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 ...

Research reveals that variability in when and how cells divide in embryos is beneficial for development. By studying embryos from mice, rabbits, and monkeys, the team found that this randomness helps ...

Unveiling the mysteries of cell division in embryos with timelapse photography With the help of medaka fish, CRISPR and new imaging techniques, researchers have set a new standard for studying ...

In contrast to mammalian early embryos, embryonic cells in fish are transparent and develop synchronously in a uniform, single-cell layer sheet, which makes them significantly easier to track.

During early embryonic development, cells undergo at least one asymmetric division and sometimes several more: They produce daughter cells that differ in size and fate, laying the foundation for the ...

It was long thought that during an embryo's first cell division, one spindle is responsible for segregating the embryo's chromosomes into two cells. Science publishes the results - bound to change ...

The synchronous mitosis of early embryonic development switches to a patterned form at the 11th cell division following removal of a cell cycle compensatory mechanism, new research shows. An ...
