The cells were extracted from the dental pulp of two canine cadavers, with approximately ten months of age, which died due to automotive trauma. After three subcultures, cell viability evaluation was performed by Neubauer chamber quantification. Neural differentiation was induced in neurobasal culture medium (Gibco ™), with cells adhered to the plastic or suspended in agarose-treated plates. After seven and 14 days in inducer culture, morphology and immunophenotypic profile were observed using flow cytometry and fluorescent immunocytochemistry. At 14 days the cells had a high degree of expression for anti-nestin and anti-glial fibrillary acidic (anti-GFAP) markers. Previously, an average of 18x10⁶ undifferentiated viable cells from the pulp tissue were obtained on the 25th day. It is suggested that the undifferentiated canine pulp stem cells present satisfactory differentiation indices in neural progenitor cells, adhered or suspended in culture. The dental pulp of deciduous canine teeth provides viable undifferentiated cells in adequate quantity.</p><p></p>
