Expression of platelet-derived growth factor receptor in periapical granuloma / 实用口腔医学杂志

Objective: To investigate the expression of platelet-derived growth factor receptor (PDGF-R) in periapical granuloma.Methods:Immunohistochemical staining was conducted on prepared specimens of 15 cases of human periapical granuloma. Results:The expression of PDGF receptor ? was detected in fibroblasts,capillary endothelial cells,plasmacytes and macrophage cells in all the 15 cases of human periapical granuloma.Conclusion:These results suggested that these cells are the target cells of PDGF, and PDGF may play an important role in the lesion.
