The angiogenic mechanism and therapeutic potential of PDGF-CC, a recently discovered member of the VEGF/PDGF superfamily, remain incompletely characterized. Here we report that PDGF-CC mobilized endothelial progenitor cells in ischemic conditions; induced differentiation of bone marrow cells into ECs; and stimulated migration of ECs. Furthermore, PDGF-CC induced the differentiation of bone marrow cells into smooth muscle cells and stimulated their growth during vessel sprouting. Moreover, delivery of PDGF-CC enhanced postischemic revascularization of the heart and limb. Modulating the activity of PDGF-CC may provide novel opportunities for treating ischemic diseases.
血小板衍生生长因子CC（PDGF-CC）是血管内皮生长因子（VEGF）/血小板衍生生长因子（PDGF）超家族中最近发现的成员，其血管生成机制和治疗潜力尚未完全明确。在此我们报告，PDGF-CC在缺血条件下可动员内皮祖细胞；诱导骨髓细胞分化为内皮细胞；并刺激内皮细胞迁移。此外，PDGF-CC在血管新生过程中诱导骨髓细胞分化为平滑肌细胞并刺激其生长。而且，给予PDGF-CC可增强心脏和肢体缺血后的血管再生。调节PDGF-CC的活性可能为治疗缺血性疾病提供新的机会。
