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 ...

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 ...

However, gastrulation, the period beyond this cutoff, represents when the embryo begins to form the eventual body plan, making it an interesting stage to understand early organogenesis. “We’ve just ...

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 ...

During the first 72 hours in particular, extracellular vesicles—nanoparticles enclosed in cell membranes—play a significant ...
