Immunocytochemical Localization and Serologic Detection of Transforming Growth Factor β1

Abstract

The pattern of TGF beta 1 staining in dermal sections from patients with dcSSc, lcSSc, and morphea suggests that this cytokine is important in the pathogenesis of scleroderma. Furthermore, the presence of TGF beta 1 prior to the onset of fibrosis indicates an early involvement of this growth factor, possibly in the inflammatory stage of the disease.
