Mesodermal origin

See Article History. Mesoderm, the middle of the three germ layers, or masses of cells (lying between the ectoderm and endoderm), which appears early in the development of an animal embryo. In vertebrates it subsequently gives rise to muscle, connective tissue, cartilage, bone, notochord, blood, bone marrow, lymphoid tissue, and to the epithelia. The origin of extra-embryonic mesoderm (EEM) has been extensively discussed in the literature. This mesoderm lies outside the embryo, associated with fetal membrane and placenta development. This mesoderm formed at gastrulation along with the embryonic mesoderm from the proximal side of the primitive streak mesoderm (n.) middle germinal layer of the three-layered embryo of a metazoic animal, 1858, from French mésoderme or German Mesoderm, literally middle skin, coined by German physician Robert Remak (1815-1865) from meso- middle + Greek derma skin (see -derm ). Related: Mesodermal; mesodermic

mes·o·derm. The middle of the three primary germ layers of the embryo (the others being ectoderm and endoderm); mesoderm is the origin of connective tissues, myoblasts, blood, the cardiovascular and lymphatic systems, most of the urogenital system, and the lining of the pericardial, pleural, and peritoneal cavities mesodermal musculature—epithelial or mesenchymal origin Basically, mesoderm forms either by direct transformation of portions of the epithelium of the archenteron into the mesothelial mesoderm or by immigration of individual cells from the endodermal blastoporal region or other regions of the archenteron ( Fioroni, 1992 ; Gilbert and Raunio, 1997 ) Introduction. Mesoderm—from the Greek μ σo-ζ (middle) + δ ρμα (skin). This simple descriptive name belies a multifaceted role for the middle of the three embryonic germ layers. It is the youngest layer, in evolutionary terms, and is a hallmark of the development of all complex metazoans The embryonic origin of vertebrate cranial skeleton (mesoderm and neural crest), as well as trunk endoskeletal elements such as vertebra (mesoderm) has been well studied in tetrapods6,7,8,9,10,11,14. In contrast, the origin of trunk exoskeleton was still enigmatic Mesoderm definition is - the middle of the three primary germ layers of an embryo that is the source of many bodily tissues and structures (such as bone, muscle, connective tissue, and dermis); broadly : tissue derived from this germ layer

Mesoderm definition, the middle germ layer of a metazoan embryo. See more mesoderm. [ mĕz ′ə-dûrm′ ] The middle of the three primary germ layers of the embryos of vertebrates and other complex animals. In vertebrates, the mesoderm gives rise to the muscles, bones, cartilage, connective tissue, blood, blood and lymph vessels, dermis, kidneys, and gonads. The mesoderm develops during gastrulation from either the ectoderm. Here we determine the embryonic origin of scales and fin rays of medaka (teleost trunk exoskeletons) by applying long-term cell labelling methods, and demonstrate that both tissues are mesodermal.

The three germ layers in vertebrates are particularly pronounced; however, all eumetazoans (animals more complex than the sponge) produce two or three primary germ layers.Some animals, like cnidarians, produce two germ layers (the ectoderm and endoderm) making them diploblastic The possibility is raised that common mechanisms of axial specification may underlie the initial appearance of segmental patterning in both neural and mesodermal layers during gastrulation. Implications of these conserved patterns for understanding the phylogenetic origin of the vertebrate head are briefly discussed
