A lot happens in the first month of human embryo development as a single cell morphs into multitudes. Yet despite its significance, this period is basically a “black box” to researchers, says stem ...

Scientists have discovered a kind of “pause button” in early human development. This biological mechanism has long been known in other mammals, but its discovery in humans could aid IVF procedures.

This collection welcomes original research on the molecular basis of embryonic development. Human embryonic development begins with a single fertilized egg and involves complex processes regulated at ...

Human embryo compaction, an essential step in the first days of an embryo's development, is driven by the contractility of its cells. These results contradict the presupposed driving role of cell ...

Physical cues in the womb, and not just genetics, influence the normal development of neural crest cells, the embryonic stem cells that form facial features, finds a new study. Physical cues in the ...

The majority of fertilized eggs die and are resorbed into the body. ZEISS Microscopy/Flickr, CC BY-SA As an evolutionary biologist whose career has focused on how embryos develop in a wide variety of ...

Only about one out of three conceptions leads to birth. 1 Approximately a third of embryos fail to attach to the uterus, while another third is lost after the embryo implants. “Human reproduction is ...

The team observed the emergence of the three-dimensional embryo-like structures under a microscope in the lab. These started producing blood (seen here in red) after around two weeks of development - ...
