ABSTRACT
Objective:
To study the effects of PRF and recombinant hPDGF-AB,TGF-β1 and VEGF on the proliferation and adhe-sion of rat adipose tissue-derived stem cells(ADSCs)in vitro.Methods:
ADSCs were cultured with PRF membrane and various do-ses of PDGF-AB,TGF-β1 and VEGF,cell adhesion was examined by adhesion assay after 2 culture,cell proliferation was examined by CCK-8 kit after 1 -7 d culture.Results:
Cell adhesion assay showed that the adhesive numbers of rat ADSCs in PRF group were significantly higher than those in the negative group(P 0.05).The adhesive numbers of the ADSCs treated by VEGF or TGF-β1 at different concentrations showed significant difference(P <0.05).CCK-8 kit assay showed that at different time points, the A values of ADSCs in PRF group were significantly higher than those of the negative control group(P <0.05).The A values of ADSCs in VEGF or PDGF-AB groups at different concentrations showed significant difference(P <0.05).The A values of rat AD-SCs in TGF-β1 group at different concentrations were lower than those in the negative control group(P <0.05).Conclusion:
PRF as a combination of growth factors may stimulate the proliferation and adhesion of rat ADSCs in vitro.PDGF-AB and VEGF may stim-ulate the proliferation of rat ADSCs.TGF-β1 and VEGF may stimulate the adhesion of rat ADSCs in a dose-response manner to some degree.
