MKI67 and neoplasm: Representative HT‐29 sections encompassing entire tumors through their maximum diameter show that cleaved caspase‐3 (cell death marker) is more widely detected in the NVP‐Iso‐treated tumor compared to the control (representative tumor, Fig. 7F), and that the cell replication marker Ki67 is more widely detected in the control compared to the NVP‐Iso‐treated tumor (same representative tumor, Fig. 7G, magnified panels a and b).
