Dental pulp stem cells
Dental Pulp Stem Cells, or (DPSCs) are multipotent stem cells that have the potential to differentiate into a variety of cell types.
More recently a subpopulation of dental pulp stem cells has been described as human Immature Dental Pulp Stem Cells (IDPSC).[1]
Definition
Dental pulp is the soft living tissue inside a tooth. Stem cells are found inside the soft living tissue.[2] Scientists have identified the Mesenchymal type of stem cell inside dental pulp. This particular type of stem cell has the future potential to differentiate into a variety of other cell types including:
History
- 2003 NIH announces discovery of DPSCs by Dr. Songtao Shi [2]
- 2006 IDPSC Kerkis reported discovery of Immature Dental Pulp Stem Cells (IDPSC),[1] a pluripotent sub-population of DPSC using dental pulp organ culture.
- 2007 DPSC 1st animal studies begin for bone regeneration.[6][7]
- 2007 DPSC 1st animal studies begin for dental end uses.[10][11]
- 2008 DPSC 1st animal studies begin for heart therapies.[3]
- 2008 IDPSC 1st animal study began for muscular dystrophy therapies.[5][5]
- 2008 DPSC 1st animal studies begin for regenerating brain tissue.[4]
- 2008 DPSC 1st advanced animal study for bone grafting announced. Reconstruction of large size cranial bone defects in rats.[9]
- 2010 IDPSC 1st human trial for cornea replacement
