Abstract

Osteochondral regeneration remains a key challenge because of the limited self-healing ability of the bone and its complex structure and composition. Biomaterials based on endochondral ossification (ECO) are considered an attractive candidate to promote bone repair because they can effectively address the difficulties in establishing vascularization and poor bone regeneration via intramembranous ossification (IMO). However, its clinical application is limited by the complex cellular behavior of ECO and the long time required for induction of the cell cycle. Herein, functionalized microscaffold-hydrogel composites are developed to accelerate the developmental bone growth process via recapitulating ECO. The design comprises arginine-glycine-aspartic acid (RGD)-peptide-modified microscaffolds loaded with kartogenin (KGN) and wrapped with a layer of RGD- and QK-peptide-comodified alginate hydrogel. These microscaffolds enhance the proliferation and aggregation behavior of the human bone marrow mesenchymal stem cells (hBMSCs); the controlled release of kartogenin induces the differentiation of hBMSCs into chondrocytes; and the hydrogel grafted with RGD and QK peptide facilitates chondrocyte hypertrophy, which creates a vascularized niche for osteogenesis and finally accelerates osteochondral repair in vivo. The findings provide an efficient bioengineering approach by sequentially modulating cellular ECO behavior for osteochondral defect repair.

摘要

软骨骨再生仍然是一个关键的挑战,因为骨的自我修复能力有限,且其结构和组成复杂。基于软骨内骨化 (ECO) 的生物材料被认为是一种有吸引力的候选物,可以促进骨修复,因为它们可以有效地解决通过膜内成骨 (IMO) 建立血管化和改善骨再生的困难。然而,其临床应用受到 ECO 复杂的细胞行为和诱导细胞周期所需的长时问的限制。在此,通过模拟 ECO 开发了功能化微支架-水凝胶复合材料,以加速发育性骨生长过程。该设计包括载有卡托金 (KGN) 的精氨酸-甘氨酸-天冬氨酸 (RGD)-肽修饰微支架和一层 RGD 和 QK-肽修饰的藻酸盐水凝胶。这些微支架增强了人骨髓间充质干细胞 (hBMSCs) 的增殖和聚集行为;卡托金的控释诱导 hBMSCs 分化为软骨细胞;RGD 和 QK 肽接枝的水凝胶促进软骨细胞肥大,为成骨创造了一个血管化小生境,最终在体内加速了软骨骨修复。这些发现提供了一种有效的生物工程方法,通过顺序调节细胞 ECO 行为来修复软骨骨缺损。
