Fig. 1From: Porphyromonas gingivalis predicts local recurrence after endoscopic submucosal dissection of early esophageal squamous cell carcinoma or precancerous lesionRepresentative images of immunohistochemical staining and RNA in situ hybridization of P. gingivalis in esophageal tissues. A-E Immunohistochemical staining of P. gingivalis in normal epithelium and different lesions of esophagus. F RNA in situ hybridization (RNAscope) detection of P. gingivalis in ESCC tissues. N, Normal esophageal epithelium; HGD, High grade dysplasia; m2 ESCC, ESCC invading the lamina propria; m3 ESCC, ESCC invading the mucularis mucosa; sm1 ESCC, invading the submucosal layer less than 200 μm; RNAscope, RNA in situ hybridizationBack to article page
