ABSTRACT
Objective To investigate the the multi-directional differentiation potential between pluripotent of human gingival fibroblasts (HGFs) and human periodontal ligament cells (HPDLCs). Methods HPDLCs and HGFs were obtained from the primary culture. HPDLCs and HGFs at 3rd-4th passage were cultured in osteogenic, adipogenic or chondrogenic me-dium. Cells without differentiation were taken as control. Alizarin red, Alcian blue and oil red O staining were performed to detect osteogenic differentiation, chondrogenic and adipogenic differentiation in vitro, respectively. Reverse transcription polymerase chain reaction (RT-PCR) was applied to examine the expression of osteocalcin (OCN), runt-related transcription factor 2 (RUNX2) and collagen 1 (Col 1), peroxisome proliferator-activated receptor gamma 2 (PPARγ2) and collagen 10 (Col 10). Results HPDLCs and HGFs cultured in osteogenic medium showed massive calicium nodulus at day 28, but HP-DLCs formed more calicium nodulus than those of HGFs. The expressions of OCN, RUNX2 and Col 1 were significantly high-er in HPDLCs than those in HGFs (P<0.05). In chondrogenic medium both cells were found blue deposit at day 14, and the expression of Col 10 was significantly higher in HGFs than that of HPDLCs (P<0.01). Furthermore, in adipogenic medium HGFs showed more lipid-filled droplets stained with oil red O than HPDLCs at day 21. The expression of PPARγ2 was sig-nificantly higher in HGFs than that of HPDLCs (P<0.01). Conclusion HPDLCs has the better potency of osteogenic differ-etiation than HGFs, however, HGFs has the better potency of adipogenic and chondrogenic differentiation.
