Abstract

Mesenchymal stem cells (MSCs) accelerate regeneration of ischemic or injured tissues by stimulation of angiogenesis through a paracrine mechanism. Tumor necrosis factor-α (TNF-α)-activated MSCs secrete pro-angiogenic cytokines, including IL-6 and IL-8. In the present study, using an ischemic hindlimb animal model, we explored the role of IL-6 and IL-8 in the paracrine stimulation of angiogenesis and tissue regeneration by TNF-α-activated MSCs. Intramuscular injection of conditioned medium derived from TNF-α-treated MSCs (TNF-α CM) into the ischemic hindlimb resulted in attenuated severe limb loss and stimulated blood perfusion and angiogenesis in the ischemic limb. Immunodepletion of IL-6 and IL-8 resulted in attenuated TNF-α CM-stimulated tissue repair, blood perfusion, and angiogenesis. In addition, TNF-α CM induced migration of human cord blood-derived endothelial progenitor cells (EPCs) through IL-6- and IL-8-dependent mechanisms in vitro. Intramuscular injection of TNF-α CM into the ischemic limb led to augmented homing of tail vein-injected EPCs into the ischemic limb in vivo and immunodepletion of IL-6 or IL-8 from TNF-α CM attenuated TNF-α CM-stimulated homing of EPCs. In addition, intramuscular injection of recombinant IL-6 and IL-8 proteins resulted in increased homing of intravenously transplanted EPCs into the ischemic limb and improved blood perfusion in vivo. These results suggest that TNF-α CM stimulates angiogenesis and tissue repair through an increase in homing of EPCs through paracrine mechanisms involving IL-6 and IL-8.

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.
