| 1 | RANKL signaling in bone marrow mesenchymal stem cells negatively regulates osteoblastic bone formation显示文摘RANKL signaling is essential for osteoclastogenesis. Its role in osteoblastic differentiation and bone formation is unknown. Here we demonstrate that RANK is expressed at an early stage of bone marrow mesenchymal stem cells(BMSCs) during osteogenic differentiation in both mice and human and decreased rapidly. RANKL signaling inhibits osteogenesis by promoting β-catenin degradation and inhibiting its synthesis. In contrast, RANKL signaling has no significant effects on adipogenesis of BMSCs.Interestingly, conditional knockout of rank in BMSCs with Prx1-Cre mice leads to a higher bone mass and increased trabecular bone formation independent of osteoclasts. In addition, rank^(flox/flox): Prx1-Cre mice show resistance to ovariectomy-(OVX) induced bone loss. Thus, our results reveal that RANKL signaling regulates both osteoclasts and osteoblasts by inhibition of osteogenic differentiation of BMSCs and promotion of osteoclastogenesis. | Xiao Chen Xin Zhi Jun Wang Jiacan Su | 2018 | Bone Research2018，6，4： | 24 |
| 2 | Subchondral bone microenvironment in osteoarthritis and pain显示文摘Osteoarthritis comprises several joint disorders characterized by articular cartilage degeneration and persistent pain,causing disability and economic burden.The incidence of osteoarthritis is rapidly increasing worldwide due to aging and obesity trends.Basic and clinical research on osteoarthritis has been carried out for decades,but many questions remain unanswered.The exact role of subchondral bone during the initiation and progression osteoarthritis remains unclear.Accumulating evidence shows that subchondral bone lesions,including bone marrow edema and angiogenesis,develop earlier than cartilage degeneration.Clinical interventions targeting subchondral bone have shown therapeutic potential,while others targeting cartilage have yielded disappointing results.Abnormal subchondral bone remodeling,angiogenesis and sensory nerve innervation contribute directly or indirectly to cartilage destruction and pain.This review is about bone-cartilage crosstalk,the subchondral microenvironment and the critical role of both in osteoarthritis progression.It also provides an update on the pathogenesis of and interventions for osteoarthritis and future research targeting subchondral bone. | Yan Hu Xiao Chen Sicheng Wang Yingying Jing Jiacan Su | 2021 | Bone Research2021，9，3： | 24 |

| 4 | Exosome-guided bone targeted delivery of Antagomir-188 as an anabolic therapy for bone loss显示文摘The differentiation shift from osteogenesis to adipogenesis of bone marrow mesenchymal stem cells(BMSCs)characterizes many pathological bone loss conditions.Stromal cell-derived factor-1(SDF1)is highly enriched in the bone marrow for C-X-C motif chemokine receptor 4(CXCR4)-positive hematopoietic stem cell(HSC)homing and tumor bone metastasis.In this study,we displayed CXCR4 on the surface of exosomes derived from genetically engineered NIH-3T3 cells.CXCR4+exosomes selectively accumulated in the bone marrow.Then,we fused CXCR4+exosomes with liposomes carrying antagomir-188 to produce hybrid nanoparticles(NPs).The hybrid NPs specifically gathered in the bone marrow and released antagomir-188,which promoted osteogenesis and inhibited adipogenesis of BMSCs and thereby reversed age-related trabecular bone loss and decreased cortical bone porosity in mice.Taken together,this study presents a novel way to obtain bone-targeted exosomes via surface display of CXCR4 and a promising anabolic therapeutic approach for age-related bone loss. | Yan Hu Xiaoqun Li Qin Zhang Zhengrong Gu Ying Luo Jiawei Guo Xiuhui Wang Yingying Jing Xiao Chen Jiacan Su | 2021 | Bioactive Materials2021，6，9： | 12 |
| 5 | The horizon of bone organoid: A perspective on constructionand application显示文摘Bone defects repair and regeneration by various causes such as tumor resection, trauma, degeneration, etc. havealways been a key issue in the clinics. As one of the few organs that can regenerate after adulthood, bone itselfhas a strong regenerative ability. In recent decades, bone tissue engineering technology provides various types offunctional scaffold materials and seed cells for bone regeneration and repair, which significantly accelerates thespeed and quality of bone regeneration, and many clinical problems are gradually solved. However, the bonemetabolism mechanism is complicated, the research duration is long and difficult, which significantly restrictsthe progress of bone regeneration and repair research. Organoids as a new concept, which is built in vitro withthe help of tissue engineering technology based on biological theory, can simulate the complex biologicalfunctions of organs in vivo. Once proposed, it shows broad application prospects in the research of organdevelopment, drug screening, mechanism study, and so on. As a complex and special organ, bone organoidconstruction itself is quite challenging. This review will introduce the characteristics of bone microenvironment,the concept of organoids, focus on the research progress of bone organoids, and propose the strategies for boneorganoid construction, study direction, and application prospects. | Shuangshuang Chen Xiao Chen Zhen Geng Jiacan Su | 2022 | Bioactive Materials2022，7，12： | 9 |
| 6 | Melatonin lowers edema after spinal cord injury显示文摘Melatonin has been shown to diminish edema in rats. Melatonin can be used to treat spinal cord injury. This study presumed that melatonin could relieve spinal cord edema and examined how it might act. Our experiments found that melatonin(100 mg/kg, i.p.) could reduce the water content of the spinal cord, and suppress the expression of aquaporin-4 and glial fibrillary acidic protein after spinal cord injury. This suggests that the mechanism by which melatonin alleviates the damage to the spinal cord by edema might be related to the expression of aquaporin-4 and glial fibrillary acidic protein. | Cheng Li Xiao Chen Suchi Qiao Xinwei Liu Chang Liu Degang Zhu Jiacan Su Zhiwei Wang | 2014 | Neural Regeneration Research2014，9，24： | 5 |

