Figure 7. Effect of TPO on Bcl-2 and BAX of C17.2 cells at different time intervals. Cells were stimulated for the selected times with 100 ng/mL of TPO. Bcl-2 and BAX were detected by Western blot. (A) Levels of Bcl-2 and BAX at different time intervals. (B) Semiquantitative evaluation of TPO for antiapoptotic effects via Bcl-2/BAX. * P < 0.05, ** P < 0.01.
