Figure 4From: Stable SET knockdown in head and neck squamous cell carcinoma promotes cell invasion and the mesenchymal-like phenotype in vitro, as well as necrosis, cisplatin sensitivity and lymph node metastasis in xenograft tumor modelsCharacteristics of the HN12shSET xenograft tumors formed in nude mice. (A) Images of tumors formed from HN12shSET cells implanted in the flanks of Balb/c nude mice (n = 10). (B) The HN12shControl cells formed a solid tumor, whereas the HN12shSET tumors were similar to a large cyst and contained a yellow-white necrotic liquid that was visible when the tumors were cut. Representative images of tumors 4 weeks after cell injection are presented. (C) The volume of the tumors formed by HN12shSET cells. (D) The number of Ki67-positive tumor cells, determined as described in the Methods section. The data are reported as the means and standard deviations (*p < 0.05).Back to article page
