Feathers are complex skin structures, and their evolutionary beginnings are still a subject of scientific debate. Scientific ...

Closely studied, stem cell lines might give scientists new clues about the growth factors that drive tissue differentiation from the earliest embryonic stage forward. This would permit new ...

So, Haeckel proposed, by examining the development of an embryo you could read its entire evolutionary history in the transition from one stage to another. In fact, this isn't strictly true ...

Extracellular nanoparticles play an important role in cell differentiation and the coordinated growth of organs in the embryonic phase. These also include something known as extracellular vesicles ...

Now - the clever bit. The cells on the inside layer of this very early embryo can make all of the cell types needed in your body. They're called stem cells. The stem cells continue to divide by ...

Synchronizing preimplantation embryo development up to the blastocyst stage with uterine differentiation to the receptive state is an absolute requirement for successful implantation. Molecular ...

Vaping during pregnancy is becoming more common, but its impact on early human development is not well understood. A new study by scientists at the University of California, Riverside, now reports ...
