Characterization of gastric cancer models from different cell lines orthotopically constructed using improved implantation techniques

Figure 2 Macroscopic examination of the primary tumor in the two models. A: The tumor of SGC-7901 shows large volume (9.30 ± 3.62 cm³), irregular lobular shape, and stenosis in the cardia or pylorus; B: The tumor volume of BGC-823 is 1.24 ± 0.73 cm³, with irregular lobular appearance; C: Comparison of primary tumor volume in two models. The difference is statistically significant. ^aP < 0.05, student t test.
