Figure 8. Exogenous human apo-transferrin protects Müller glial cells from wild-type mice from iron-induced stress. The Müller glial (MG) cells from wild-type (WT) mice at the first passage were treated with 100 µM of FeCl₃-NTA (FN) in presence or absence of different concentrations (2.5, 5, 10, and 20 ng/ml) of human apo-transferrin (h apo-Tf). Their number was determined by counting in comparison to control condition. Each column represents the mean ±SEM. The asterisk represents statistical significance of differences from FN alone, p<0.05. Data considered not significant compared to control are marked NS.
