Mesenchyme is a type of animal tissue comprised of loose cells embedded in a mesh of proteins mesenchyme fluid, called the extracellular matrix, mesenchyme. The loose, fluid nature of mesenchyme allows its cells mesenchyme migrate easily and play a crucial role in the origin and development of morphological structures during the embryonic and fetal stages of animal life.

Mesenchyme is an embryonic precursor tissue that generates a range of structures in vertebrates including cartilage, bone, muscle, kidney and the erythropoietic system. Mesenchyme originates from both mesoderm and the neural crest, an ectodermal cell population, via an epithelial to mesenchymal transition EMT. Because ectodermal and mesodermal mesenchyme can form in close proximity and give rise to similar derivatives, the embryonic origin of many mesenchyme-derived tissues is still unclear.

Mesenchyme

Mesenchyme , or mesenchymal connective tissue , is a type of undifferentiated connective tissue. It is predominantly derived from the embryonic mesoderm , although may be derived from other germ layers , e. The term mesenchyme is often used to refer to the morphology of embryonic cells that, unlike epithelial cells , can migrate easily. Epithelial cells are polygonal, polarized in an apical-basal orientation, and organized into closely adherent sheets. Mesenchyme is characterized by a matrix that contains a loose aggregate of reticular fibrils and unspecialized cells capable of developing into connective tissue: bone, cartilage , lymphatics and vascular structures.

Mesenchyme is characterized morphologically by a prominent ground substance matrix containing a loose aggregate of reticular fibers and unspecialized mesenchymal stem cells. The mesenchyme originates from the mesoderm. This "soup" exists as a combination of the mesenchymal cells plus serous fluid plus the many different tissue proteins. Serous fluid is typically stocked with the many serous elements, such as sodium and chloride. The mesenchyme develops into the tissues of the lymphatic and circulatory systems, as well as the musculoskeletal system.

Elsevier Health Sciences. Bodenstein, D. Citation, DOI, disclosures and article data. Development 14, — The focus of mesenchyme research, however, divides between two general interests: the role and expression of mesenchyme-specific genes during development, including pathological processes, and the locations and capabilities of mesenchymal stem cells.

Mesenchyme is a tissue found in organisms during development. It consists of many loosely packed, nonspecialized, mobile cells.

Mapping was according to Bijtel 20 who originally divided the neural plate of stage 16 neurulae along the cranio-caudal axis into 5 rectangular zones. Taken together, these experiments suggest that the posterior neural plate and neural folds region 3 are the main source of tail fin mesenchyme and tail muscle. Epithelial—mesenchymal transition occurs in embryonic cells that require migration through or over tissue, and can be followed with a mesenchymal—epithelial transition to produce secondary epithelial tissues. All animal procedures were performed according to the European Community and local ethics committee guidelines. Article Google Scholar Tucker, A. Center for Biology and Society.
