MKI67 and cancer: Some of the Ki-67+ cells, indicative of proliferating cancer cells, were overlapped with the NF-SION+ cells as presented in Fig. 9A, however, further examination is required because they might be proliferating inflammatory cells (Ki-67+ and CD11b+ cells) as confirmed by dual staining with CD11b monocytes/macrophages marker in Fig. 10B.
