Expression of mast cells (MCs) tryptase staining on tumors. (A) Significant increase in MCs tryptase count in the tumors of arthritic SKG mice challenged with 4T1 cells versus nonarthritic Balb/C mice injected with 4T1 cells (**P < 0.01) and in arthritic PyV MT mice induced with CII versus nonarthritic PyV MT mice (**P < 0.01). Representative images of tryptase staining in (B, C): tumors taken at 400× magnification (six mice per experimental group and 10 fields per section). Brown staining represents MCs tryptase expression.
