PAX-8 and VDR receptor analysis by immunocytochemistry. On the left the score of positive cells, counted in 12 different areas, and on the right the representative pictures, obtained through microscopy at original magnification of X40, are reported. A, PAX-8 staining: the ratio is reported as mean (SD) (%) of positive cells of 4 technical replicates. The scale reported in the first column on the right is to be considered valid for the same antibody. B, score of positive cells for VDR receptor is reported as mean (SD) (%) of 4 technical replicates. * P < 0.05 vs control; ** P < 0.05 vs VitD. The scale reported in the first column is to be considered valid for the same antibody
