WebSep 4, 2024 · Figure 23.3. 3: Blastula and Gastrula. The blastula is composed of one layer with a Blastocoel inside. Some cells of the outer layer fold into the Blastocoel to create a Blastopore. This invagination also gives rise to three germ layers. This diagram is color-coded. Ectoderm, blue. Endoderm, green. WebThe new space that forms is the archenteron, or “first gut.” The opening into the archenteron is the blastopore. Recall that in deuterostomes, the blastopore becomes the anus and the mouth (the second opening) forms opposite it. The outer layer of cells is now ectoderm, and the wall of the archenteron is endoderm and future mesoderm.

In the context of an embryo, an ‘organizer’ refers to a group of cells that harbour the ability to instruct fates and morphogenesis in surrounding cells, steering their development into specific organs and tissues ( Anderson et al., 2016 ). As a result, organizers can position specific tissues and organs relative to each other.
