In situ hybridization (ISH) results for selected genes. Expression of control genes. 1, Vascular SMC; 2, intestinal SMC; 3, esophageal SMC; 4, cardiac muscle; 5, lung parenchyma; 6, diaphragm (skeletal muscle); 7, liver. A summary of ISH results is given in Table 2. They are also graphically depicted in Fig. 8. Intestinal lumen artefact staining is due to endogenous alkaline phosphatase activity (asterisk).
