Inhibitory effect of CXB on OSCC tumour growth, migration and invasion in an in vitro model. (A) MTT-based cell viability assay, (B) immunoblotting of PCNA, (C) ICC-IF of Ki-67 (Ki-67 and DAPI showed green and blue fluorescence, respectively), and (D) cell migration ability was determined by the scratch (also refer Supplementary Fig. 2) and transwell assays, and invasion was analysed using a matrigel-transwell assay.
