Voir la source de CXCL12 expression ranges (median score) in the endothelial compartment of tumors in accordance to the age of client at analysis, (G) and in the stroma of UnNBs, GGNBs and GGNs

As proven in Figure 2C (still left panel), CXCR7 expression was induced in IGR-NB8 cells after three days of RA remedy (p,.01), whereas its expression was weakly detectable upon BrdU publicity. Related RA-induced CXCR7 expression sample was also detected in the SH-SY5Y and the SK-N-Be(2c) cell lines (Figure S2A, S2B). These data thus proposed that induction of CXCR7 expression, albeit weak, preferentially happened when NB cells underwent neuronal relatively than glial/schwannian differentiation. Addition of CXCL12 collectively with RA or BrdU treatment did not even more increase receptor expression in treated NB cells (Figure S2B). However, induced CXCR7 protein amounts might be also reduced, or publish-translationally modified, as they could be neither detected at the cell surface area (FACS analyses), nor in the intracellular area of treated NB cells (Immunofluorescence assays), by each anti-CXCR7 antibodies employed in this study (data not revealed). Ectopic expression of CXCR7 in NB mobile lines. Though CXCR7 was located in a minority of NB cell strains as compared to CXCR4, its expression was even so detected in some CXCR4expressing NB cells.  To that extent, specific CXCR7, CXCR4 or mixed receptors had been overexpressed in the CXCR4/CXCR7negative IGR-NB8 cell line (respectively NB867, NB8x4 and NB86467 cell traces). CXCR7 was also ectopically overexpressed in the SH-SY5Y cell line (SHSY67 cells), which expresses substantial endogenous CXCR4 levels (Determine Second). Of observe, a lessen of CXCR7 surface expression was observed in SHSY67 cells (suggest fluorescent depth of forty four) as compared to NB86467 cells (mean fluorescent depth of sixty), whilst equivalent CXCR4 surface expression was detected in these two mobile strains. Various CXCR7 expression ranges in these two double receptor-expressing mobile traces have been confirmed by semi-quantitative RT-PCR analyses (Figure 2E). Therefore, the two CXCR7/CXCR4-expressing transduced mobile lines harbored variable relative expression levels of the two CXCL12 receptors. Manage regroups regular adrenal gland and sympathetic ganglion tissues Median rating indicates regular tumor score, as established by semi-quantitative examination of the immunostaining p-worth (Student's t-check) refers to principal tumor: ns indicates not substantial, p,.05 is deemed important, p#.01 is regarded as really substantial. 
Expression of the two CXCL12 receptors in NB cell traces. (A) Qualitative RT-PCR analyses for CXCR7 and CXCR4 mRNA expression in a panel of N-, I-and S-variety NB mobile traces. GAPDH was used as gene of reference.
