Figure 2From: Effects of zinc supplementation and zinc chelation on in vitro β-cell function in INS-1E cellsCell cycle. The proportions of INS-1E cells in the S and G2/M phases were determined after exposure to ZnCl2(A, B) or TPEN (C, D) for 24 h in the presence of 11 mM glucose. Data are shown as the mean ± SEM (n = 4–6). *P < 0.05.Back to article page
