Abstract

Healing of dense regular connective tissue, due to a high fiber-to-cell ratio and low metabolic activity and regeneration potential, frequently requires surgical implantation or reconstruction with high risk of reinjury. An alternative to synthetic implants is using bioscaffolds obtained through decellularization, a process where the aim is to extract cells from the tissue while preserving the tissue-specific native molecular structure of the ECM. Proteins, lipids, nucleic acids and other various extracellular molecules are largely involved in differentiation, proliferation, vascularization and collagen fibers deposit, making them the crucial processes in tissue regeneration. Because of the multiple possible forms of cell extraction, there is no standardized protocol in dense regular connective tissue (DRCT). Many modifications of the structure, shape and composition of the bioscaffold have also been described to improve the therapeutic result following the implantation of decellularized connective tissue. The available data provide a valuable source of crucial information. However, the wide spectrum of decellularization makes it important to understand the key aspects of bioscaffolds relative to their potential use in tissue regeneration.

摘要

由于高密度规则结缔组织的纤维与细胞比例高、代谢活性和再生潜力低,因此常需要通过手术植入或重建,但这存在较高的再次损伤风险。合成植入物的替代方法是使用脱细胞生物支架,这是一种从组织中提取细胞而同时保留 ECM 组织特异性天然分子结构的过程。蛋白质、脂质、核酸和其他各种细胞外分子在分化、增殖、血管生成和胶原蛋白纤维沉积中起着重要作用,这些过程是组织再生的关键。由于细胞提取的多种可能形式,高密度规则结缔组织(DRCT)中没有标准化的方案。为了改善脱细胞结缔组织植入后的治疗效果,也已经描述了许多对生物支架的结构、形状和组成的改进。现有数据提供了宝贵的关键信息来源。然而,脱细胞处理的广泛范围使得理解生物支架的关键方面及其在组织再生中的潜在用途变得非常重要。
