Figure 4.

in vitro studies showing (A) cell attachment of hMSCs cells after day 1 incubation on CPC and Cu loaded CPC scaffolds showing changes in cell morphology with increased copper amounts in the scaffolds imaged under low mag SEM, high mag SEM, as well as fluorescence microscopy and (B) cell proliferation of hMSCs for day 1, 3, and 7 durations on CPC and Cu loaded CPC scaffolds showing improved cell proliferation with respect to time and no cell proliferation on scaffolds CPC-Cu 3 and CPC-Cu 5 groups. The data are represented mean ± standard deviation (n = 3). The significance of difference p < 0.05 for various groups.
