Protein expression of Wnt5a and secreted frizzled-related protein 5 (sFRP5) in healthy and diseased human gingival tissue. Periodontal biopsy specimens from healthy controls (left) and periodontitis patients (right) were processed for immunofluorescence and hematoxylin and eosin (H&E) staining. Shown are overlays of differential interference contrast and fluorescent images stained for Wnt5a (red) and sFRP5 (green), as well as merged images. Scale bar, 50 µm.
