组织工程策略可用于增强韧带重建过程中软组织移植物的骨整合。韧带断裂会导致关节积血,这是一种富含成骨性人间充质干细胞(hMSC)的急性关节内出血。为了确定一种合适的生物材料,将关节积血液衍生的 hMSCs (HF-hMSCs) 结合起来用于治疗应用,这项工作研究了由两种形式的聚(d,l-乳酸-乙醇酸)(PLGA)制成的微粒的生物相容性,其中一种是用相等的乳酸与乙醇酸单体比例合成的(PLGA) 50:50)和另一种乳酸比例较高(PLGA 85:15),可提供更长的生物降解时间。两种类型的微粒的表面均通过烯丙胺的等离子体聚合进行功能化,以增加亲水性并促进细胞附着。 HF-hMSC 附着在两种形式的 PLGA 微粒的表面并沿其扩散。与在组织培养塑料上分化的对照培养物相比,用 PLGA 培养时 HF-hMSC 的成骨反应增强,并且这与所用聚合物的类型无关。我们已经证明,表面工程 PLGA 微粒是一种适合与 HF-hMSC 结合的生物材料,并且仅在考虑每种生物医学应用的生物降解时间时,PLGA 的选择才有意义。 © 2013 Wiley periodicals, Inc.

Tissue engineering strategies can be applied to enhancing osseous integration of soft tissue grafts during ligament reconstruction. Ligament rupture results in a hemarthrosis, an acute intra‐articular bleed rich in osteogenic human mesenchymal stem cells (hMSCs). With the aim of identifying an appropriate biomaterial with which to combine hemarthrosis fluid‐derived hMSCs (HF‐hMSCs) for therapeutic application, this work has investigated the biocompatibility of microparticles manufactured from two forms of poly(d,l‐lactic‐co‐glycolic acid) (PLGA), one synthesized with equal monomeric ratios of lactic acid to glycolic acid (PLGA 50:50) and the other with a higher proportion of lactic acid (PLGA 85:15) which confers a longer biodegradation time. The surfaces of both types of microparticles were functionalized by plasma polymerization with allylamine to increase hydrophilicity and promote cell attachment. HF‐hMSCs attached to and spread along the surface of both forms of PLGA microparticle. The osteogenic response of HF‐hMSCs was enhanced when cultured with PLGA compared with control cultures differentiated on tissue culture plastic and this was independent of the type of polymer used. We have demonstrated that surface engineered PLGA microparticles are an appropriate biomaterial for combining with HF‐hMSCs and the selection of PLGA is relevant only when considering the biodegradation time for each biomedical application. © 2013 Wiley Periodicals, Inc.
