From: Malignant transformation of oral leukoplakia is associated with macrophage polarization
Epithelial versus subepithelial macrophage infiltration in transforming OLP, non-transforming OLP, OSCC and healthy mucosa. Box-plots show the median ratio of macrophage infiltration (positive cells/mm2) between the epithelial versus the subepithelial compartment of transforming OLP, non-transforming OLP, OSCC and healthy oral mucosa: a CD68 epithelial/subepithelial, b CD163 epithelial/subepithelial, c CD11c epithelial/subepithelial. All p-values generated by Mann–Whitney-U test are indicated. OLP oral leukoplakia, OSCC oral squamous cell carcinoma
