一般描述
聚己内酯(PCL)是一种半晶态疏水性可生物降解聚酯，具有成本低、韧性好、生物相容性好等优点，在医药领域有着广泛的应用。PCL具有一些独特的性质，如:
- 在生理条件下，它的降解速度比其他生物可降解聚酯慢，这一特性可以在一段时间内用于靶组织药物的可控释放。
- 由于其疏水性，其表面润湿性较差，与生物液体的相互作用较差，导致较差的细胞黏附和增殖能力，因此与其他合成/天然聚合物混合使用。
应用
- 负载抗生素的PCL可用于治疗呼吸道感染，如肺结核。
- 已有研究关于人骨髓间充质细胞(hBMSCs)对不同比例的壳聚糖/聚己内酯(PCL)共混物的表型反应。
- PCL/生物医用陶瓷材料已被研究用于可能的骨组织再生。
- PCL/分级胰岛素/beta-5甘油磷酸酯浓度通过脂肪来源的基质细胞分化对骨软骨组织形成的作用。
- 其它通用用途包括:压出助剂、模具润滑剂、脱模剂、颜料和填料分散助剂以及聚氨酯和嵌段聚酯中的聚酯段。

The objective of this study was to develop small-diameter vascular grafts capable of eluting SDF (stromal cell-derived factor)-1α-derived peptide and SP (substance P) for in situ vascular regeneration. Polycaprolactone (PCL)/collagen grafts containing SP or SDF-1α-derived peptide were fabricated by electrospinning.
