Effects of bFGF on the Modulation of Apoptosis in Gingival Fibroblasts with Different Host Ages
Figure 2
Changes in the gene expression of fibronectin-1 and type-I collagen during differentiation in cultured GFs. Total RNA was extracted from GFs as the cells became confluent; GFs were incubated with bFGF of 0.5 or 1.0 ng/mL for 24 hrs. The mRNA expression levels of fibronectin-1 (a) and type-I collagen (b) were determined by means of a real-time PCR analysis, normalized relative to the expression of GAPDH, and depicted as the rate of change in gene expression. Error bars indicate a standard deviation. , *, **.
