| 1 | Human placenta-derived mesenchymal stem cells loaded on linear ordered collagen scaffold improves functional recovery after completely transected spinal cord injury in canine显示文摘Traumatic spinal cord injury(SCI) is a major challenge in the clinic. In this study, we sought to examine the synergistic effects of linear ordered collagen scaffold(LOCS) and human placenta-derived mesenchymal stem cells(hPMSCs) when transplanted into completely transected beagle dogs. After 36 weeks observation, we found that LOCS+hPMSCs implants promoted better hindlimb locomotor recovery than was observed in the non-treatment(control) group and LOCS group. Histological analysis showed that the regenerated tissue after treatment was well integrated with the host tissue, and dramatically reduced the volume of cystic and chondroitin sulfate proteoglycans(CSPGs) expression. Furthermore, the LOCS+hPMSCs group also showed more neuron-specific βIII-tubulin(Tuj-1)-and NeuN-positive neurons in the lesion area, as well as axonal regeneration, remyelination and synapse formation in the lesion site. Additionally, dogs in the LOCS+hPMSCs group experienced enhanced sprouting of both ascending(CGRP-positive) sensory fibers and descending(5-HT-and TH-positive) motor fibers at the lesion area. All these data together suggested that the combined treatment had beneficial effects on neuronal regeneration and functional improvement in a canine complete transection model. Therefore, LOCS+hPMSCs implantation holds a great promise for bridging the nerve defect and may be clinically useful in the near future. | Sufang Han Zhifeng Xiao Xing Li Huan Zhao Bin Wang Zhixue Qiu Zhi Li Xin Mei Bai Xu Caixia Fan Bing Chen Jin Han Yanzheng Gu Huilin Yang Qin Shi Jianwu Dai | 2018 | Science China(Life Sciences)2018，61，1： | 15 |
| 2 | CD4^(+)CD25^(+)but not CD4^(+)Foxp3^(+) T cells as a regulatory subset in primary biliary cirrhosis显示文摘Increasing evidence indicates a role for regulatory T cells(Tregs)in the immune response and in autoimmune diseases,but the role of Tregs and cytokines in autoimmune hepatic diseases remains largely unclear and controversial,especially in patients with primary biliary cirrhosis(PBC).This study was undertaken to investigate Tregs and different cytokines in the liver and peripheral blood of PBC patients.We found that these patients demonstrated a reduction of CD4^(+)CD25^(+) T cells but elevated CD4^(+)Foxp3^(+) T cells in peripheral blood mononuclear cells(PBMCs)and CD41 T cells.The percentage of CD4^(+)CD25^(+) T cells in PBMCs was negatively correlated with elevated plasma interferon(IFN)-c levels.A liver-specific analysis showed that the frequency of Foxp31 Tregs,transforming growth factor(TGF)-b1 and IFN-c were increased in PBC patients.Our findings suggest that an imbalance between CD4^(+)CD25^(+) Tregs and cytotoxic cytokines plays a crucial role in the pathogenesis of PBC while the role of Foxp3 needs further investigation. | Dandan Wang Huayong Zhang Jun Liang Zhifeng Gu Qiang Zhou Xiangshan Fan Yayi Hou Lingyun Sun | 2010 | Cellular & Molecular Immunology2010，7，6： | 9 |

| 4 | Single-cell RNA sequencing reveals Nestin+active neural stem cells outside the central canal after spinal cord injury显示文摘Neural stem cells(NSCs)in the spinal cord hold great potential for repair after spinal cord injury(SCI).The ependyma in the central canal(CC)region has been considered as the NSCs source in the spinal cord.However,the ependyma function as NSCs after SCI is still under debate.We used Nestin as a marker to isolate potential NSCs and their immediate progeny,and characterized the cells before and after SCI by single-cell RNA-sequencing(scRNA-seq).We identified two subgroups of NSCs:the subgroup located within the CC cannot prime to active NSCs after SCI,while the subgroup located outside the CC were activated and exhibited the active NSCs properties after SCI.We demonstrated the comprehensive dynamic transcriptome of NSCs from quiescent to active NSCs after SCI.This study reveals that Nestin+cells outside CC were NSCs that activated upon SCI and may thus serve as endogenous NSCs for regenerative treatment of SCI in the future. | Muya Shu Xiaoyu Xue Hu Nie Xianming Wu Minghan Sun Lianyong Qiao Xing Li Bai Xu Zhifeng Xiao Yannan Zhao Yongheng Fan Bing Chen Jixiang Zhang Ya Shi Yaming Yang Falong Lu Jianwu Dai | 2022 | Science China(Life Sciences)2022，65，2： | 2 |
| 5 | Lineage tracing reveals the origin of Nestin-positive cells are heterogeneous and rarely from ependymal cells after spinal cord injury显示文摘Nestin is expressed extensively in neural stem/progenitor cells during neural development, but its expression is mainly restricted to the ependymal cells in the adult spinal cord. After spinal cord injury(SCI), Nestin expression is reactivated and Nestinpositive(Nestin;) cells aggregate at the injury site. However, the derivation of Nestin;cells is not clearly defined. Here, we found that Nestin expression was substantially increased in the lesion edge and lesion core after SCI. Using a tamoxifen inducible CreER(T2)-loxP system, we verified that ependymal cells contribute few Nestin;cells either to the lesion core or the lesion edge after SCI. In the lesion edge, GFAP+astrocytes were the main cell type that expressed Nestin;they then formed an astrocyte scar.In the lesion core, Nestin;cells expressed αSMA or Desmin, indicating that they might be derived from pericytes. Our results reveal that Nestin;cells in the lesion core and edge came from various cell types and rarely from ependymal cells after complete transected SCI, which may provide new insights into SCI repair. | Xiaoyu Xue Muya Shu Zhifeng Xiao Yannan Zhao Xing Li Haipeng Zhang Yongheng Fan Xianming Wu Bing Chen Bai Xu Yaming Yang Weiyuan Liu Sumei Liu Jianwu Dai | 2022 | Science China(Life Sciences)2022，65，4： | 2 |

