Effect of VEGF-Trap on neonatal mouse thymocytes. (A) Graph showing total thymocyte numbers isolated from mice given VEGF-Trap or Fc control on day 1, and analyzed 7 days later. *P < .001. (B) Effect of VEGF inhibition on T-cell subset numbers. The CD4−CD8− and CD4+CD8− cells are shown as cell number × 106 (#), whereas the CD4+CD8+ cell subset is cell number × 107 (##). *P = .04; **P = .004; ***P < .001. n = 4 pooled VEGF-Trap litters (■) and n = 5 individual Fc control mice (). Error bars represent standard deviation.
