The angiogenic factor CCN1 promotes adhesion and migration of circulating CD34+ progenitor cells: potential role in angiogenesis and endothelial regeneration

Abstract

Tissue regeneration involves the formation of new blood vessels regulated by angiogenic factors. We reported recently that the expression of the angiogenic factor CCN1 is up-regulated under various pathophysiologic conditions within the cardiovascular system. Because CD34+ progenitor cells participate in cardiovascular tissue regeneration, we investigated whether CCN1—detected for the first time in human plasma—promotes the recruitment of CD34+ progenitor cells to endothelial cells, thereby enhancing endothelial proliferation and neovascularization. In this study, we demonstrated that CCN1 and supernatants from CCN1-stimulated human CD34+ progenitor cells promoted proliferation of endothelial cells and angiogenesis in vitro and in vivo. In addition, CCN1 induced migration and transendothelial migration of CD34+ cells and the release of multiple growth factors, chemokines, and matrix metalloproteinase-9 (MMP-9) from these cells. Moreover, the CCN1-specific integrins αMβ2 and αVβ3 are expressed on CD34+ cells and CCN1 stimulated integrin-dependent signaling. Furthermore, integrin antagonists (RGD-peptides) suppressed both binding of CCN1 to CD34+ cells and CCN1-induced adhesion of CD34+ cells to endothelial cells. These data suggest that CCN1 promotes integrin-dependent recruitment of CD34+ progenitor cells to endothelial cells, which may contribute to paracrine effects on angiogenesis and tissue regeneration.

  • Overexpression of CCN1 from an adenoviral vector accelerates re-endothelialization after balloon injury.

    “Overexpression of CCN1 from an adenoviral vector accelerates re-endothelialization after balloon injury, possibly because CCN1 can recruit CD34+ endothelial progenitor cells to the endothelial monolayer and promote their differentiation [88,138].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
