mSSTR2 status of murine pheochromocytoma cells and tumors. (A) Western blot analyses of murine organs, tumors and cell cultures; (B) immunocytochemistry in MPC-mCherry cell cultures in vitro; bars: 30 µm; (C) immunohistochemistry on tissue sections of MPC-mCherry tumors; (left) overview of a tumor 4 weeks after cell injection, arrows indicate the absence of mSSTR2 in necrotic regions; bars: 1 mm; (right) membranous distribution of mSSTR2 in tumors; bars: 10 µm; (M) molecular weight of proteins in kDa; (nc) negative control in presence of blocking peptide (human SSTR2 fragment).
