Cell adhesion and proliferation of PDLSCs on non-coated (A, B) and HydroMatrix-coated (C, D) surfaces. Real-time impedance analysis (A, C) were carried out using an xCELLigence system. Cell viability was assessed by WST-1 assay (B, D) at a seeding density of 10,000 cells/well. Values are given as mean ± standard errors of the mean (SEM). *p < 0.05 compared to data gained 24 h after cell seeding
