Human bodies have to be built from a single egg cell that's fertilized by a sperm cell. Many rounds of cell division occur as the body is developing, and it seems that there are plenty of chances for ...

For the first time, scientists have used human cells to make structures that mimic the earliest stages of development, which they say will pave the way for more research without running afoul of ...

When Berna Sozen, PhD, assistant professor of Developmental Stem Cell Biology at Yale, was in her first weeks of pregnancy, she couldn’t help but wonder about what exactly was going on in the “black ...

Cells in culture typically form continuous sheets, like skin. But in 2017, bioengineer Jianping Fu realized that if he cultured human stem cells in a 3D scaffold, they would spontaneously organize ...

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 used naïve pluripotent stem cells to create an embryo model that looks and acts like a natural human embryo. They say it’s an ethical way of gaining a better understanding of ...

Moira Gleason is a Daily Signal journalism intern. When Donald Trump signed an executive order aimed at lowering costs for and reducing barriers to in vitro fertilization last month, that renewed the ...

Researchers have discovered a potential 'pause button' in the earliest stages of human development. Whether humans can control the timing of their development has long been debated. The new study ...
