Bovine ovaries were collected in 37 °C prewarmed 0.9% sterile NaCl solution and transported from the local slaughterhouse to the laboratory. The ovaries were washed twice with fresh, warm, sterile 0.9 ...

Metabolism does more than fuel embryos—it sets their developmental rhythm. EMBL researchers found that a sugar molecule, FBP, controls the pace of spine formation, suggesting metabolism may act as a ...

Protein modifications are key to cell survival because they ensure they do what they are supposed to do in a healthy system. One vital modification involves adding sugar molecules to proteins, a ...

A new study reveals that age-related autophagy decline blocks embryo development by triggering a lipid-burning crisis.

During animal development, embryos undergo complex morphological changes over time. Differences in developmental tempo between species are emerging as principal drivers of evolutionary novelty, but ...

The second wave directs glucose through glycolysis, providing energy and metabolites necessary for mesodermal cell migration and lateral expansion. The team mapped the spatial and temporal patterns of ...

Descriptions of the embryo go back at least to the time of Aristotle, but it has only been since the late 19 th century and early 20 th century that advances in experimental approaches allowed ...

An international team of experts in embryology and bioethics has published the first white paper on the use of embryonic models based on stem cells in the field of reproductive biology. The document, ...

In order for vertebrate embryos to develop their body axes, they require what is known as an embryonic signaling center. This ...

For several years, researchers studied human embryonic stem cells (ESCs) to understand the unique features of these pluripotent cells, but on their own, they poorly resembled the complex structures ...
