Proliferation of cells exposed to conditioned media. Plots depict fold increase in number of mouse mesenchymal stem cells normalized to initial seeding density as a function of gel soaking time and gel type used to condition media. A) Cumulative scheme: gels were soaked in media such that they could continuously release soluble products up to the time points. B) Snapshot scheme: gels were soaked in media in culture conditions such that the gels could release products in sequential three day periods. Error bars represent S.D. (n=5) and statistical significance (*,p<0.05) was determined by two-way ANOVA with a Tukey post-hoc test. # marks p<0.05 relative to no gel control in snapshot case
