Gene Expression and Accumulation of Fibrillin-1, Fibrillin-2, and Tropoelastin in Cultured Periodontal Fibroblasts

E. Tsuruga, K. Irie, and T. Yajima
The authors describe, for the first time, gene expression and the accumulation of fibrillins in cultured fibroblasts, and suggest that fibrillins-1 and -2 may have distinct functions in regulating the process of elastogenesis.
