In this review, materials based on polymers and hybrids possessing both organic and inorganic contents for repairing or facilitating cell growth in tissue engineering are discussed. Pure polymer based biomaterials are predominantly used to target soft tissues. Stipulated by possibilities of tuning the composition and concentration of their inorganic content, hybrid materials allow to mimic properties of various types of harder tissues. That leads to the concept of "one-matches-all" referring to materials possessing the same polymeric base, but different inorganic content to enable tissue growth and repair, proliferation of cells, and the formation of the ECM (extra cellular matrix). Furthermore, adding drug delivery carriers to coatings and scaffolds designed with such materials brings additional functionality by encapsulating active molecules, antibacterial agents, and growth factors. We discuss here materials and methods of their assembly from a general perspective together with their applications in various tissue engineering sub-areas: interstitial, connective, vascular, nervous, visceral and musculoskeletal tissues. The overall aims of this review are two-fold: (a) to describe the needs and opportunities in the field of bio-medicine, which should be useful for material scientists, and (b) to present capabilities and resources available in the area of materials, which should be of interest for biologists and medical doctors.
在本综述中,我们讨论了基于聚合物以及兼具有机和无机成分的杂化材料,这些材料用于组织工程中的修复或促进细胞生长。纯聚合物基生物材料主要用于针对软组织。由于可以调节其无机成分的组成和浓度,杂化材料能够模拟各种较硬组织的特性。这就引出了“一材多用”的概念,即指具有相同聚合物基体,但无机成分不同,以实现组织生长和修复、细胞增殖以及细胞外基质(ECM)形成的材料。此外,将药物递送载体添加到用此类材料设计的涂层和支架中,通过封装活性分子、抗菌剂和生长因子带来了额外的功能。我们从总体角度讨论这些材料及其组装方法,以及它们在各种组织工程子领域中的应用:间质组织、结缔组织、血管组织、神经组织、内脏组织和肌肉骨骼组织。本综述的总体目标有两个:(a)描述生物医学领域的需求和机遇,这对材料科学家应该是有用的;(b)介绍材料领域的能力和资源,这应该会引起生物学家和医生的兴趣。
