Mouse stem cells for primitive endoderm established

Stem cells that give rise to the mouse yolk sac have been isolated and cultured in the lab for the first time by RIKEN researchers, raising the possibility of artificially creating mouse embryos from stem cells in the future.

Precursor of spine and brain forms passively

Researchers at ETH Zurich have conducted a detailed study of neurulation—how the neural tube forms during embryonic development. They conclude that this happens less actively than previously thought. This also has implications ...

Tethers bring distant genes together to coordinate embryo development

Organisms such as plants, mammals and insects undergo a carefully orchestrated developmental program as they transition from single-celled embryos to their multicellular adult forms. In a paper that appeared May 4, 2022 in ...

Water filtration membranes morph like cells

Morphogenesis is nature's way of building diverse structures and functions out of a fixed set of components. While nature is rich with examples of morphogenesis—cell differentiation, embryonic development and cytoskeleton ...

Embryogenesis (compound of the Greek: εμβρυο-γένεσις "embryo-genesis") is the process by which the embryo is formed and develops. It starts with the fertilization of the ovum (or egg) which, after fertilization, is referred to as a zygote. The zygote undergoes rapid mitotic divisions with no significant growth (a process known as cleavage) and cellular differentiation, leading to development of an embryo. It occurs in both animal and plant development, this article addresses the common features among different animals.
