Immunohistochemical analysis of ANXA1 expression in lymph nodes from head and neck carcinomas. a Non-metastatic lymph node (N0) samples: constitutive expression of ANXA1 in the subcapsular sinus. b Metastatic lymph node (N+) samples: endogenous ANXA1 expression increased in the lymph node tissue and in the metastatic cells (arrows). c Negative control of reaction. Sections: 2 μm. Counterstain: Hematoxylin. d Densitometry of ANXA1. Values expressed as mean ± S.E.M. *** p < 0,001
