WASHINGTON (Reuters) - Mouse embryos created through a "virgin birth" process called parthenogenesis show that egg cells can be a source of valued embryonic stem cells, researchers said on Thursday.

Study finds that large embryo cells divide step by step using a mechanical ratchet system, challenging the textbook idea of a ...

New research sheds light on embryonic mitosis, thanks to a combination of novel imaging techniques, CRISPR/Cas9 genome editing technology, a modern protein-knockdown system, and medaka, or Japanese ...

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 ...

Symmetry is a fundamental characteristic of most multi-cell animals. However, the cell division of embryonic cells is asymmetric. A team led by Prof. Dr. Esther Zanin at the Department of Biology at ...

Egg whites may be perfect for a health-conscious breakfast, but egg yolks turned out to be the key ingredient for cultivating bird embryonic stem cells (ESCs) in the lab. Using a growing medium of egg ...

Cell division is an essential process for all life on earth, yet the exact mechanisms by which cells divide during early embryonic development have remained elusive – particularly for egg-laying ...

Single-molecule imaging shows that three CBX2 protein molecules can seed Polycomb condensates that silence genes in stem cells. The discovery reveals how rare proteins organize genome regulation and ...
