聚合物多层胶囊(PMCs)在组织工程和再生医学的一个发展中的分支--生物胶囊方面具有很大的应用价值。在这里,我们描述了通过层层组装聚(L-赖氨酸)、海藻酸盐和壳聚糖,由外部多层膜组成的分层PMCs的制备。基质细胞的核心是液化的,包裹着人脂肪干细胞和表面功能化的胶原II-转化生长因子-β3聚(L-乳酸)微粒,用于软骨组织工程。
Polymeric multilayered capsules (PMCs) have found great applicability in bioencapsulation, an evolving branch of tissue engineering and regenerative medicine. Here, we describe the production of hierarchical PMCs composed by an external multilayered membrane by layer-by-layer assembly of poly(L-lysine), alginate, and chitosan. The core of the PMCs is liquified and encapsulates human adipose stem cells and surface-functionalized collagen II-TGF-beta 3 poly(L-lactic acid) microparticles for cartilage tissue engineering.
