We all start our lives as symmetric balls of cells. In humans, during the first few weeks after fertilization, embryonic ...

The Caltech team observed the vast reorganization and migration of cells that occurs during gastrulation in Drosophila, the fruit fly. During gastrulation, a single-layered tube of cells collapses ...

Gastrulation occurs according to a series of movements defined by their morphogenetic outcome; emboly, epiboly, and convergence and extension.

New insights into the way cells break away from a tissue during embryonic development may also shed new light on the same process in the context of cancer metastasis.

Using chicken eggs and a state-of-the-art imaging device which can reveal how cells move in three dimensions, the researchers demonstrated a key difference in the way gastrulation occurs between ...
