Elevated p-Erk in CD133+ cells. (A) Western blot analysis demonstrates elevated p-Erk in CD133+ cells compared with CD133− cells in each of the CSC clone lines 1–3. pan-Erk was used as a loading control. (B) Densitometry analysis of all three CSC lines revealed a significant increase in p-Erk levels in CD133+ cells (2 × 104 cells/cm2 plated, n = 3 lines + standard error). *P < 0.05. (C) Western blot analysis demonstrated that TGF-β stimulation results in a decrease in p-Erk levels, with a smaller decrease in CD133+ cells.
