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 ...

For the first time, a stem cell model has produced a structure resembling an early human embryo with a yolk-sac-like ...

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 ...

Scientists are exploring ways to mimic the origins of human life without two fundamental components: sperm and egg. They are coaxing clusters of stem cells – programmable cells that can transform into ...

By examining genetic clues that linger in adult cells, scientists have now gained surprising insights into the developmental ...

During embryonic stem cell (ESC) development, pluripotent stem cells transition from a naïve state into a primed state before they take their first steps toward a lineage commitment. Jacob Hanna, a ...

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, ...