| 8 | Bone/cartilage organoid on-chip:Construction strategy and application显示文摘The necessity of disease models for bone/cartilage related disorders is well-recognized,but the barrier between ex-vivo cell culture,animal models and the real human body has been pending for decades.The organoid-on-a-chip technique showed opportunity to revolutionize basic research and drug screening for diseases like osteoporosis and arthritis.The bone/cartilage organoid on-chip(BCoC)system is a novel platform of multi-tissue which faithfully emulate the essential elements,biologic functions and pathophysiological response under real circumstances.In this review,we propose the concept of BCoC platform,summarize the basic modules and current efforts to orchestrate them on a single microfluidic system.Current disease models,unsolved problems and future challenging are also discussed,the aim should be a deeper understanding of diseases,and ultimate realization of generic ex-vivo tools for further therapeutic strategies of pathological conditions. | Yan Hu Hao Zhang Sicheng Wang Liehu Cao Fengjin Zhou Yingying Jing Jiacan Su | 2023 | Bioactive Materials2023，，7： | 3 |
| 9 | Selection and identification of a novel ssDNA aptamer targeting human skeletal muscle显示文摘Skeletal muscle disorders have posed great threats to health.Selective delivery of drugs and oligonucleotides to skeletal muscle is challenging.Aptamers can improve targeting efficacy.In this study,for the first time,the human skeletal muscle-specific ssDNA aptamers(HSM01,etc.)were selected and identified with Systematic Evolution of Ligands by Exponential Enrichment(SELEX).The HSM01 ssDNA aptamer preferentially interacted with human skeletal muscle cells in vitro.The in vivo study using tree shrews showed that the HSM01 ssDNA aptamer specifically targeted human skeletal muscle cells.Furthermore,the ability of HSM01 ssDNA aptamer to target skeletal muscle cells was not affected by the formation of a disulfide bond with nanoliposomes in vitro or in vivo,suggesting a potential new approach for targeted drug delivery to skeletal muscles via liposomes.Therefore,this newly identified ssDNA aptamer and nanoliposome modification could be used for the treatment of human skeletal muscle diseases. | Shuming Sun Han Liu Yan Hu Yanpeng Wang Mingri Zhao Yijun Yuan Yafei Han Yingying Jing Jin Cui Xiaoxiang Ren Xiao Chen Jiacan Su | 2023 | Bioactive Materials2023，，2： | 3 |
| 10 | Bone/cartilage targeted hydrogel: Strategies and applications显示文摘The skeletal system is responsible for weight-bearing,organ protection,and movement.Bone diseases caused by trauma,infection,and aging can seriously affect a patient’s quality of life.Bone targeted biomaterials are suitable for the treatment of bone diseases.Biomaterials with bone-targeted properties can improve drug utilization and reduce side effects.A large number of bone-targeted micro-nano materials have been developed.However,only a few studies addressed bone-targeted hydrogel.The large size of hydrogel makes it difficult to achieve systematic targeting.However,local targeted hydrogel still has significant prospects.Molecules in bone/cartilage extracellular matrix and bone cells provide binding sites for bone-targeted hydrogel.Drug delivery systems featuring microgels with targeting properties is a key construction strategy for bone-targeted hydrogel.Besides,injectable hydrogel drug depot carrying bone-targeted drugs is another strategy.In this review,we summarize the bone-targeted hydrogel through application environment,construction strategies and disease applications.We hope this article will provide a reference for the development of bone-targeted hydrogels.We also hope this article could increase awareness of bone-targeted materials. | Hao Zhang Shunli Wu Weikai Chen Yan Hu Zhen Geng Jiacan Su | 2023 | Bioactive Materials2023，，5： | 2 |

| 17 | M2 macrophage-derived exosomes promote diabetic fracture healing by acting as an immunomodulator显示文摘Diabetes mellitus is a chronically inflamed disease that predisposes to delayed fracture healing.Macrophages play a key role in the process of fracture healing by undergoing polarization into either M1 or M2 subtypes,which respectively exhibit pro-inflammatory or anti-inflammatory functions.Therefore,modulation of macrophage polarization to the M2 subtype is beneficial for fracture healing.Exosomes perform an important role in improving the osteoimmune microenvironment due to their extremely low immunogenicity and high bioactivity.In this study,we extracted the M2-exosomes and used them to intervene the bone repair in diabetic fractures.The results showed that M2-exosomes significantly modulate the osteoimmune microenvironment by decreasing the proportion of M1 macrophages,thereby accelerating diabetic fracture healing.We further confirmed that M2-exosomes induced the conversion of M1 macrophages into M2 macrophages by stimulating the PI3K/AKT pathway.Our study offers a fresh perspective and a potential therapeutic approach for M2-exosomes to improve diabetic fracture healing. | Yili Wang Qiushui Lin Hao Zhang Sicheng Wang Jin Cui Yan Hu Jinlong Liu Mengmeng Li Kun Zhang Fengjin Zhou Yingying Jing Zhen Geng Jiacan Su | 2023 | Bioactive Materials2023，，10： | 0 |
