Effect of CPA on CSC markers. (A) Flow cytometric detection of CD44⁺ CD24^- lin^- cells in control and treated xenografts. (B) Flow cytometric detection of ALDH activity in control and treated xenografts. BAAA is the fluorescent product indicating ALDH activity. (C) Compiled data of CD44⁺ CD24^- flow cytometry. (D) Compiled data of ALDEFLUOR flow cytometry. *P < .05 compared with control, t test, n = 6–12. (E) Control and treated tumor sections were stained for ALDH1. Green indicates ALDH1 staining; blue, nuclear DAPI staining.
