Figure 1. Degenerate capillaries and pericyte ghosts in the β1-adrenergic receptor retina A: This panel is a bar graph of the number of degenerate capillaries in the β1-adrenergic receptor knockout (KO) mice versus
wild-type (WT) littermates. B: This panel is a bar graph of the number of pericyte ghosts in the same samples of retina from β1-adrenergic receptor KO
and their WT littermates. *p<0.05 versus WT. n=5 for each group.
