Effects of bFGF, silica, and silica + bFGF on fibronectin (FN) synthesized by 16HBE cells. Aliquots of cell extracts and media were subjected to gelatin-sepharose affinity chromatography and the isolated fibronectin was electrophoresed on 6% SDS-polyacrilamide gels and then fluorographed. (A) Film autoradiogram of the gels. (B) The fluorographs shown in (A) were analyzed by computerized scanning densitometry. The values are obtained assuming as 1 the untreated level for control cells. Similar results were seen in three separate experiments.
