Figure 9. Nomarski images of 3 day and 7 day vehicle and bone morphogenetic protein 7 (BMP7) injected retinal sections. Retinal sections of vehicle and BMP7 injected eyes were imaged by Nomarski microscopy on day 3 and day 7. The vehicle injected retinal sections showed no thickened Müller glial trunks at the 3 day and 7 day stage. The BMP7 injected retinas for the 3 day and 7 day stage showed very few thickened Müller glial trunks arrows), suggesting that BMP7 triggers mild gliosis in the retina. n=3 for each day and condition. Scale bar A=50 μm applies to all panels.
