PAX9 and SHH gene visualization in cleft-affected palatine tissue of patients using chromogenic in situ hybridization method and immersion oil. a A tissue sample of a 10-month-old child with numerous to abundant (+ +  + / +  +  + +) gene-signal-containing cells in the epithelium, a few to moderate (+ / + +) gene signals in the connective tissue, and no (0) signals in the endothelium. PAX9 CISH, × 400. b A tissue sample of a 15-month-old child with a moderate number (+ +) of gene signals in the epithelium, occasional (0/ +) gene signals in the connective tissue, and no (0) gene signals in the endothelium. SHH CISH, × 400
