Figure 4. Similar numbers of retinal arteries are present in the presence or absence of bim.
Retinas from P21 bim +/+ and bim -/- mice were wholemount stained with anti-α-smooth muscle actin to identify major arteries. Please note that the number of arteries that branch off near the optic nerve were similar in bim +/+ and bim -/- mice. Experiments were repeated with eyes from 5 mice with similar results.
