The mouse embryos, developed using stem cells, only lasted ... but at a very early stage of development, a rare event which, while superficially looking like an embryo, bears defects which should ...

During embryonic development, the pluripotent stem cells of the early embryo produce more specialized, multipotent stem cells, which can only make for instance the cells of a specific tissue. Blood ...

Researchers at the University of Pittsburgh have unveiled a revolutionary embryo ... development. This innovative model successfully reproduces key features, notably the generation of blood cells ...

While most animal cells are specialised and have fixed roles, such as skin cells, nerve cells or blood ... tested in mouse stem cell cultures, we found that choanoflagellate SOX proteins could ...

Three-dimensional visualization of nerves (green) and blood vessels (magenta) in a mouse embryo. Developmental biologist Kat Hadjantonakis works to gain insights into the critical events that direct ...

Additional studies show that the NSET procedure is effective for transfer of mouse embryos for the purposes of rederivation, cryorecovery, and transgenic research. Embryos can be successfully ...
