Long before human bone marrow takes over the task of producing blood, discrete waves of blood cell production occur in the developing embryo. Miriana Dardano, a postdoctoral researcher in Zweigerdt’s ...

In vertebrates, the skeleton of different regions of the body arises from different precursor cells. Researchers at the University of Basel have now discovered that these skeletal cells do not just ...

A study conducted by researchers at Baylor College of Medicine and collaborating institutions reveals the molecular events leading to osteogenesis imperfecta type V, a form of brittle bone disease ...

What do the earliest stages of a pregnancy look like? Embryonic development has been extensively studied, but most of our knowledge of the earliest stages of a growing baby come from stationary ...

The earliest days after fertilization, once a sperm cell meets an egg, are shrouded in scientific mystery. The process of how a humble single cell becomes an organism fascinates scientists across ...

Using CRISPR-based engineering methods to prompt stem cells to organize into embryo-like structures, scientists were able to create 'programmable' cellular models of embryos without ever experimenting ...

A gene that turns on very early in embryonic development could be key to the formation of the placenta, which provides the developing fetus with what it needs to thrive during gestation.
