Vasculogenic conditioning of peripheral blood mononuclear cells promotes endothelial progenitor cell expansion and phenotype transition of anti-inflammatory macrophage and T lymphocyte to cells with regenerative potential.
Bottom Line: The resulting cells (QQMNCs) in EPC colony-forming assay generated significantly more definitive EPC colonies than PBMNCs.Using murine ischemic hindlimb models, the efficacy of QQMNC intramuscular transplantation (Tx) was compared to that of PBMNCTx, cultured "early EPC" Tx (eEPCTx), and granulocyte colony-stimulating factor mobilized CD34(+) cell Tx (GmCD34Tx).Laser Doppler imaging revealed the blood perfusion recovery in ischemic hindlimbs after QQMNCTx superior to after PBMNCTx and eEPCTx, but also earlier than after GmCD34Tx.

Mentions: We investigated the potential of QQMNCs to treat ischemia, using a mouse ischemic hindlimb model; the effect was evaluated by blood flow measurement for 21 days after ischemic surgery. We compared the effect of QQMNCTx with that of no‐cell Tx (IMDM medium‐injected mice:IMDM control) or PBMNCTx (Figure 5A).
