 | | Invagination of the blastula at a particular point forms the blastopore and signals the development of the gastrula in most metazoa. | | | The blastopore is an opening or pore that develops in the initial ball of cells or blastula from which all Metazoans develop. | | | The blastopore becomes the mouth in the Protostomata and the anus in the Deuterostomata. |

| | The Organizer Experiment: Transplantation of the Upper Lip of the Blastopore |
| | The organizer experiment represents the classical case of a complex induction. | | | The self differentiating transplant and the induced host structures together formed a well integrated set of secondary axial and paraxial structures, with its own polarity and bilateral symmetry, approaching a complete secondary embryo at the ventral region of the host embryo. | | | Using the hair loop, turn them over with very gentle movements, so that the blastopores face upward. |

| | Animals in which the blastopore becomes the mouth are called protostomes; those in which the mouth develops after the anus are called deuterostomes (from the Greek "deutero," meaning second, and "stoma," meaning mouth). | | | The fate of the blastopore has classically been used as the defining characteristic of protostomes and deuterostomes. | | | In protostomes, the blastopore develops into the mouth, and the anus develops from an opening later in development. |

| | blastopore -- Encyclopædia Britannica |
| | The coelom (body cavity) forms from a split in the embryonic mesoderm... | | | During maturation of some animals it evolves into the anus or the mouth; in others it is covered over and contributes to the canal joining the primitive gut with the cavity of the neural tube, the primitive nervous system. | | | The mouth of the Protostomia (proto, “first”; stoma, “mouth”) develops from the first opening into the embryonic gut (blastopore). |

| | We argue that caudal and other genes expressed at the posterior of the Drosophila embryo (fork head, brachyenteron and wingless) constitute a conserved constellation of genes that plays a required role in gastrulation and gut development. | | | Role of caudal in hindgut specification and gastrulation suggests homology between Drosophila amnioproctodeal invagination and vertebrate blastopore. | | | Role of caudal in hindgut specification and gastrulation suggests homology between Drosophila amnioproctodeal invagination and vertebrate blastopore.During early embryogenesis in Drosophila, caudal mRNA is distributed as a gradient with its highest level at the posterior of the embryo. |

| | Keller sandwiches-One of several types of explants of tissue lying immediately animal to the blastopore lip of an early Xenopus gastrula, and including involuting marginal zone, non-involuting marginal zone, and animal cap cells, named for Ray Keller, who devised the technique. | | | In the original Keller sandwich, two such strips of tissue, containing both superficial and deep cells, are placed together such that their deep cells are in contact and their animal and vegetal ends are aligned. | | | The groove presumably results from the invagination produced by apical construction, as well as the basal expansion of the basal ends of the bottle cells, which forces nearby tissue to roll. |

| | BLASTOPORE definition |
| | In some animals, for example chick, invagination occurs without a true blastopore and the site at which the cells move in (primitive streak) may be termed a virtual blastopore. | | | During gastrulation cells on the surface of the embryo move into the interior to form the mesoderm and endoderm. | | | The opening formed by this invagination of cells is the blastopore. |

| | In protostome animals the blastopore become the mouth of the digestive tract, whereas in deuterostome animals the blastopore becomes the anus of the digestive tract. | | | Prior to the embryo stage, it is first a blastula (hollow ball of cells) and gastrula (ball of cells that begins to differentiate into a structure with tissues). | | | We will now go through some of the phyla to illustrate some of these features. |

| | Animals in which the blastopore becomes the mouth are called protostomes; those in which the mouth develops after the anus are called deuterostomes (from the Greek "deutero," meaning second, and "stoma," meaning mouth). | | | In this view, it makes sense to talk about animal evolution being a more or less stately progress from simple to complex; thus, one can label the simple animals, which are at the bottom of the tree, the "lower" metazoans, and the more advanced ones, the "higher" metazoans. | | | Animal Aid campaigns peacefully against all animal abuse, and promotes a cruelty-free lifestyle. |
