Gene transfer of somatostatin receptor type 2 by intratumoral injection inhibits established pancreatic carcinoma xenografts

Figure 1 Immunohistochemical staining of SSTR2 expression in groups I (A), II (B), and III (C) (SP, magnification ×400).

Figure 2 Western blot analysis for SSTR2 expression. Lanes 1 and 2: experimental group; lanes 3 and 4: control groups.

Figure 3 Pancreatic xenografts in the nude mice. Tumors in groups I (A) and II (B) were bigger than that in group III (C), and dark parts display distinct necrosis.
