BEIJING, Jan. 29 (Xinhua) -- After years of dedicated research, a team of Chinese scientists has unveiled critical mechanisms governing early human embryonic development, offering novel theories and ...

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 ...

Researchers have captured the very first real-time, three-dimensional images and videos of a human embryo implanting into collagen designed to mimic uterine tissue —a key stage in reproduction. The ...

Human fetal tissue research has helped in the development of some vaccines.

Ancient viruses are embedded everywhere in the human genome. Estimates range, but it's thought that about eight percent of the human genome could be made up of these ancient retroviruses, which are ...

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 - ...

A new study using stem cell-based models has shed new light on how the human embryo begins to develop, which could one day benefit the development of fertility treatment. The study led by at the ...

A team of scientists has just gotten a closer peek into one of the earliest and most fundamental steps of creating a human life. Research out today highlights how they captured—for the first ...

Long before human bone marrow takes over the task of producing blood, discrete waves of blood cell production occur in the developing embryo. Miriana Dardano, a postdoctoral researcher in Zweigerdt’s ...
