Figure 1 A, Detection of the c-kit marker by immunohistochemistry. Two mast cells (arrows) are identified in the interstitium of the myocardium in an EMB (×250). B, Detection of the c-kit marker by immunohistochemistry. Mast cell (arrow) is identified in a right atrial appendage specimen (×200). C, Mast cell (arrow) co-expresses c-kit and the hematopoietic lineage marker CD45 (combined immunofluorescence with rabbit polyclonal anti-c-kit antibody revealed with cyanin-2 green fluorescence and mouse monoclonal anti-CD45 antibody revealed with cyanin-3 red fluorescence) (×150). D, Mast cell co-expresses c-kit and the mast cell lineage marker tryptase (combined immunofluorescence with rabbit polyclonal anti-c-kit antibody revealed with cyanin-2 green fluorescence and mouse monoclonal anti-tryptase antibody revealed with cyanin-3 red fluorescence) (×2.000).

Figure 2 A, Anti-MDR-1 immunohistochemistry. In the normal kidney used as positive control tissue, the MDR-1 antibody detects a strong signal in the tubules (×350). B, Anti-islet-1 immunohistochemistry. In the neonatal pancreas used as positive control tissue, islet-1 is expressed in the nuclei of the Langerhans islets (×500). C, c-kit–positive mast cells (arrows) do not express the cardiac myocyte lineage marker Nkx2.5 (arrowheads) (combined immunofluorescence with rabbit polyclonal anti-c-kit antibody revealed with cyanin-3 red fluorescence and mouse monoclonal anti-Nkx2.5 antibody revealed with cyanin-2 green fluorescence) (×200). D, c-kit–positive mast cells (arrows) do not express the endothelial cell lineage marker CD105 (arrowheads) (combined immunofluorescence with rabbit polyclonal anti-c-kit antibody revealed with Alexa 555-red fluorescence and mouse monoclonal anti-CD105 antibody revealed with cyanin-2 green fluorescence) (×350).
