    Proteintech cleaved caspase 3 immunofluorescence
    TMZ+TTF treatment enhances apoptotic responses in glioblastoma cells. (A) Immunofluorescence staining of <t>cleaved</t> <t>caspase‐3</t> (red) and nuclei (blue, DAPI) in U251 and SHG140 cells under different treatment conditions. (B) Quantification of cleaved caspase‐3 fluorescence intensity. (C, E) Representative Annexin V‐FITC/PI flow cytometry plots showing the distribution of viable and apoptotic cell populations at 24 and 48 h in U251 and SHG140 cells, respectively. Lower left: Viable cells; lower right: Early apoptotic cells; upper right: Late apoptotic cells; upper left: PI‐positive non‐apoptotic/dead cells. (D, F) Quantitative analysis of viable‐cell fractions derived from Annexin V‐FITC/PI flow cytometry in U251 and SHG140 cells at 24 and 48 h. For cleaved caspase‐3 quantification, three random 20× fields were averaged within each independent experiment. At least 10,000 events were acquired per flow‐cytometry sample. Data are presented as mean ± SD ( n = 3 independent experiments). Statistical analysis was performed using one‐way ANOVA followed by Tukey's multiple comparisons test within each time point. * p < 0.05, ** p < 0.01, *** p < 0.001, **** p < 0.0001.

    TMZ+TTF treatment enhances apoptotic responses in glioblastoma cells. (A) Immunofluorescence staining of cleaved caspase‐3 (red) and nuclei (blue, DAPI) in U251 and SHG140 cells under different treatment conditions. (B) Quantification of cleaved caspase‐3 fluorescence intensity. (C, E) Representative Annexin V‐FITC/PI flow cytometry plots showing the distribution of viable and apoptotic cell populations at 24 and 48 h in U251 and SHG140 cells, respectively. Lower left: Viable cells; lower right: Early apoptotic cells; upper right: Late apoptotic cells; upper left: PI‐positive non‐apoptotic/dead cells. (D, F) Quantitative analysis of viable‐cell fractions derived from Annexin V‐FITC/PI flow cytometry in U251 and SHG140 cells at 24 and 48 h. For cleaved caspase‐3 quantification, three random 20× fields were averaged within each independent experiment. At least 10,000 events were acquired per flow‐cytometry sample. Data are presented as mean ± SD ( n = 3 independent experiments). Statistical analysis was performed using one‐way ANOVA followed by Tukey's multiple comparisons test within each time point. * p < 0.05, ** p < 0.01, *** p < 0.001, **** p < 0.0001.
