PTX3 overexpression reduces Tryptase-positive mast cells infiltrate. Tryptase immunohistochemistry and morphometric analysis in mock (A) and PTX3 (B) transfected MC17-51 tumor grafts growing s.c. in syngeneic C57BL/6 mice and in wild type MC17-51 tumor grafts growing s.c. in WT C57BL/6 (D) and transgenic TgN(Tie2-hPTX3) mice (E) mice. Morphometric analysis shows a significant decrease of Tryptase-positive mast cells (arrows) following PTX3 overexpression by tumor cells (C) or by transgenic tumor stroma (F) when compared to their corresponding controls (A,D, respectively). * p < 0.05. Scale bar: (A,B,D,E) 60 µm.
