a 3-month span of remarkablegrowth and development. The embryo, microscopic in size near the beginning of this period, transforms into a fetus approximately 80 mm in length with identifiable features and internal organs by the end. (Note: by convention, the...
