Embryonic germ layers are the fundamental organizing principle in animal development. They provide the structural basis from which tissues and organs arise. During early embryogenesis, cells divide to ...
Descriptions of the embryo go back at least to the time of Aristotle, but it has only been since the late 19 th century and early 20 th century that advances in experimental approaches allowed ...
A new discovery by researchers challenges our current understanding of gastrulation, the most important stage of early embryonic development. When the zygote, or the fertilised egg, starts to develop, ...
Advances in genetic and computational tools have enabled researchers to study complex networks of gene expression in individual cells, and the patterns of gene expression in a population of cells ...
Researchers uncovered key networks that simultaneously control pluripotency and readiness for cell death (apoptosis), helping to ensure optimal conditions for embryonic development. The study's ...

How does the embryo develop during the third week of pregnancy?
Week 3 of pregnancy is a critical stage when the embryo begins to grow rapidly. During this week, cells divide at an astonishing rate, laying the foundation for all future tissues and organs. This ...
Primordial germ cells, which emerge around day 16 in early human embryos, develop to form oogonia so that eventually, the number of oocytes that are present in an adult female is fixed at birth. After ...
In their publication in Science, Professor Guojun Sheng (Kumamoto University, Japan), Professor Alfonso Martinez Arias (Universidad Pompeu Fabra, Spain) and Professor Ann Sutherland (University of ...
