fused to a membrane trafficking sequence into one of the two cells of the zygote. Thus, they could determine the contribution of each cell to the development of two early structures: the trophectoderm ...

Becoming an embryo and attaching and forming a fetus is evidence that there is a new individual that is “on the path.” This ...

The mice were created by Colossal Biosciences, which edits DNA for species conservation, and has been working to bring back the woolly mammoth since 2021.

After a sperm fertilizes an egg, the totipotent cell divides into a zygote. As division continues, some cells divide into the growing mass, distinguishing cells that form the embryo (epiblast) from ...

These two haploid cells produce a diploid zygote. Hormonal control of reproduction Hormones control puberty, the menstrual cycle, and sperm production and play a crucial role in in the control of ...

Development is the process of growth of the individual from zygote to adult. It includes the coordinated processes of cell proliferation, motility and differentiation, the patterning of organs ...

A research team at Kumamoto University has developed a deep learning-based method for analyzing the cytoskeleton—the structural framework inside cells—more accurately and efficiently than ever before.

Relying on CRISPR, they then took both the stem cell and zygote approach to rewriting the mouse’s stem cell to express those traits. The next steps involved more than a little hit and miss.
