Researchers have developed a new stem cell model of the mature human amniotic sac, which replicates development of the tissues supporting the embryo from two to four weeks after fertilization. This is ...

University of Cambridge scientists have used human stem cells to create three-dimensional embryo-like structures that replicate certain aspects of very early human development—including the production ...

A research team led by Professors Yixuan Wang and Shaorong Gao from the School of Life Sciences and Technology at Tongji University has made significant progress in understanding early human embryonic ...

A recent study in Advanced Science presents a method for studying early human embryology by bioprinting epiblast-like structures from human-induced pluripotent stem cells (hiPSCs). The model forms a ...

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 ...

Bioengineering researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have developed a soft, thin, stretchable bioelectronic device that can be implanted into 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 ...

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 - ...
