Cytotoxicity studies with RAW 264.7 macrophages. (a) Cells were cultured for 24 h on Col or Col-V (20 μg/mL per cm2 VOAsc) scaffolds, stained with Giemsa and photographed. (b) An MTT assay was performed to evaluate cell survival of BMPC growing on Col or Col-V scaffolds. Results represent the mean ± SEM.
