Serum from young mice improves arterial function in old arteries. Aortic elastic modulus (A), endothelium-dependent dilation (EDD) in response to increasing doses of acetylcholine (ACh) (B and C), and endothelium-independent dilation in response to increasing doses of sodium nitroprusside (SNP; D) in old arteries following exposure to serum from old vs. young mice; n = 7 or 8/group. Data represent means ± SE. *P < 0.05 old vs. young mice serum exposure. Figure created with Photoshop.
