Fig 4. CPX induced apoptosis in T-ALL cells.
(A) and (B) Flow cytometric analysis showed an increased rate of early stage of apoptosis (Annexin V-FITC+/PI-, H4) after 12 h treatment of CPX (10 μM) and both rates of the early and late phase of apoptotic cell death (Annexin V-FITC+/PI+, H2) were increased after 24 h treatment in GC resistant cells of CEM-C1 and Jurkat, as well as GC-sensitive CEM-C7 cells.
