Chondrocyte Sheet

Despite many outstanding research works on cartilage tissue engineering, actual clinical application is not quite successful because of the absorption and progressive distortion of tissue engineered cartilage. We have developed a new method of cartilage tissue engineering comprising chondrocyte mixed Pluronic F-127 and cultured chondrocyte cell sheet which entirely cover the cell-Pluronic complex. We believe the addition of cultured chondrocyte cell sheet enhances the efficacy of chondrogenesis in vivo. Human ear cartilage piece was enzymatically dissociated and chondrocyte suspension was acquired. Chondrocytes were cultured and expanded as the routine manner. Cultured chondrocytes were plated in high-density monolayer and cultured with Chondrogenic media in 5% CO2 incubator. After 3 weeks of culture, chondrocyte cell sheet was formed and complete single sheet of chondrocyte could be harvested by gentle manipulation of culture plate with a cell scraper. Chondrocyte-Pluronic complex was established by mixing 1x 106 cells with 0.5 of Pluronic F- 127. Chondrocyte-Pluronic complex was completely covered with a sheet of cultured chondrocyte. The completed tissue engineered constructs were implanted into the subcutaneous tissue pocket of nude mice on the back. Tissue engineered constructs without cultured cell sheet were used as control. Samples were harvested at 8 weeks postoperatively and they were subjected to histological analysis and assayed for glycosaminoglycan (GAG), and type II collagen. Grossly, the size of cartilage specimen of cultured chondrocyte cell sheet covered group was larger than that of the control. On histologic examination, the specimen of cultured chondrocyte cell sheet covered group showed lacunae-containing cells embedded in a basophilic matrix. The chondrocyte cell sheet covered group specimen resembled mature or immature cartilage. The result of measurement of GAG and type II collagen of cartilage specimen of cultured chondrocyte sheet covered group was higher than that of the control. In conclusion, the new method of cartilage tissue engineering using chondrocyte cell sheet seems to be an effective method providing higher cartilage tissue gain and reliable success rate for cartilage tissue engineering.

Human cartilage has relatively slow metabolism compared to other normal tissues. Cartilage damage is of great clinical consequence since cartilage has limited intrinsic healing potential. Cartilage tissue engineering is a rapidly emerging field that holds great promise for tissue function repair and artificial/engineered tissue substitutes. However, current clinical therapies for cartilage repair are less than satisfactory and rarely recover full function or return the diseased tissue to its native healthy state. Kartogenin (KGN), a small molecule, can promote chondrocyte differentiation both in vitro and in vivo. The purpose of this research is to optimize the chondrogenic process in mesenchymal stem cell (MSC)-based chondrogenic constructs with KGN for potential use in cartilage tissue engineering. In this study, we demonstrate that KGN treatment can promote MSC condensation and cell cluster formation within a tri-copolymer scaffold. Expression of Acan, Sox9, and Col2a1 was significantly up-regulated in three-dimensional (3D) culture conditions. The lacuna-like structure showed active deposition of type II collagen and aggrecan deposition. We expect these results will open new avenues for the use of small molecules in chondrogenic differentiation protocols in combination with scaffolds, which may yield better strategies for cartilage tissue engineering.

The scaffold-free tissue engineering using spheroids is pointed out as an approach for optimizing the delivery system of cartilage construct. In this study, we aimed to evaluate the micromolded nonadhesive hydrogel (MicroTissues®) for spheroid compaction (2-day culture) and spontaneous chondrogenesis (21-day culture) using cartilage progenitors cells (CPCs) from human nasal septum without chondrogenic stimulus. CPC spheroids showed diameter stability (486 μm ± 65), high percentage of viable cells (88.1 ± 2.1), and low percentage of apoptotic cells (2.3%). After spheroid compaction, the synthesis of TGF-β1, TGF-β2, and TGF-β3 was significantly higher compared to monolayer (p<0.005). Biomechanical assay revealed that the maximum forces applied to spheroids after chondrogenesis were 2.6 times higher than for those cultured for 2 days. After spontaneous chondrogenesis, CPC spheroids were entirely positive for N-cadherin, collagen type II and type VI, and aggrecan and chondroitin sulfate. Comparing to monolayer, the expression of SOX5 and SOX6 genes analyzed by qPCR was significantly upregulated (p<0.01). Finally, we observed the capacity of CPC spheroids starting to fuse. To the best of our knowledge, this is the first time in the scientific literature that human CPC spheroids were formed by micromolded nonadhesive hydrogel, achieving a successful scaffold-free cartilage engineering without chondrogenic stimulus (low cost).
