Abstract

Hydrogels containing chondrocytes have exhibited excellent potential in regenerating hyaline cartilage. However, chondrocytes are vulnerable to dedifferentiation during in vitro culture, leading to fibrosis and mechanical degradation of newly formed cartilage. It is proposed to modulate cartilage formation via the developed chondrocyte pericellular matrix (PCM) -like scaffolds for the first time, in which the S, M, and L-sized scaffolds are fabricated by femtosecond laser maskless optical projection lithography (FL-MOPL) of bovine serum albumin-glyceryl methacrylate hydrogel. Chondrocytes on the M PCM-like scaffold can maintain round morphology and synthesize extracellular matrix (ECM) to induce regeneration of hyaline cartilage microtissues by geometrical restriction. A series of M PCM-like scaffolds is fabricated with different stiffness and those with a high Young's modulus are more effective in maintaining the chondrocyte phenotype. The proposed PCM-like scaffolds are effective in modulating cartilage formation influenced by pore size, depth, and stiffness, which will pave the way for a better understanding of the geometric cues of mechanotransduction interactions in regulating cell fate and open up new avenues for tissue engineering.

摘要

水凝胶中包含的软骨细胞在再生透明软骨方面表现出了巨大的潜力。然而,软骨细胞在体外培养过程中容易去分化,导致新形成的软骨纤维化和机械降解。本研究首次提出通过开发的软骨细胞细胞外基质(PCM)样支架来调节软骨形成,其中 S、M 和 L 三种尺寸的支架是通过牛血清白蛋白-甘油甲基丙烯酸酯水凝胶的飞秒激光无掩模光学投影光刻(FL-MOPL)制备的。M PCM 样支架上的软骨细胞能够保持圆形形态并合成细胞外基质(ECM),通过几何限制诱导透明软骨微组织的再生。用不同弹性模量的一系列 M PCM 样支架进行了制备,具有较高杨氏模量的支架更有利于维持软骨细胞表型。提出的 PCM 样支架在调节软骨形成方面是有效的,其影响因素包括孔径、深度和弹性模量,这将为更好地理解机械转导相互作用的几何线索在调节细胞命运方面的作用铺平道路,并为组织工程开辟新途径。
