用于组织工程1 -3、组织修复以及药物4和生长因子5释放的新型生物相互作用水凝胶的开发在过去十年中引起了相当大的关注。我们的注意力集中在基于细胞外基质(ECM)的水凝胶上,ECM是一种共价和非共价分子相互作用的异质集合,主要由蛋白质和糖胺聚糖(GAG)组成6。在ECM中,共价相互作用将硫酸软骨素(CS)、硫酸乙酰肝素(HS)和其他硫酸化GAG连接到核心蛋白,形成蛋白聚糖(PG)。非共价相互作用包括PG的连接模块与透明质酸(HA)的结合、与离子的静电缔合、多糖链的水合和三螺旋形成以产生胶原原纤维。
The development of novel biointeractive hydrogels for tissue engineering1–3, tissue repair, and release of drugs4 and growth factors5 has attracted considerable attention over the past decade. Our attention has focused on hydrogels based on the extracellular matrix (ECM), a heterogeneous collection of covalent and noncovalent molecular interactions comprised primary of proteins and glycosaminoglycans (GAGs)6. In the ECM, covalent interactions connect chondroitin sulfate (CS), heparan sulfate (HS) and other sulfated GAGs to core proteins forming proteoglycans (PGs). Noncovalent interactions include binding of link modules of PGs to hyaluronan (HA), electrostatic associations with ions, hydration of the polysaccharide chains, and triple helix formation to generate collagen fibrils.
