The behavior of CFDA-SE labeled 3T3 fibroblasts seeded onto EPPOMaC scaffolds. (A) Initially, a light density of cells located along the scaffold surface could be seen (day 2). (B) By day 7, the cell density elevated as evident by dense cell clusters located on the scaffold surface. (C) After 14 days, the cells could be observed growing along the edge of surface pores and had migrated into the interior of the scaffold (scale bar = 50 μm).
