Changes in cellular metabolites have been shown to regulate embryonic stem cell development at the earliest stages of life. Metabolites are simple compounds generated during life-sustaining chemical ...

The earliest days after fertilization, once a sperm cell meets an egg, are shrouded in scientific mystery. The process of how a humble single cell becomes an organism fascinates scientists across ...

Researchers at UT Southwestern Medical Center have identified a protein that causes human cell membranes to break open in a ...

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 ...

In addition to endodermal and mesodermal cells, alcohol causes changes in DNA methylation in ectodermal cells (in blue), from which the nervous system and brain develop. During the tightly regulated ...

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 ...

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 ...

Age related decline in female fertility remains one of the most urgent challenges facing reproductive medicine today. The decline affects both the number and the quality of oocytes, which reduces chan ...

Scientists found that embryonic skin cells “whisper” through faint mechanical tugs, using the same force-sensing proteins that make our ears ultrasensitive. By syncing these micro-movements, the cells ...
