mesenchyme
Sign in to saveMesenchyme () is a type of loosely organized animal embryonic connective tissue of undifferentiated cells that give rise to many tissues, such as skin, blood, or bone. The interactions between mesenchyme and epithelium help to form nearly every organ in the developing embryo.

Mesenchyme () is a type of loosely organized animal embryonic connective tissue of undifferentiated cells that give rise to many tissues, such as skin, blood, or bone. The interactions between mesenchyme and epithelium help to form nearly every organ in the developing embryo.
==Vertebrates== ===Structure=== Mesenchyme is characterized morphologically by a prominent ground substance matrix containing a loose aggregate of reticular fibers and unspecialized mesenchymal stem cells. Mesenchymal cells can migrate easily (in contrast to epithelial cells, which lack mobility, are organized into closely adherent sheets, and are polarized in an apical-basal orientation).
