(a) Scanning electron microscopy (SEM) photos of dermal scaffolds. (b) Matrix contraction of contractile collagen gels (CCG), Integra (I), Matriderm (MD), and Smart Matrix (SM). (c) Cell viability and proliferation by alamarBlue assay of monolayer control (C), contractile collagen gels (CCG), Integra (I), Matriderm (MD) and Smart Matrix (SM) at days 2 and 7 of culture (*C at day 2 significantly higher, p<0.05, than CCG, I, and MD; #C at day 7 significantly higher, p<0.05, than CCG and MD; +SM at day 2 significantly higher, p<0.05, than MD; significant increase in alamarBlue activity, p<0.05, between days 2 and 7 for C, CCG, MD, and SM).
