Some newly reported clumps of cells growing in lab dishes have been hailed as the closest things to human embryos that scientists have ever made in the lab. These entities are human embryo models — ...

How does the embryo develop during the third week of pregnancy?
Week 3 of pregnancy is a critical stage when the embryo begins to grow rapidly. During this week, cells divide at an astonishing rate, laying the foundation for all future tissues and organs. This ...
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 ...
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 ...
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 - ...
Scientists have created synthetic blobs that resemble a 14-day-old human embryo for the first time, meaning they can study embryo development beyond a particularly tricky period of pregnancy.
A small tissue fold in fly embryos, once thought purposeless, plays a vital role in stabilizing tissues. Researchers show that it absorbs stress during early development, and its position and timing ...
With embryolike constructs built entirely from stem cells, researchers can revolutionize our understanding of development. But how close to an embryo is too close? In April, researchers in China ...
The schematic depicts five stages of human implantation: (1) blastocyst differentiation into ICM/TE; (2) apposition and adhesion to luminal epithelium (dependent on L-selectin/ligand); (3) invasion ...
