Our in vivo data showed that the volume of tumors derived from Met shRNA CD44v6+ cells in BALB/c nude mice was smaller than that of tumors derived from cells treated with scrambled control shRNA in a subcutaneous xenograft tumor model (Figure 2(e); day 21 tumor volume, 848.6 ± 157.0 mm3 vs. 221.0 ± 23.03 mm3, ∗p < 0.05, ∗∗p < 0.01, t-test). Here, MET is linked to neoplasm.
