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 ...

Scientists have developed a new human-based endometrial model to study embryonic implantation in the early stages of ...

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 - ...

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 ...

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 ...

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 ...

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 ...

Scientists have gotten an unprecedented look at how the human embryo implants in a uterus. They did this by creating very primitive, womb-like environments in the lab. "This is really important work ...
