Glycolysis is an ancient metabolic activity. It consists of a set of reactions that convert glucose into energy. This central ...

These clusters of cells are increasingly at the center of legal disputes, resulting in piecemeal decisions that have far-reaching consequences.

Studying the early development of human embryos is challenging due to ethical constraints and technical difficulties. Therefore, animal models are often used to understand the biological processes ...

A study reveals that guinea pigs can serve as a robust model for understanding human pre-implantation development. Their ...

Researchers reveal that the guinea pig pre-implantation embryo is very similar to the human embryo, spurring a better understanding of infertility and early human development.

After three long essays in the New York Times ’s “Embryo Question,” the series ends with a stunning confession of complete indecision about what the human embryo is — aside from the assertion that ...

The study, published in STEM CELLS Translational Medicine, used human embryonic stem cells, or hESCs, to characterize early stages of embryonic development and examined how low concentrations of ...

it might require to prove to regulators and patients that CRISPR could be safely used to alter the genome of a human embryo. If, of course, society decided that was a good idea. Joung, an early ...

“When we compared the development of the guinea pig embryo to our previous work, we were very surprised by its striking resemblance to early human embryogenesis.” That discovery opens new ...

The results show that the preimplantation development of guinea pigs, i.e., the time before the embryo attaches to the uterine wall, is surprisingly similar to that of humans. They also identified ...
