Expression of proangiogenic angiomiR miR-126 is higher in CD34⁺ PBMC subpopulations. (A) Confirmation of microRNA-array results and expression of other potentially proangiogenic angiomiR as determined by RT-PCR (n = 6-8). (B) Expression levels of other potentially antiangiogenic miR in the different MNC subpopulations (n = 6-8). All angiomiR expression is normalized to U6 small nuclear RNA and expressed as normalized value (NV). U6 levels were not altered in the different MNC subpopulations (data not shown). Data are mean ± SEM.
