From: L-arginine enhances cell proliferation and reduces apoptosis in human endometrial RL95-2 cells
Effect of L-arginine on human endometrial RL95-2 cell apoptosis as assessed by TUNEL assay and fluorescent microscopy. Representative micrographs of cells exposed to (A) 0 μmol/L, (B) 200 μmol/L, or (C) 800 μmol/L L-arginine. Cells staining green are TUNEL positive cells experiencing DNA fragmentation. (D) Percentage of cells staining positive for TUNEL after exposure to either 0 μmol/L, 200 μmol/L, 800 μmol/L L-arginine. Each bar represents the mean ± S.E.M.; a,b means without common letters are significantly different (P < 0.05).
