Regarding cells cultured with extracted media, obtained as described previously with BC and BC/PHEMA/PEGDA (1 : 3 : 0.05) membranes, no significant differences in proliferation rates were observed among them when we compare with negative control; whereas no significant differences exist in growth rate of cells cultured with BC extracted media, a slightly significant lower growth rate was found in the case of cells cultured in BC/PHEMA/PEGDA (1 : 3 : 0.05) extracted media ( P < 0.05).
