As showed in Fig. 2A,C,E, there was a profound loss of astrocytes in the retinal vaso-obliteration areas from the WT-OIR mice at P14, as indicated by the absence of star-shaped GFAP astrocyte labeling and an increase in Müller cell endfeet GFAP reactivity, which is a hallmark of retinal disease. Here, GFAP is linked to Abnormal retinal morphology.
