VEGF mRNA expression in peripheral white blood cells. VEGF-c mRNA expression in the peripheral white blood cells was determined using quantitative RT-PCR over time. Pair-wise multiple comparisons between groups were determined using Bonferroni’s test with α = 0.001 adjustment. Results represent the means ± SD at each time point (n = 6 per time point). Indicates a statistically significant difference between the indicated group and the *normal control group, † saline group, ‡ VX2 cell group at 15 days.
