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 ...

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 ...

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 ...

The beginning of life is shrouded in mystery. While the intricate dynamics of mitosis is well-studied in the so-called somatic cells – the cells that have a specialized function, like skin and muscle ...

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 ...

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 ...
