Figure 4. Apoptotic effect of HMWp treatment on MCF7 tumors.

Figure 4

Tumor tissue sections from mice treated with (A) PBS (control) and (B) HMWp were stained with TUNEL (representative images at 100 × magnification). Dark arrows indicate the apoptotic cells (stained in dark brown). (C) Percentage of TUNEL-positive cells detected in tumor sections from PBS control and HMWp-treated mice. Data are expressed as mean ± SD (n = 6). ∗ indicates significant difference in the average percentage of TUNEL-positive cells in control and treatment groups (p < 0.05).
