How do endodermal cells behave during gastrulation? In this paper, the authors found that a gradient of BMP regulates mesoderm and endoderm convergent extension. Endoderm cells also use the mesoderm and Cxcr4a signalling to guide their movement. The imaging is beautiful!

In this intriguing paper published from the lab of @amartinezarias.bsky.social , they looked at the effects of size on morphology, tissue composition, and gene expression of gastruloid development. They found that AP elongation dynamics is size-dependent! Check it out here:
