Tumor formation in vivo. (A) Different SW480 and HT29 cell lines were injected subcutaneously into nude mice. Tumors were dissected 30 days after the inoculation and were photographed; representative tumors are shown. (B) Tumor weights were compared on day 30 after the tumor inoculation. (C) Tumor volume. Tumor volume was monitored every 3 days from day 18 after the inoculation by measuring tumor length (L) and width (W) with a sliding caliper. Tumor volume = L × W² × 0.51. Bars, mean ± SD. *P < 0.05, n > 3.
