| 1 | Construction of a small-caliber tissue-engineered blood vessel using icariin-loaded β-cyclodextrin sulfate for in situ anticoagulation and endothelialization显示文摘The rapid endothelialization of tissue-engineered blood vessels(TEBVs) can effectively prevent thrombosis and inhibit intimal hyperplasia. The traditional Chinese medicine ingredient icariin is highly promising for the treatment of cardiovascular diseases.β-cyclodextrin sulfate is a type of hollow molecule that has good biocompatibility and anticoagulation properties and exhibits a sustained release of icariin. We studied whether icariin-loaded β-cyclodextrin sulfate can promote the endothelialization of TEBVs. The experimental results showed that icariin could significantly promote the proliferation and migration of endothelial progenitor cells; at the same time, icariin could promote the migration of rat vascular endothelial cells(RAVECs). Subsequently,we used an electrostatic force to modify the surface of the TEBVs with icariin-loaded β-cyclodextrin sulfate, and these vessels were implanted into the rat common carotid artery. After 3 months, micro-CT results showed that the TEBVs modified using icariin-loaded β-cyclodextrin sulfate had a greater patency rate. Scanning electron microscopy(SEM) and CD31 immunofluorescence results showed a better degree of endothelialization. Taken together, icariin-loaded β-cyclodextrin sulfate can achieve anticoagulation and rapid endothelialization of TEBVs to ensure their long-term patency. | Jingyuan Yang Keyu Wei Yeqin Wang Yanzhao Li Ning Ding Da Huo Tianran Wang Guanyuan Yang Mingcan Yang Tan Ju Wen Zeng Chuhong Zhu | 2018 | Science China(Life Sciences)2018，61，10： | 5 |
| 2 | CCR10 and its ligands in regulation of epithelial immunity and diseases显示文摘Epithelial tissues covering the external and internal surface of a body are constantly under physical,chemical or biological assaults.To protect the epithelial tissues and maintain their homeostasis,multiple layers of immune defense mechanisms are required.Besides the epithelial tissue-resident immune cells that provide the first line of defense,circulating immune cells are also recruited into the local tissues in response to challenges.Chemokines and chemokine receptors regulate tissue-specific migration,maintenance and functions of immune cells.Among them,chemokine receptor CCR10 and its ligands chemokines CCL27 and CCL28 are uniquely involved in the epithelial immunity.CCL27 is expressed predominantly in the skin by keratinocytes while CCL28 is expressed by epithelial cells of various mucosal tissues.CCR10 is expressed by various subsets of innate-like T cells that are programmed to localize to the skin during their developmental processes in the thymus.Circulating T cells might be imprinted by skin-associated antigen-presenting cells to express CCR10 for their recruitment to the skin during the local immune response.On the other hand,IgA antibody-producing B cells generated in mucosa-associated lymphoid tissues express CCR10 for their migration and maintenance at mucosal sites.Increasing evidence also found that CCR10/ligands are involved in regulation of other immune cells in epithelial immunity and are frequently exploited by epithelium-localizing or-originated cancer cells for their survival,proliferation and evasion from immune surveillance.Herein,we review current knowledge on roles of CCR10/ligands in regulation of epithelial immunity and diseases and speculate on related important questions worth further investigation. | Na Xiong Yaoyao Fu Shaomin Hu Mingcan Xia Jie Yang | 2012 | Protein & Cell2012，3，8： | 5 |
| 3 | Engineering hiPSC-CM and hiPSC-EC laden 3D nanofibrous splenic hydrogel for improving cardiac function through revascularization and remuscularization in infarcted heart显示文摘Cell therapy has been a promising strategy for cardiac repair after myocardial infarction(MI),but a poor ischemic environment and low cell delivery efficiency remain significant challenges.The spleen serves as a hematopoietic stem cell niche and secretes cardioprotective factors after MI,but it is unclear whether it could be used for human pluripotent stem cell(hiPSC)cultivation and provide a proper microenvironment for cell grafts against the ischemic environment.Herein,we developed a splenic extracellular matrix derived thermoresponsive hydrogel(SpGel).Proteomics analysis indicated that SpGel is enriched with proteins known to modulate the Wnt signaling pathway,cell-substrate adhesion,cardiac muscle contraction and oxidation-reduction processes.In vitro studies demonstrated that hiPSCs could be efficiently induced into endothelial cells(iECs)and cardiomyocytes(iCMs)with enhanced function on SpGel.The cytoprotective effect of SpGel on iECs/iCMs against oxidative stress damage was also proven.Furthermore,in vivo studies revealed that iEC/iCM-laden SpGel improved cardiac function and inhibited cardiac fibrosis of infarcted hearts by improving cell survival,revascularization and remuscularization.In conclusion,we successfully established a novel platform for the efficient generation and delivery of autologous cell grafts,which could be a promising clinical therapeutic strategy for cardiac repair and regeneration after MI. | Ge Guan Da Huo Yanzhao Li Xiaolin Zhao Yinghao Li Zhongliang Qin Dayu Sun Guanyuan Yang Mingcan Yang Ju Tan Wen Zeng Chuhong Zhu | 2021 | Bioactive Materials2021，6，12： | 2 |

