Production of SRp20 in fibroblasts from BALF and bronchial biopsies from patients with SSc and mild asthma. Fibroblasts were harvested in lysis buffer as described in the Method section. Equal amounts of protein were loaded on 4–12% Bis-Tris gels. The level of SRp20 expression was determined by Western Blotting and further quantified by measuring the optical density of the bands. Values are presented as means ± SEM for n = 5 patients/group.
