Isolation and Characterization of Human Dental Pulp Stem Cells Derived from Dental Pulp of Permanent Teeth.

ABSTRACT

Dental pulp stem cells (DPSCs) are a promising alternative to the source of mesenchymal stem cells (MSCs), as they are readily available in minimally invasive procedures compared to more invasive methods associated with harvesting other MSCs sources. Despite the encouraging pre-clinical outcomes in animal disease models, culture-expanding procedures are needed to obtain a sufficient number of MSCs required for delivery to the damaged site. However, this contributes to increasing regulatory difficulties in translating stem cells and tissue engineering therapy to clinical use. Moreover, discussions continue as to which isolation method is to be preferred when obtaining DPSCs from extracted molars. This protocol describes a simple explant isolation technique of human dental pulp stem cells from the dental pulp of permanent teeth based upon the plastic adherence of MSCs and subsequent outgrowth of cells out of tissue fragments with high efficacy.
