Around eight days after fertilization, the human embryo implants in the endometrium (the tissue that lines the uterus). After implantation, it enters a developmental phase that is not well understood ...

At this stage, known as gastrulation, a flat and featureless sheet of cells folds into a living blueprint for the body, 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 ...

The development of synthetic embryo models using early stem cells has emerged as a powerful platform for studying mammalian ...

Scientists have created a stem cell-derived model of the human embryo in the lab by reprogramming human stem cells. The breakthrough could help research into genetic disorders and in understanding why ...

Researchers have used stem cells to develop new human embryolike structures that model the earliest stages of fetal development so realistically that they even secrete hormones that can turn a lab ...

Researchers have developed the first-ever embryo-like model from human embryonic stem cells, a workaround that will let them examine birth defects and diseases they couldn’t otherwise, given ethical ...

A new research paper was published in Volume 17, Issue 10 of Aging-US on October 10, 2025, titled "Developmental arrest rate ...

Bioscientists develop a method to observe patterns of early embryonic development, during which ectodermal cells diverge toward their fates as skin, organs and the nervous system. During embryonic ...

Embryo freezing offers high success rates for couples delaying pregnancy. Learn who should consider it, how the process works ...

A bill that aims to require the annual screening of fetal development videos in public schools has passed the Ohio House.
