Aβ peptides (WT, E22Q, E22G) affect HBMEC proliferation. (A) Cells were exposed to Aβs (1–25 µM) for 48 h and growth was evaluated by BrdU incorporation. Data are reported as cell number counted/well. Numbers represent mean ± SEM. *P < 0.05 and *P < 0.01 versus controls by Student's t-test. (B) Aβ effects on proliferation induced by FGF-2 (20 ng/ml). X: denotes initial cell counts.