| 9 | An invasive zone in human liver cancer identified by Stereo-seq promotes hepatocyte–tumor cell crosstalk,local immunosuppression and tumor progression显示文摘Dissecting and understanding the cancer ecosystem,especially that around the tumor margins,which have strong implications for tumor cell infiltration and invasion,are essential for exploring the mechanisms of tumor metastasis and developing effective new treatments.Using a novel tumor border scanning and digitization model enabled by nanoscale resolution-SpaTial Enhanced REsolution Omics-sequencing(Stereo-seq),we identified a 500µm-wide zone centered around the tumor border in patients with liver cancer,referred to as“the invasive zone”.We detected strong immunosuppression,metabolic reprogramming,and severely damaged hepatocytes in this zone.We also identified a subpopulation of damaged hepatocytes with increased expression of serum amyloid A1 and A2(referred to collectively as SAAs)located close to the border on the paratumor side.Overexpression of CXCL6 in adjacent malignant cells could induce activation of the JAK-STAT3 pathway in nearby hepatocytes,which subsequently caused SAAs’overexpression in these hepatocytes.Furthermore,overexpression and secretion of SAAs by hepatocytes in the invasive zone could lead to the recruitment of macrophages and M2 polarization,further promoting local immunosuppression,potentially resulting in tumor progression.Clinical association analysis in additional five independent cohorts of patients with primary and secondary liver cancer(n=423)showed that patients with overexpression of SAAs in the invasive zone had a worse prognosis.Further in vivo experiments using mouse liver tumor models in situ confirmed that the knockdown of genes encoding SAAs in hepatocytes decreased macrophage accumulation around the tumor border and delayed tumor growth.The identification and characterization of a novel invasive zone in human cancer patients not only add an important layer of understanding regarding the mechanisms of tumor invasion and metastasis,but may also pave the way for developing novel therapeutic strategies for advanced liver cancer and other solid tumors. | Liang Wu Jiayan Yan Yinqi Bai Feiyu Chen Xuanxuan Zou Jiangshan Xu Ao Huang Liangzhen Hou Yu Zhong Zehua Jing Qichao Yu Xiaorui Zhou Zhifeng Jiang Chunqing Wang Mengnan Cheng Yuan Ji Yingyong Hou Rongkui Luo Qinqin Li Liang Wu Jianwen Cheng Pengxiang Wang Dezhen Guo Waidong Huang Junjie Lei Shang Liu Yizhen Yan Yiling Chen Sha Liao Yuxiang Li Haixiang Sun Na Yao Xiangyu Zhang Shiyu Zhang Xi Chen Yang Yu Yao Li Fengming Liu Zheng Wang Shaolai Zhou Huanming Yang Shuang Yang Xun Xu Longqi Liu Qiang Gao Zhaoyou Tang Xiangdong Wang Jian Wang Jia Fan Shiping Liu Xinrong Yang Ao Chen Jian Zhou | 2023 | Cell Research2023，33，8： | 1 |

| 20 | Acute and Sub-Acute Toxicological Evaluations of Bioactive Alkaloidal Extract from Melodinus henryi and Their Main Chemical Constituents显示文摘Melodinus henryi is a good source of terpenoid indole alkaloids,and traditionally used as a folk medicine in the treatment of meningitis and fracture.In order to further exploit their potential uses,its anti-inflammatory and immunosuppressive activi-ties,safety evaluations and chemical profiles have been illustrated.Compared to the crude methanol extract from M.henryi and its non-alkaloidal fraction,the total alkaloidal fraction(MHTA)had the strongest anti-inflammatory and immunosup-pressive activities.In the acute oral toxicity assay,the half lethal dose(LD50)of MHTA was more than 2000 mg/kg.The sub-acute toxicity assay for consecutive 28 days exhibited MHTA at a lower concentrations of less than 500 mg/kg might be regarded as safe,and might damage spleen,liver,kidney,and heart when the dose is higher than 1000 mg/kg.In addition,a phytochemical investigation on MHTA led to the isolation of 15 monoterpenoid indole alkaloids.Thus,in regard with the potent side effects of MHTA,it should be used with caution in the development of phytomedicine. | Meilian Yang Yudan Wang Zhifeng Fan Qingwang Xue Guy Sedar Singor Njateng Yaping Liu Jianxin Cao Tianrui Zhao Guiguang Cheng | 2020 | Natural Products and Bioprospecting2020，10，4： | 1 |
