Study Notes
Embryonic Mesenchyme and Connective Tissue
- Cells originating from embryonic mesenchyme include bone cells, cartilage cells, and fat cells.
- The main component of the ECM produced by mesenchymal cells is collagen.
- Mesenchymal stem cells are considered undifferentiated cells in connective tissue.
- The function of mesenchymal cells in connective tissue is to produce the ECM and provide structural support.
Development of Embryonic Mesenchyme
- Embryonic mesenchyme develops from the mesoderm layer of the embryo.
Origin of Connective Tissue
- All connective tissue originates from mesenchymal cells.
- The origin of all connective tissues is the mesoderm layer of the embryo.
