Figure 6. Detection of neurotrophic factor receptors in Müller and photoreceptor cells

TrkB and CNTF-α were undetectable in photoreceptor cells; however, while TrkB was detected in only 10% of Müller cells, CNTF receptor α was observed in approximately 1/3 of the Müller cells. FGF receptor 1 was observed in approximately half of the Müller cells and 25% of the rod photoreceptors, but these differences were not statistically significant. An asterisk (*) is used to indicate p<0.05. Filled bars represent photoreceptors while unfilled bars represent Müller cells. Error bars represent standard error of the mean (SEM).
