Bmi1 Severs as a Potential Tumor-Initiating Cell Marker and Therapeutic Target in Esophageal Squamous Cell Carcinoma

Figure 3

Depletion of Bmi1+ cells led to decreased proliferation and increased apoptotic phenotype in ESCC. (a) Bmi1CreER;RosatdTomato;RosaDTA mice were compared with the control in the malignant degree of ESCC. (b) Apoptosis of the Bmi1CreER;RosatdTomato;RosaDTA group was higher than that of the control group under the TUNEL test. Red indicates apoptotic cells. (c) Ki67 signal was reduced in ESCC without Bmi1+ cells, and Ki67 signal was represented by black. , , and . Scale bars are 100 μm.
