Scientists have uncovered a surprising new way that giant embryonic cells divide—without relying on the classic “purse-string” ring long thought essential for splitting a cell in two. Studying ...

A collaboration between research groups at the University of California, TU Dresden in Germany and Cedars-Sinai Guerin Children’s in Los Angeles has identified a mechanism by which embryonic cells ...

Researchers at the University of Connecticut have reported a novel bovine embryonic stem cell line with improved pluripotency and broader translational potential. The platform has opened routes ...

Embryonic stem cells (ESCs) are found in the inner cell mass of the human blastocyst, an early stage of the developing embryo lasting from the 4 th to 7 th day after fertilization. In normal embryonic ...

Roe deer are among the few mammals whose embryos go into a particularly long period of dormancy. Using modern molecular methods, researchers have shown for the first time what exactly happens in the ...

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 ...

Multicellularity is one of the most profound phenomena in biology, and relies on the ability of a single cell to reorganize itself into a complex organism. It underpins the diversity in the animal ...

Jennifer Zenker receives funding from NHMRC and Viertel Foundation. Most people have heard of stem cells. They are often described as “miracle” cells –ones that can grow into any other type of cell in ...

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 ...

BEIJING -- After years of dedicated research, a team of Chinese scientists has unveiled critical mechanisms governing early human embryonic development, offering novel theories and potential ...
