摘要:
Methods for treating or preventing neointima stenosis are disclosed. The methods generally involve the use of a TGFβ inhibitor, a SMAD2 inhibitor, an FGF Receptor agonist, a Let-7 agonist, or a combination thereof, to inhibit endothelial-to-mesenchymal transition (Endo-MT) of vascular endothelial cells into smooth muscle cells (SMC) at sites of endothelial damage. The disclosed methods can therefore be used to prevent or inhibit neointimal stenosis or restenosis, e.g., after angioplasty, vascular graft, or stent. Also disclosed are methods for increasing the patency of biodegradable, synthetic vascular grafts using a composition that inhibits Endo-MT. A cell-free tissue engineered vascular graft (TEVG) produced by this method is also disclosed.
摘要(中):
公开了治疗或预防新内膜狭窄的方法。 所述方法通常涉及使用TGF-bgr; 抑制剂,SMAD2抑制剂,FGF受体激动剂,Let-7激动剂或其组合,以将血管内皮细胞的内皮 - 间质转化(Endo-MT)抑制在内皮细胞部位的平滑肌细胞(SMC) 损伤。 因此,所公开的方法可用于预防或抑制新生内膜狭窄或再狭窄,例如在血管成形术,血管移植物或支架之后。 还公开了使用抑制Endo-MT的组合物来增加可生物降解的合成血管移植物通畅的方法。 还公开了通过该方法产生的无细胞组织工程化血管移植物(TEVG)。
