Proliferation of MCF7s on hydrogel scaffolds. A. PEG6 resulted in a significant 1.5 fold change (normal to col I veh) in proliferation between vehicle and 1nM E2 treatment. No significant fold change on PEG8 (1.4), col I (1.0) or col I + mat (1.1). Individual data points represent one technical replicate from two independent experiments. B. CV inter-experimental values of proliferation fold-change normal to col I vehicle. N=5 replicates in two independent experiments.
