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 ...
On the flipside, if telomeres are too long, it can also spell trouble because cancer cells require long telomeres to become longer lived, ‘immortal,’” says Mia Levine, associate professor of biology ...
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 ...
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 ...
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 ...
Scientists have long observed that embryos of different species within a phylum look quite distinct at early and late ...
In a scientific breakthrough that raises a number of medical and ethical issues, researchers have used stem cells to create living, growing models of a human embryo. Because stem cells were used, ...
Timelapse of a gene-edited medaka fish embryo undergoing mitosis. The mitotic spindle – the green strands in the middle of the cells – can be seen aligning and segregating duplicated chromosomes, ...
