Combined treatment of PB and PF inhibited the proliferation and colony formation of TSCC cells. (a) Results of the Edu assay demonstrated the inhibited proliferation of Cal27 and Cal27/CDDP cells following the treatment with PB and/or PF. (b-c) Histogram of Edu fluorescence in Cal27 and Cal27/CDDP cells. (d) Colony formation of Cal27 and Cal27/CDDP cells following the treatment with PB and/or PF. (e-f) Histogram of numbers of colonies of Cal27 and Cal27/CDDP cells. Independent biological experiments were repeated three times. , and .
