Fig. 3From: Sustained delivery of siRNA/PEI complex from in situ forming hydrogels potently inhibits the proliferation of gastric cancerDifferent release profiles of siRNA under different conditions. Cells were exposed to no siRNA, siRNA only in the hydrogels, siRNA present in the media, or siRNA in hydrogels with the addition of PEI. RT-PCR analysis was performed. Values are the means ± SD of 3 wells. Id1 mRNA levels in the treated-cells were normalized to the control group cellsBack to article page
