MTT assay of NIH3T3 fibroblasts cultured on AADP cryogels.

<p>Fibroblasts cultured on tissue culture polystyrene (TCPS) plates have served as controls. The fibroblasts in cryogel sections have recorded relatively low levels of metabolic activity during the first few days as compared to the controls. From day 6 onwards, cryogels have displayed good levels of cell metabolic activity whereas controls have recorded a significant decline in cell activity. This indicates the ability of cryogels to offer high surface area for the growing cells as compared to 2-D controls and further demonstrates their support for cell growth and viability.
