Mice with two male parents that lived to adulthood have been created by stem cell scientists. But the genetically engineered rodents were unable to reproduce. Chinese researchers used embryonic stem ...

Extraembryonic trophoblast lineages constitute the placenta, and are essential for individual development. In human early embryo development, these cells can be generated from totipotent blastomeres.

As well as being essential in the precise packaging of DNA into the space of the nucleus, histone proteins are also the site ...

Jan. 28, 2025 — A team of stem cell scientists have successfully used embryonic stem cell engineering to create a bi-paternal mouse -- a mouse with two male parents -- that lived until adulthood.

Conventional human pluripotent stem cells at the primed pluripotent state are capable of generating all the embryonic lineages. However, their ...

Embryonic stem cells (ESCs) can be propagated indefinitely in culture, while retaining the ability to differentiate into any cell type in the organism. The molecular and cellular mechanisms ...

Researchers created the first bi-paternal mouse by modifying imprinting genes, advancing reproductive science but facing ...
