Ingrowth and viability of fibroblasts in the pores of the porous CMC-PEO gel films fabricated by gas-forming of 150–180 μm ammonium bicarbonate particles at the concentrations of either 12% (A, E, I) or 18% (B, F, J); 250–350 μm ones with either 12% (C, G, K) or 18% (D, H, L) and their staining with H&E (E, F, G and H) and MT (I, J, K and L). In vitro cultures of the samples lasted for 35 d and observed by fluorescence (A-D) and light (E-L) microscopy.
