However, the precise mechanism operative in this negative regulation is not clear. In this study, we show that marrow adipocytes express neuropilin-1 (NRP1) as a function of differentiation and inhibit regeneration of hematopoiesis by three principal mechanisms: one, by inducing apoptosis in hematopoietic stem/progenitor cells (HSPCs) through the death receptor-mediated pathway; two, by downregulating CXCR4 expression on the HSPCs through ligand-mediated internalization; and three, by secreting copious amounts of transforming growth factor β1 (TGFβ1), a known inhibitor of hematopoiesis. Silencing of NRP1 in these adipocytes rescued the apoptosis of cocultured HSPCs and boosted the CXCR4 surface expression on them, showing an active role of NRP1 in these processes. However, such silencing had no effect on TGFβ1 secretion and consequent inhibition of hematopoiesis by them, showing that secretion of TGFβ1 by adipocytes is independent of NRP1 expression by them. Surprisingly, mesenchymal stromal cells modified with NRP1 supported expansion of HSPCs having enhanced functionality, suggesting that NRP1 exerts a context-dependent effect on hematopoiesis. Our data demonstrate that NRP1 is an important niche component and exerts context-dependent effects on HSPCs. Based on these data, we speculate that antibody- or peptide-mediated blocking of NRP1-HSC interactions coupled with a pharmacological inhibition of TGFβ1 signaling may help in combating the negative regulation of post-transplant regeneration of hematopoiesis in a more effective manner."xsd:string |
