Level of cell metabolic activity in terms of fluorescence values at Day 3 and Day 7 during cell culture. The level of cell metabolic activity of fibroblasts cultured on glass coverslips and on PCL A and PCL B scaffolds were compared between each other. Only growth media with no cells or biomaterials was used as the negative control and fibroblasts cultured directly over the culture well-plate were used as the positive control so as to identify the range of fluorescence.
