This video offers a captivating look at the key stages of human embryonic development—from fertilization to the early ...

Analyzing embryo movements in uteruslike environments could offer clues to improving the success rate of in vitro fertilization ...

Sixty percent of miscarriages are caused by the failure of an embryo—the developmental stage before a fetus—to implant in the woman’s uterus. Part of the problem is that researchers have no idea how ...

Researchers created an embryo model that looks and acts like a natural human embryo. They say it’s an ethical way of gaining a better understanding of embryonic development that may provide ...

Early-stage human embryos are difficult to obtain. Then there are ethical issues surrounding their use. This has made it difficult for scientists to understand early human development.

The team turned human embryonic stem cells into embryoids that model early human embryos. Like their biological counterparts, the lab-based blobs developed major “layers” of tissues defining the early ...
