Figure 2. Brd U incorporation into amelogenin-treated dental papilla cells. (A) Proliferation as measured by BrdU incorporation and quantitated as relative light units per second (r/u/s), was not altered in the presence of rH58. (B) rH72 significantly enhanced dental papilla cell proliferation at concentrations between 100 and 500 ng/mL. Results represent the means ± SE. Asterisks show significant differences. *P < 0.05 vs. control. N (for each cell of data) = 3.
