OBJECTIVE
We evaluated the expression of stem/progenitor biomarkers in osteoarthritic tissue derived chondrocytes cultured using a three-dimensional (3D) thermo-reversible gelation polymer (TGP).
METHODS
The chondrocytes from discarded biopsy tissues obtained from human elderly patients with osteoarthritis were cultured using the 3D-TGP up to six weeks.
RESULTS
The chondrocytes grew in a tissue-like manner, without de-differentiation into fibroblasts, and the cells thus tissue-engineered were proven positive for CD49e, OCT4, CD-105 and STRO-1 by immunohistochemistry.
CONCLUSION
This study establishes the efficacy of this 3D-TGP platform for clinically useable tissue-engineered cartilage for improvising the clinical outcome of cell therapy for cartilage repair.
目的
我们评估了使用三维（3D）热可逆凝胶化聚合物（TGP）培养的骨关节炎组织来源软骨细胞中干/祖细胞生物标志物的表达。
方法
使用3D-TGP培养从老年骨关节炎患者废弃活检组织中获取的软骨细胞，培养时间长达六周。
结果
软骨细胞以组织样方式生长，未分化为成纤维细胞，通过免疫组织化学证明，如此构建的组织工程化细胞对CD49e、OCT4、CD-105和STRO-1呈阳性。
结论
本研究确立了该3D-TGP平台用于临床可用的组织工程化软骨以改善软骨修复细胞治疗临床效果的有效性。
