CA2 and DPP4 (CD26) expression in fibroblasts. Cancer associated fibroblasts from two patients with IDC were cultured in the presence or absence (control-1st row) of 1,25(OH)2D3 0.5 nM (2nd row) or 100 nM (3rd row) and processed for immunostaining with specific antibodies and DAPI for nuclear staining (on the left). (A) CA2 cytoplasmic granular staining and (B) DPP4 cytoplasmic staining appears in green. scale bar: 25μm.
