| 2 | A high-resolution route map reveals distinct stages of chondrocyte dedifferentiation for cartilage regeneration显示文摘Articular cartilage damage is a universal health problem.Despite recent progress,chondrocyte dedifferentiation has severely compromised the clinical outcomes of cell-based cartilage regeneration.Loss-of-function changes are frequently observed in chondrocyte expansion and other pathological conditions,but the characteristics and intermediate molecular mechanisms remain unclear.In this study,we demonstrate a time-lapse atlas of chondrocyte dedifferentiation to provide molecular details and informative biomarkers associated with clinical chondrocyte evaluation.We performed various assays,such as single-cell RNA sequencing(scRNA-seq),live-cell metabolic assays,and assays for transposase-accessible chromatin with high-throughput sequencing(ATAC-seq),to develop a biphasic dedifferentiation model consisting of early and late dedifferentiation stages.Early-stage chondrocytes exhibited a glycolytic phenotype with increased expression of genes involved in metabolism and antioxidation,whereas late-stage chondrocytes exhibited ultrastructural changes involving mitochondrial damage and stress-associated chromatin remodeling.Using the chemical inhibitor BTB06584,we revealed that early and late dedifferentiated chondrocytes possessed distinct recovery potentials from functional phenotype loss.Notably,this two-stage transition was also validated in human chondrocytes.An image-based approach was established for clinical use to efficiently predict chondrocyte plasticity using stage-specific biomarkers.Overall,this study lays a foundation to improve the quality of chondrocytes in clinical use and provides deep insights into chondrocyte dedifferentiation. | Yishan Chen Yeke Yu Ya Wen Juan Chen Junxin Lin Zixuan Sheng Wenyan Zhou Heng Sun Chengrui An Jiansong Chen Weiliang Wu Chong Teng Wei Wei Hongwei Ouyang | 2022 | Bone Research2022，10，3： | 1 |
