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 ...

Metabolic regulation is critical in embryonic development and influences key processes such as fertilization, zygotic genome activation, cell compaction, implantation, gastrulation and organ ...

Embryonic development, also known as embryogenesis, is a cornerstone in understanding the origins of life. But studying this marvel of intricate and layered biological processes in people faces ...

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 ...

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 ...

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 ...

Using CRISPR-based engineering methods to prompt stem cells to organize into embryo-like structures, scientists were able to create 'programmable' cellular models of embryos without ever experimenting ...

Bioengineering researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have developed a soft, thin, stretchable bioelectronic device that can be implanted into a ...

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 ...

A recent Nature study evaluates post-implantation development in humans using embryo-like models based on genetically unmodified human naïve embryonic stem cells (ESCs). Study: Complete human day 14 ...

Chimpanzee naive pluripotent stem cells (PSCs) can now be grown in cellular cultures, reveals a recent study. They successfully created chimpanzee early embryo models, called 'blastoids,' and found ...
