Zebrafish Development

Zebrafish Development The teleost fish Danio rerio is commonly known as the zebrafish. It is a common small‐bodied tropical, freshwater species originally from South Asia.  The fish is a part of the Cyprinidae family, which includes carps, true minnows, barbs and related genera. The Danio genus (formerly Brachydanio) contains more than 40 related species along with the zebrafish (Danio … Read more Zebrafish Development

Gastrulation- Process, Consequences

The most characteristic event occurring during the third week of gestation is gastrulation. Gastrulation is a formative process by which the three germ layers, which are precursors of all embryonic tissues, and the axial orientation are established in embryos. During gastrulation, the bilaminar embryonic disc is converted into a trilaminar embryonic disc. Extensive cell shape … Read more Gastrulation- Process, Consequences

Epiblast- Development and Significance

Epiblast- Development, and Significance As implantation of the blastocyst occurs, morphologic changes in the embryoblast produce a bilaminar embryonic disc composed of epiblast and hypoblast cells. Epiblast is derived from the inner cell mass and lies above the hypoblast.  The epiblast is thus, one of the two distinct layers arising from the inner cell mass … Read more Epiblast- Development and Significance

Human Embryogenesis

Human Embryogenesis Human embryogenesis refers to the development and formation of the human embryo. It encompasses the first eight weeks of development after fertilization, in which a single cell formed at fertilization turns into an organism with a multi-level body plan. It is characterized by the process of cell division and cellular differentiation that occurs during the early stages … Read more Human Embryogenesis
