FIG. 7.
Collagen content of PCL/ECM constructs both before (cellular) and after (devitalized) devitalization. PCL/ECM scaffolds were generated for 7, 14, or 21 days of culture with five different chondrocyte to MSC ratios. The DNA content for cellular PCL/ECM constructs, included here for comparison to determine the effect of devitalization, originally appeared as data represented by the 35,000-cells/scaffold seeding density in Figure 8 of Levorson et al.21 Data are presented as mean±standard deviation for (n=4). Statistical significance is indicated by the symbols defined in Table 2 (p<0.05).
