    Abstract:
    OBJECTIVE: To increase the success rate of primary culture of human periodontal ligament fibroblasts (HPLF), and to establish an experimental model for studying HPLF in vitro. METHODS: The primary cells were isolated from human periodontal ligament by explants with enzymatic digestion method. Morphological analysis and immunocytochemical staining were used to characterize the cell lineage, and growth curve assay to evaluate the biological features of HPLF. RESULTS: The success rate of primary culture of HPLF was 77.8%. Cultured cells were spindle-shaped, and had a positive reaction to antibodies against vimentin, and a negative reaction to antibodies against keratin. Their morphological and biological characteristics were similar to those of typical HPLF. Growth of HPLF obtained by this method was satisfactory. CONCLUSION: The success rate of primary culture of HPLF is significantly increased by explants combined with enzymatic digestion. The method is simple and feasible.
