Figure 1From: Palatal mucosa derived fibroblasts present an adaptive behavior regarding cytokine secretion when grafted onto the gingival margin Cells characterization by fibroblast protein surface staining. Cultured cells were immunostained for fibroblast surface protein (FSP) and analyzed by a confocal microscope at an increase of 63x. (A) control; (B) stimulated by Ec LPS; (C) stimulated by Pg LPS and (D) negative control, labeled nuclei in blue (DAPI).Back to article page
