Optical redox ratio correlated with osteogenic markers. Optical redox ratio correlated with (a) ACTA2, (b) RHOA, (c) TGFβR1, (d) OPN, (e) OCN and (f) RUNX2 fold change for VIC cultures for days 1 through 28 under quiescent or osteogenic conditions on compliant or stiff substrates. Spearman’s Rank correlation coefficient is denoted as (Sp ρ).
