We have suggested that bone marrow-derived progenitor cells may contribute to the pathogenesis of vascular diseases. On the other hand, It was reported that bone marrow cells do not participate substantially in vascular remodeling in other experimental systems. in this study, three distinct types of mechanical vascular injuries were induced in the same mouse whose bone marrow had been reconstituted with that of GFP or LacZ mice. All injuries are known to cause smooth muscle cell (SMC) hyperplasia. At 4 weeks after wire-mediated endovascular injury, a significant number of the neointlmal and medial cells derived from bone marrow. In contrast, marker-positive cells were seldom detected in the lesion induced by perivascular cuff replacement. There were only a few bone marrow-derived cells in the neointima after ligation of the common carotid artery. These results indicate that the origin of Intimal cells is diverse and that contribution of bone marrow-derived cells to neointlmal hyperpiasia depends on the type of model.

我们认为，骨髓来源的祖细胞可能有助于血管疾病的发病机制。另一方面，据报道，在其他实验系统中，骨髓细胞基本上不参与血管重塑。在这项研究中，在同一只小鼠中诱导了三种不同类型的机械性血管损伤，所述小鼠的骨髓已经用GFP或LacZ小鼠的骨髓重建。已知所有损伤都会引起平滑肌细胞（SMC）增生。在导丝介导的血管内损伤后4周，大量新生内膜和中膜细胞来源于骨髓。相反，标记物阳性细胞很少检测到血管周围袖带置换引起的病变。颈总动脉结扎后新生内膜中仅有少量骨髓源性细胞。这些结果表明，内膜细胞的来源是多样的，骨髓来源的细胞对新生内膜增生的贡献取决于模型的类型。
