Following 24 hours of culture, compensatory hypertrophy was observed and cellular apoptosis increased. Hypoxia enhanced the migration ability of retinal MOiler cells and induced the expression of a-smooth muscle actin. Oxidative stress altered the morphology of MOiler cells when compared with hypoxia treatment.展开更多
