Furthermore, we demonstrated that patients with JIA that were treated with GC demonstrated lower levels of CD34 + CD309+ cells as compared to patients not treated with GC (0.015% [0.004%-0.06%] vs. 0.08% [0.037%-0.18%]; p = 0.023, respectively; Figure 2a). The gene discussed is KDR; the disease is juvenile idiopathic arthritis.
