There are mesenchymal stem cells (MSCs) in dental pulp. I have not studied them myself; however, they are reportedly similar to bone marrow MSCs. We bank all the nucleated cells in the bone marrow for two reasons: 1) there are high numbers of MSCs and hematopoietic stem cells (which build blood and immune cells), as well as endothelial progenitor cells (which build vasculature) and others such as marrow stromal cells, pericytes, etc, and 2) most trials employ bone marrow-derived MSCs. The significantly higher numbers are an advantage from an expansion standpoint, and the diversity of cells for applications. Still, having your young biology from your teeth (as long as the cryopreservation is done properly) is an asset, IMO.
