Kangfuxin solution alleviates esophageal stenosis after endoscopic submucosal dissection: A natural ingredient strategy

Figure 5 Phenotyping of isolated primary esophageal cells and dose determination of Kangfuxin solution. A: Representative images of immunofluorescence staining of vimentin and cytokeratin, magnification 400 ×; primary cells exhibited specific expression of vimentin while showing minimal expression of cytokeratin protein; B: The proliferation rate of primary esophageal fibroblasts after stimulation with different concentrations of Kangfuxin solution using the CCK-8 assay. Data are presented as mean ± SE. ^gP < 0.001 vs the zero tube.
