FIG. 5.

Data on in vitro degradation of scaffold. (A) Change in molecular weight (weight average [Mw] and number average [Mn]) of polymer suspended in culture medium with or without fibroblast after different periods. (B) Tensile strength and percent elongation of hybrid scaffolds suspended in culture medium with or without fibroblast after different periods. Elongation was higher for cell-grown samples but was not statistically significant. Mechanical testing of cell-free scaffolds was not possible after 40 d of immersion in the medium because they were found to have lost the required dimension due to shrinkage. Data presented is average±SD (n=5). *p<0.05. The periods of analysis are marked in the x-axis.
