- 요약Cartilage's limited self-repair capabilities pose significant clinical challenges, particularly in complex anatomical structures like the ear. Traditional approaches such as autologous grafts and prosthetics have limitations, driving the need for novel solutions. Hydrogels have emerged as promising scaffolds due to their biocompatibility and ability to mimic the native cartilage environment. However, additional support for structural integrity is required.3D printing offers precise control over scaffold geometry and material integration, allowing for tailored constructs. Composite scaffolds combining 3D printed structures with hydrogels show promise in promoting cartilaginous ECM production. However, challenges like biological stability and cell viability need addressing. Composite scaffolds incorporating glycosaminoglycan-based hydrogels mimic native ECM composition, supporting cell survival and chondrogenic maintenance. Heparin-based hydrogels, in particular, offer enhanced chondrogenesis and growth factor sequestration, crucial for cartilage regeneration.This thesis work aimed to streamline cartilage tissue engineering by developing a novel approach for in situ assembly of bioactive composite structures in the operating room (OR), circumventing regulatory challenges associated with extensive in vitro chondrocyte culturing. Composite scaffolds capable of both biological stimulation and structural support essential for cartilage regeneration were developed in this thesis. First novel 3D printed-hydrogel composite scaffolds were developed and characterized. Next, to investigate the impact of cartilage digestion level on extracellular matrix production, isolated chondrocytes, partially digested cartilage, and minced cartilage pieces were xx encapsulated in PEGDA-DTT hydrogels. Lastly, efficacy of heparin sulfation in promoting chondrocyte maintenance and cartilaginous matrix production was assessed. Together these studies support the utilization of composite scaffolds and heparin-based hydrogels for cartilage tissue engineering.
