The effect of TGF-β1 and PDGF-BB, and their combinations with DNCPs (250 ng/ml) on cell viability in 3 time intervals assessed by MTT cell proliferation assay.
A = 5 ng/mL; B = 10 ng/mL.
aStatistically significant difference at the level P < 0.05 (Tukey’s post-hoc test) compared with the control group (regular medium without DNCPs, TGF-β1 and PDGF-BB; viability 100%).
