The blastula continues to develop, eventually forming a structure called the gastrula. During the process of gastrulation, cells start to move to the interior of the blastula and the three germ ...

Five stages of embryonic development (cleavage, blastula, gastrula, eyed stage, and heart-beating stage embryos corresponding to 7, 14, 20, 26, and 31 days post-spawning) were chosen and exposed to ...

A predatory gastrula leads to symbiosis-independent settlement in Aiptasia. Proceedings of the National Academy of Sciences, 2023; 120 (40) DOI: 10.1073/pnas.2311872120 ...

We identified CHOP transcripts in early blastula Xenopus embryos by RT–PCR methods. CHOP is weakly expressed from fertilized egg to early gastrula (stage 1 to stage 10).

The University of Chicago Press publishes more than 90 scholarly journals that cover a wide range of disciplines, from the humanities and the social sciences to the life and physical sciences. In ...

To investigate whether haematopoietic and endothelial cells arise from a common progenitor, individual cells within the ventral portion of gastrula-stage zebrafish embryos were labelled via laser ...

In most mammals, including humans, the structure formed next is the blastocyst, a mass of inner cells that are distinct from the blastula. The next stage of embryogenesis is formation of the gastrula.
