Created from stem cells, without eggs, sperm, or a womb, the embryo model had a yolk sac and a proto-placenta, resembling a state that real human embryos reach after approximately 14 days of ...
Early development of an embryo is solely supported by maternally deposited RNAs and proteins until its own genome is activated through a process called zygotic genome activation (ZGA). Recent research ...
Interactions between modified maternal folic acid intake and Tet1 gene dosage affect embryonic phenotypes, metabolism, and DNA methylation post neural tube closure. Epigenetic dysregulation may ...
How did the characteristic pattern of embryonic cell divisions during animal development evolve? Analysis of the multicellular development of an organism related to animals now provides some answers.
