Higher Molecular Weight Polyethylene Glycol Increases Cell Proliferation While Improving Barrier Function in an In Vitro Colon Cancer Model

Figure 1

PEG 8000 increases proliferation of Caco-2. Proliferation of cells on the scaffold was observed using MTT proliferation assay as described in Methods. Higher molecular weight PEGs, 8000 and 20,000, increased proliferation regardless of bacterial infection. Maximum proliferation was noted when cells were treated with HS4 and PEG 8000. Standard Student’s -test was applied to the samples and were obtained for samples treated with PEG 8000 and HS4 indicated by an asterisk (*).
