The role of tissue that forms between the head and trunk of a fly embryo has been unclear. It turns out that it absorbs forces when nearby cells move and divide. An early fruit-fly embryo comprises a ...

The mystery of early embryonic communication is starting to be unraveled thanks to a new stem cell-based model.

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 ...

Descriptions of the embryo go back at least to the time of Aristotle, but it has only been since the late 19 th century and early 20 th century that advances in experimental approaches allowed ...

Assistant Professor of Obstetrics and Gynecology, School of Medicine, University of Washington Embryonic development, also known as embryogenesis, is a cornerstone in understanding the origins of life ...

Researchers have discovered a key transition in early embryonic development is facilitated by decreasing levels of a viral protein inserted into the DNA of our early animal ancestors. Researchers at ...

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 ...
