There is variability in when and how cells divide during the development of embryos. While researchers traditionally believed this variability was an obstacle that needed to be regulated, the Hiiragi ...

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 ...

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 ...

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 ...

The two cells that make up a one-day-old human embryo might look identical at first glance. But a study 1 published today shows that most of the human body forms from only one of those cells — 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 ...

On the flipside, if telomeres are too long, it can also spell trouble because cancer cells require long telomeres to become ...

Scientists have long observed that embryos of different species within a phylum look quite distinct at early and late ...

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 ...

Skin wound healing shows a unique cellular function mechanism involving the interaction of several cells, growth factors, and ...

A zebrafish embryo during the first cell division cycle, with the structural protein actin labelled, which marks the cell boundary and ingressing furrow. The image shows a time course from dark orange ...
