Figure 3. Other immunohistochemical markers. Biopsy samples of native mucosa from children without (column A) and with cleft palate (CLP, columns B) were prepared for histology. Samples from cultured substitutes with cells from children without and with cleft palate are also shown. The samples were stained with antibodies against the proliferation marker Ki67 (row 1), heparan sulphate (HS, row 2), and decorin (Dec, row 3). The bar represents 75 µm, except for decorin staining, where it represents 300 µm.