| 5 | Surface etching induced ultrathin sandwich structure realizing enhanced photocatalytic activity显示文摘Photocatalytic conversion efficiency is limited by serious charge carrier recombination. Efficient carrier separation is usually achieved by elegantly-designed multi-component structures connected by directional electric field. Herein, we developed a twodimensional(2 D) sandwich structure, as a new photocatalytic system, to realize high-efficiency carrier separation. This strategy integrated multifunction into a single structure for the first time, which successfully introduces a stable built-in electric field,realizing high-effective carrier separation. Besides, the carrier concentration is dramatically increased due to dimensional confinement. Benefiting from above synergic advantages, 2 D sandwich photocatalyst achieves the highest nitrogen fixation rate(435 μmol g^(-1) h^(-1)) in inorganic solid photocatalysts under visible light irradiation. We anticipate that 2 D sandwich photocatalyst holds promises for the application and expansion of 2 D materials in photocatalysis research. | Bo Yang Wentuan Bi Yangyang Wan Xiaogang Li Mingcan Huang Ruilin Yuan Huanxin Ju Wangsheng Chu Xiaojun Wu Linghui He Changzheng Wu Yi Xie | 2018 | Science China Chemistry2018，61，12： | 1 |
| 6 | Programmable dual responsive system reconstructing nerve interaction with small-diameter tissue-engineered vascular grafts and inhibiting intimal hyperplasia in diabetes显示文摘Small-diameter tissue-engineered vascular grafts(sdTEVGs)with hyperglycemia resistance have not been constructed.The intimal hyperplasia caused by hyperglycemia remains problem to hinder the patency of sdTEVGs.Here,inspired by bionic regulation of nerve on vascular,we found the released neural exosomes could inhibit the abnormal phenotype transformation of vascular smooth muscle cells(VSMCs).The transformation was a prime culprit causing the intimal hyperplasia of sdTEVGs.To address this concern,sdTEVGs were modified with an on-demand programmable dual-responsive system of ultrathin hydrogels.An external primary Reactive Oxygen Species(ROS)-responsive Netrin-1 system was initially triggered by local inflammation to induce nerve remolding of the sdTEVGs overcoming the difficulty of nerve regeneration under hyperglycemia.Then,the internal secondary ATP-responsive DENND1A(guanine nucleotide exchange factor)system was turned on by the neurotransmitter ATP from the immigrated nerve fibers to stimulate effective release of neural exosomes.The results showed nerve fibers grow into the sdTEVGs in diabetic rats 30 days after transplantation.At day 90,the abnormal VSMCs phenotype was not detected in the sdTEVGs,which maintained long-time patency without intima hyperplasia.Our study provides new insights to construct vascular grafts resisting hyperglycemia damage. | Yanzhao Li Yeqin Wang Fangchao Xue Xuli Feng Zhaojing Ba Junjie Chen Zhenhua Zhou Yanhong Wang Ge Guan Guanyuan Yang Ziwei Xi Hao Tian Yong Liu Ju Tan Gang Li Xiewan Chen Mingcan Yang Wen Chen Chuhong Zhu Wen Zeng | 2022 | Bioactive Materials2022，7，1： | 0 |
| 7 | Preclinical evaluation of the safety and effectiveness of a new bioartificial cornea显示文摘Cross-linking agents are frequently used to restore corneal properties after decellularization,and it is especially important to select an appropriate method to avoid excessive cross-linking.In addition,how to promote wound healing and how to improve scar formation require further investigation.To ensure the safety and efficacy of animal-derived products,we designed bioartificial corneas(BACs)according to the criteria for Class III medical devices.Our BACs do not require cross-linking agents and increase mechanical strength via self-cross-linking of aldehyde-modified hyaluronic acid(AHA)and carboxymethyl chitosan(CMC)on the surface of decellularized porcine corneas(DPCs).The results showed that the BACs had good biocompatibility and transparency,and the modification enhanced their antibacterial and anti-inflammatory properties in vitro.Preclinical animal studies showed that the BACs can rapidly regenerate the epithelium and restore vision within a month.After 3 months,the BACs were gradually filled with epithelial,stromal,and neuronal cells,and after 6 months,their transparency and histology were almost normal.In addition,side effects such as corneal neovascularization,conjunctival hyperemia,and ciliary body hyperemia rarely occur in vivo.Therefore,these BACs show promise for clinical application for the treatment of infectious corneal ulcers and as a temporary covering for corneal perforations to achieve the more time. | Yansha Hao Jingting Zhou Ju Tan Feng Xiang Zhongliang Qin Jun Yao Gang Li Mingcan Yang Lingqin Zeng Wen Zeng Chuhong Zhu | 2023 | Bioactive Materials2023，，11： | 0 |
