·来源： 间充质 mesenchyme
Connective tissue formed by the cells of the mesoderm during embryological development,known as mesenchyme that the connective tissues of the body develop.Mesenchyme is composed of mesenchymal cells and amorphous matrix.Mesenchymal cell is astral in shape,with a large nucleus and an apparent nucleolus.Its cytoplasm is weakly basophilic.
The cell is lower degree in differentiation,but it has the strong ability of proliferation and differentiation,and can differentiate into connective tissue cells,endothelial cells,and smooth muscle fibers.The other component of the mesenchyme is aphormous ground substance.
