Comparing the cell growth of A fibroblast monocultures, B keratinocytes monocultures and C fibroblast-keratinocyte co-cultures in 3D wound healing constructs at days 1, 3, and 7 measured by alamarBlue^® (n = 9). The x-axis shows the fibrin-bead and wound concentrations in mg/mL (when present; see illustration insert) and the thrombin concentration used for polymerization in units/mL. The collagen concentration was 2.4 mg/mL. Cell growth data is presented as a percentage of day 1 and error bars represent standard deviation. "Asterisks" indicates p < 0.05 when comparing cell growth between timepoints
