Scientists found that embryonic skin cells “whisper” through faint mechanical tugs, using the same force-sensing proteins ...

Like all complex organisms, every human originates from a single cell that multiplies through countless cell divisions. Thousands of cells coordinate ...

A study by WEHI scientists has shed new light on one of the most fundamental mysteries of biology: how cells divide and grow ...

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 ...

Embryo models are getting remarkably realistic.The little clump of cells looked almost like a human embryo. Created from stem cells, without eggs, sperm, or a womb, the embryo model had a yolk sac ...

Scientists have discovered a kind of “pause button” in early human development. This biological mechanism has long been known in other mammals, but its discovery in humans could aid IVF ...

The first four weeks of human embryo development is when the embryo makes all of its organs. The rest is just growth. During this period it’s just impossible to obtain samples. It’s too early.

Early human development is a complex, multistep process that’s even more complicated to study in the lab. Models made from stem cells avoid some of the trouble with using real human embryos.
