Bevacizumab had no significant effects on Hewga-CCS cell growth. (A) Hewga-CCS cells were cultured in serum-containing medium in the absence or presence of 10, 50, 100, and 500 μg/mL of bevacizumab. The cell numbers were counted. Bars: SD. n.s.; not significant. (B) Nude mice were inoculated subcutaneously in the flank with 1 × 10⁷ Hewga-CCS cells. When the tumors reached a palpable size, the mice were treated twice per week with intraperitoneal injection of 200 μg of bevacizumab or PBS, following which the tumor size was measured. Bars: SE. n.s.; not significant.
