Figure 6. Apoptosis marker active caspase 3 is increased by rLOX-PP treatment.

Figure 6

(A) Immunostaining of tumors with active caspase 3 antibody, or non-immune IgG control. (A) i.t. rLOX-PP- or PBS injected tumors, and (B) tumors treated with surgically implanted empty alginate beads or rLOX-PP/alginate beads. Black arrows mark some positive-stained cells; the white arrows point to an inset containing an enlarged image of a stained cell. Scale bar = 0.005 mm for 400× and 0.002 mm for 1000×; (C) the corresponding quantifications (***, p<0.001; n = 3).
