Tissue Engineering Approach

Rapid production of cartilaginous extracellular matrix (ECM) is required for scale up of any articular cartilage tissue engineering approach. Although several different methods have been investigated to increase the rate of cartilaginous ECM synthesis (e.g. growth factor stimulation, mechanical loading, etc.), there is evidence to suggest that cell cycle synchronization increases rate of ECM deposition. The issue with primary articular chondrocytes (PACs) is that routine methods to synchronize cells within a particular phase of the cell cycle rely on the use of monolayer culture, which is known to elicit cellular de-differentiation. This required development of a novel method of synchronizing cells within the S phase of the cell cycle during cell isolation. The objective of this study was to test whether synchronizing PACs would improve deposition of cartilaginous ECM in a three-dimensional culture model. Findings suggested that cell cycle synchronization was a viable method of improving the rate of matrix deposition in PACs.

Cartilage lesions fail to heal spontaneously, leading to the development of chronic conditions which worsen the life quality of patients. Three-dimensional scaffold-based bioprinting holds the potential of tissue regeneration through the creation of organized, living constructs via a “layer-by-layer” deposition of small units of biomaterials and cells. This technique displays important advantages to mimic natural cartilage over traditional methods by allowing a fine control of cell distribution, and the modulation of mechanical and chemical properties. This opens up a number of new perspectives including personalized medicine through the development of complex structures (the osteochondral compartment), different types of cartilage (hyaline, fibrous), and constructs according to a specific patient’s needs. However, the choice of the ideal combination of biomaterials and cells for cartilage bioprinting is still a challenge. Stem cells may improve material mimicry ability thanks to their unique properties: the immune-privileged status and the paracrine activity. Here, we review the recent advances in cartilage three-dimensional, scaffold-based bioprinting using stem cells and identify future developments for clinical translation. Database search terms used to write this review were: “articular cartilage”, “menisci”, “3D bioprinting”, “bioinks”, “stem cells”, and “cartilage tissue engineering”.

The Impact

Limitations associated with the use of autologous chondrocytes (CH) for cartilage tissue engineering beget the need for alternative cell sources. Mesenchymal stem cells (MSC) are clinically attractive due to their ability to undergo chondrogenesis in three-dimensional culture [1,2]; however, when compared to CH, MSC fail to develop functional equivalence [2,3]. We have previously shown a marked depth-dependence in local equilibrium modulus of MSC-laden gels, with the superficial zones (where maximal media exchange occurs) considerably stiffer than regions removed from nutrient supply (center and bottom of construct); less dramatic depth-dependence was observed in CH-laden gels [4]. Similarly, other studies have shown depth-dependent properties in CH-laden gels with the construct edge generally stiffer than the center [5]. Given this apparent influence of nutrient supply, the objective of the current study was to assess the impact of dynamic culture (via orbital shaking) on the development of depth-dependent mechanical properties in both MSC and CH-laden hydrogels. Furthermore, we assessed cell viability and matrix content throughout the construct depth to determine the mechanism by which this depth-dependency arises. We hypothesized that improved nutrient transport would reduce construct inhomogeneity (particularly for MSC-laden constructs) and improve bulk mechanical properties.

Dimensional Printing

Although there have been remarkable advances in cartilage tissue engineering, construction of irregularly shaped cartilage, including auricular, nasal, tracheal, and meniscus cartilages, remains challenging because of the difficulty in reproducing its precise structure and specific function. Among the advanced fabrication methods, three-dimensional (3D) printing technology offers great potential for achieving shape imitation and bionic performance in cartilage tissue engineering. This review discusses requirements for 3D printing of various irregularly shaped cartilage tissues, as well as selection of appropriate printing materials and seed cells. Current advances in 3D printing of irregularly shaped cartilage are also highlighted. Finally, developments in various types of cartilage tissue are described. This review is intended to provide guidance for future research in tissue engineering of irregularly shaped cartilage.
