Reduction of PrestoBlue reagent as a correlate of cell viability (a, b) and cell proliferation as evaluated via PicoGreen assay (c, d) in the indirect and direct cell culture setting during the incubation period (D1-D21). Values are normalized to the control group (indicated by the dotted line) and shown as means with standard deviation. (*) indicates significant difference between the BG groups.
