Figure 7.

Proliferation of wild type (wt) and α8 integrin-deficient (a8−/−) mesangial cells seeded on fibrillin-1 fragment (A). Cells were serum starved in medium containing 0.1% fetal calf serum (FCS). Proliferation was stimulated with addition of 2% fetal calf serum. B: Proliferation on fibronectin was evaluated as a positive control. Data are means ± sd. * P < 0.05 vs. respective serum starved control (0.1% FCS). # P < 0.05 vs. serum starved wt. Results are representative for 3 similar experiments.
