Silicone-covered biodegradable magnesium stent for treating benign esophageal stricture in a rabbit model

Figure 4 Biological safety evaluation of the magnesium-silicone material by testing the impact on proliferation of human smooth muscle cells. Smooth muscle cells were cultured in the presence and absence of silicone-magnesium gel, and cell proliferation was assayed at 1, 3, 6, and 9 d after culturing (n = 3 for each group at each time point). Control, cultured without silicon-magnesium gel; Mg-silicone, cultured with silicone-magnesium gel.
