A MedUni Vienna study team led by geneticist Markus Hengstschläger has used a stem cell model to model the earliest stages of embryonic development and to characterize the membrane that surrounds the ...

Egg yolk may appear runny and uniform, but on the nanoscale, it is one of the most crowded biological fluids in nature. Packed with proteins and fats, it serves as a dense storage reservoir for a ...

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 ...

The early beginnings of an embryo as it transforms from a clump of cells to a tiny human is a bit of a mystery — scientifically speaking. We know many of the broad strokes, but there are a lot of ...

Scientists have uncovered a new quality control system that removes damaged cells from early developing embryos. Scientists studying gene activity data of the early human embryo have discovered an ...

Week 3 of pregnancy is a critical stage when the embryo begins to grow rapidly. During this week, cells divide at an astonishing rate, laying the foundation for all future tissues and organs. This ...

Healthy development The researchers found that higher variability in cell division leads to a more optimal arrangement of cells within the embryo, which promotes healthy development. "Our work ...

LONDON (Reuters) - A new high-powered microscope has allowed scientists to watch a zebrafish develop from a single cell into an embryo with a beating heart, the first time this has been possible in ...

Passing on fundamental life lessons from parent to offspring is not unique to humans and animals. Ferns do it too. Not with ...

Add Yahoo as a preferred source to see more of our stories on Google. As an evolutionary biologist whose career has focused on how embryos develop in a wide variety of species over the course of ...
