Lacking integrin b1, CD90 and PDGFRb, CMC cells showed distinct immunophenotype and origin in comparison with circulating multipotent progenitor cells [12, 38] and perivascular multipotent progenitor cells [22, 39]. Primed by the interaction with fibrin matrix and P-selectins on activated platelets [40, 41], the immunophenotypic heterogeneity of CPLCMCs has been suggested to reflect a dynamic equilibrium amongst the acquired responsivity to extracellular Alpha 2 Antiplasmin Proteins Recombinant Proteins signals and the retained self-renewal potential [42]. Determined by the expression profile of adhesion molecules (CAMs) and glycolipids/proteoglycans, the physiological and regulatory processes underlying the trafficking of CLP-CMCs in peripheral blood were defined as comparable to these of leucocytes. Likely haematopoietic stem and progenitor cells, CLP-CMCs displayed the specialized glycoform of CD44 generally known as HCELL, suggesting to have a attainable haematopoietic origin, bone marrow derivation and transendothelial migration possible. As reported by Sackstein [15], the cell migration from vascular to extravascular compartments develops by two different mechanisms: the canonical multistep process along with the so-called step 2-bypass pathway. In the canonical pathway, following the initial tethering/rolling contact of blood-borne cellswith endothelium, CXCR4 binds to its cognate ligand CXCL1/SDF-1, thereby triggering G protein-coupled VLA-4 activation, with subsequent firm adhesion and transmigration. Within the `step 2-bypass pathway’, the activation of VLA-4 occurs by means of G protein-mediated mechanosignaling just after HCELL binding to E-selectin and/or CD44 interaction with endothelial HA. As recommended by the intracellular expression of CXCR4, the extravasation of CPL-CMCs is probably to progress by the canonical pathway. The stemness signature of CPL-CMCs was further confirmed by both the gene expression on the crucial components of self-renewal machinery (NANOG, SOX2, KLF4, STAT3) [435] as well as the practically homogenous expression of CD49f [46], that may be identified for transducing survival signals, mediating endothelial progenitor cell migration/adhesion and enhancing multipotency by way of OCT4, SOX2 and NANOG [12, 43]. Collectively, our information pointed out that the self-renewal of CPL-CMCs might be regulated most likely in embryonic stem cells wherein KLF4 connects STAT3 activation with NANOG expression right after interac.
