Fig. 2From: Effects of concentration of amyloid β (Aβ) on viability of cultured retinal pigment epithelial cellsEffect of Aβ 1–40 on the DNA synthesis of ARPE-19 cells incubated for 24 h with Aβ 1–40. With 25 μM Aβ, there was a significant decrease in the DNA synthesis in the ARPE-19 cells. Data are the means ± SEMs for each group (n = 4)Back to article page
