What are mesenchymal cells?
Mesenchymal stem cells (MSCs) are multipotent stem cells found in bone marrow that are important for making and repairing skeletal tissues, such as cartilage, bone and the fat found in bone marrow. These are not to be confused with haematopoietic (blood) stem cellsthat are also found in bone marrow and make our blood.

What are epithelial cells?
Epithelial cells are cells that come from surfaces of your body, such as your skin, blood vessels, urinary tract, or organs. They serve as a barrier between the inside and outside of your body, and protect it from viruses. A small number of epithelial cells in your urine is normal.
The only dental epithelial cells present in adult human teeth are the cell rests of Malassez covering the roots as a thin network. They have been suggested to exhibit stem cell properties, but there is no evidence of their capacity to generate dental epithelium.
