Erratum: Rapid mobilization of hematopoietic progenitors by AMD3100 and catecholamines is mediated by CXCR4-dependent SDF-1 release from bone marrow stromal cells

Correction to: Leukemia advance online publication, 15 April 2011; doi: 10.1038/leu.2011.62

Since the publication of this paper, the authors have noticed an error in Figure 5, concerning the BM SDF-1 levels in the control AMD-only treated mice. The correct version is shown below.

Figure 5

Neurotransmitter stimulation induces functional SDF-1 release and rapid progenitor mobilization. (a, b) SDF-1 levels in the plasma and BM sup. (a) and circulating WBC and progenitor cells (b) in mice treated with NE or the β2 adrenergic antagonist ICI, 1 h after administration. Control mice received injections of PBS, n=6 mice/group. Values of plasma SDF-1 levels: 1.1±0.17, 1.8±0.5, 0.6±0.06, 2±0.3, 2.8±0.5 and 1.2±0.1 ng/ml, respectively, ^*P<0.05 compared with control mice, ^#P<0.05 compared with AMD3100-treated mice. (c) RT-PCR analysis (top) for mRNA expression and flow-cytometry analysis (bottom) for cell surface expression of β2 adrenergic receptor on cultured primary human BMEC. –RT=cDNA was prepared without reverse transcriptase as a control. (d) SDF-1 release from primary human BMEC in response to stimulation with ICI (10 ng/ml), n=3. (e) AMD3100-induced mobilization of progenitors in control and sympathectomized (6OHDA) of either neonate or adult mice. ^*P<0.005. n=10–15 mice/group.
