Biological assessment of PCL–M polyHIPEs. The metabolic activity of MDA-MB-231 cells via a resazurin reduction assay across 7 days on (A) untreated PCL–M scaffolds (P−) or scaffolds functionalised with air and acrylic acid (AAc) plasma treatment (P+) and (B) preconditioned with fibronectin (N = 3, n = 5, * p < 0.033). (C) Confocal images of MDA-MB-231 cells transduced with mStrawberry following 7 days cultured on PCL–M scaffolds pre-soaked in PBS or fibronectin (scalebar represents 200 μm).
