In vivo (Athens, Greece) 2015 May-JunAs already described in previous studies, neural crest stem cells (NCSCs) can be found in adult human dental pulp. The present study investigated the methodology for enrichment and differentiation-induction of the above mentioned cells. Dental pulp was extracted from human wisdom teeth of four patients and subsequently cultured as explants on fibronectin-coated plates in neurobasal medium supplemented with B27, basic fibroblast growth factor (bFGF), epidermal growth factor (EGF), insulin, l-glutamine and neuregulin-β1. The cells were then characterized by immunofluorescence, while their differentiation-potential was tested by the attempt to induce cells into different lineages, i.e. osteogenic, melanocytic and glial. The enriched cell population expressed nestin, CD271 and SOX10, which are well-known markers for NCSCs. Consequently, the cells were successfully induced to differentiate into osteoblasts, melanocytes and Schwann cells, expressing the corresponding differentiation markers. Human adult dental pulp contains a population of stem cells with neural crest ontogeny, which can thus be recruited for multiple regenerative therapies.
