Scientists revise the current textbook knowledge about gastrulation, the formation of the basic body plan during embryonic development. Their study in mice has implications for cell replacement ...

Gastrulation is a process common to nearly all metazoan organisms during which an embryo with distinct tissue layers develops out of a seemingly unstructured assembly of cells referred to as 'blastula ...

Researchers offer a phylogenetic and ontogenetic overview of the primitive streak and its role in mediating amniote (vertebrate animals that develop on land) gastrulation, and discuss the implications ...

Figure 1: Cell movements and behaviours during primitive streak formation. First, we analysed the frequency and orientation of mitoses. Cell divisions are uniformly distributed across the image field ...

In a recent study published in the Cell journal, researchers showed that post-gastrulation synthetic embryos (sEmbryos) could be synthesized outside the uterus using mouse naïve embryonic stem cells ...

Platelet-derived growth factor (PDGF) signaling is essential for processes involving cell motility and differentiation during embryonic development in a wide variety of organisms including the mouse, ...

This study documents evolutionary modifications in mechanisms of gastrulation in Heliocidaris erythrogramma, an echinoid with lecithotrophic larvae. Radially symmetrical cell rearrangements and ...

Growing up from embryo to finished animal is a complex business, even for the simplest of creatures. New movies capture the complex dance of migrating cells involved in new, beautiful detail. The ...

Gastrulation is the formation of the three principal germ layers - endoderm, mesoderm and ectoderm. Understanding the formation of the basic body plan is not only important to reveal how the ...

In their publication in Science, Professor Guojun Sheng (Kumamoto University, Japan), Professor Alfonso Martinez Arias (Universidad Pompeu Fabra, Spain) and Professor Ann Sutherland (University of ...
