Figure 1. Immunohistochemical staining of non-cultured oral mucosa. (A) β1 integrin, (B) PPAR
. β1 integrin staining was more intense in the basal layer and a few layers above the basal layer at the tops of the ridges than seen at the bases of the ridges. The differential PPAR
expression was more distinct in the basal layer at the tops of the ridges. D11 EVPOME: (C) β1 integrin, (D) PPAR
. D11 EVPOME showed an expression pattern similar to that seen in native oral mucosa.
