MESENCHYME - 2 reference results
Mesenchyme refers to loosely organized connective tissue present in the embryo regardless of origin. Viscous in consistency, mesenchyme contains collagen bundles and fibroblasts. Mesenchyme later differentiates into blood vessels, blood-related organs, and connective tissues.
Embryonic connective tissue (mesenchyme):
- Consists of loosely-packed, unspecialized cells set in a gelatinous extracellular matrix
- Develops into other types of tissues: connective, bone, cartilage
- Develops into other types of structures and systems: blood cells, endothelial cells, smooth muscle cells, circulatory system, lymphatic system.
All organs in the body contain mesenchyme.
Ectomesenchyme
Ectomesenchyme has similar properties to mesenchyme. The major difference is that ectomesenchyme is usually considered to arise from neural crest cells, which are a critical group of cells that form in the cranial region during early vertebrate development. Thus, ectomesenchyme plays a critical role in the formation of the hard and soft tissues of the head and neck such as bones, muscles and most importantly the branchial arches.See also

- Mesohyl, the gelatinous matrix in sponges, was formerly also called mesenchyme
