Abstract

Dental pulp stem cells (DPSCs), originating from neural crests, can be found within dental pulp. Up to now, it has been demonstrated that these cells are capable of producing bone tissue, both in vitro and in vivo and differentiate into adipocytes, endotheliocytes, melanocytes, neurons, glial cells, and can be easily cryopreserved and stored. Moreover, recent attention has been focused on tissue engineering and on the properties of these cells. In addition, adult bone tissue with good vascularisation has been obtained in grafts. The latest use in clinical trials for bone repair enforces the notion that DPSCs can be used successfully in patients. Therefore, their isolation, selection, differentiation and banking is of great importance. The isolation and detection techniques used in most laboratories are based on the use of antibodies revealed by flow-cytometers with cell sorter termed FACS (fluorescent activated cell sorter). In this report, we focus our attention on the main procedures used in the selection of DPSCs by flow cytometry, cell culture, freezing/thawing, cell cycle evaluation, histochemistry/immunofluorescence and differentiation of DPSCs. In addition, new methods/protocols to select and isolate stem cells without staining by fluorescent markers for implementation in biomedical/clinical laboratories are discuss. We emphasize that the new methods must address simplicity and short times of preparation and use of samples, complete sterility of cells, the potential disposable, low cost and complete maintenance of the viability and integrity of the cells with real-time response for subsequent applications in the biomedical/clinical/surgical fields.
