Dysregulated mRNA expression of cytokines and surface receptors in aged mice. (A–C) The mRNA levels of pro-inflammatory cytokines (A), anti-inflammatory cytokines (B), and surface receptors (C) in the BM of age-matched mice were measured by qPCR. All mRNA levels were normalized to cyclophilin A, mean ± SE (n = 4, *P < 0.05).
