| 1 | Differentiation and Pro-Angiogenic Potential of Infantile Hemangioma Stem Cells显示文摘Objectives Infantile hemangioma(IH)is defined as a benign vascular tumor composed of immature vascular endothelial cells,with the unique characteristics of rich vascularization and self-regression into fibro-fatty tissue.CD133-positive hemangioma stem cells(HemSCs),present in the proliferating IH tissue,can be used to establish the IH animal model,which has highlighted the pathogenesis of IH in recent years.This study focused on the biological characteristics and differentiation capacity of HemSCs and aimed to provide a theoretical possibility for its application in tissue engineering.Methods To further confirm our hypothesis,we used fluorescence-activated cell sorting(FACS),in vitro multipotent induced differentiation,angiogenesis assay,and antibody array to identify the surface markers,multipotent differential potential,angiogenesis potential,and secreted factors of HemSCs,respectively,utilizing human adipose stem cells(hADSCs)as the control.Results We successfully isolated and cultured HemSCs.FACS indicated that,on average,more than 80%of HemSCs matched the criteria of mesenchymal stem cell(MSC)surface markers.Our results confirmed that HemSCs could differentiate into adipocytes,osteocytes,and chondrocytes.Additionally,compared with fibroblasts or hADSCs,HemSCs could promote angiogenesis through para-secretion.Conclusions HemSCs may originate from normal MSCs,and owing to their powerful proliferative and angiogenic abilities,they could be considered an IH pathogenic factor.These characteristics demonstratet heir potential as a candidate seed cell in tissue engineering. | Hanru YING Qianyi CHEN Xuanfeng CHEN Zhang YU MD Shih-Jen CHANG Lei CHANG Gang MA Yajing QIU Hui CHEN Xiaoxi LIN | 2020 | Chinese Journal Of Plastic and Reconstructive Surgery2020，2，1： | 2 |
| 2 | Theoretical investigation of core mode cut-off condition for tapered multicore fiber显示文摘Core mode cutoff is a useful concept not only for a tapered single-core fiber(SCF) but also for a tapered multicore fiber(MCF) to realize cladding mode transmission. In this paper, cut-off conditions of either core mode for tapered SCFs or supermodes for MCFs are theoretically investigated. Rigorous analytical formulas are derived for the modes of SCF by a three-layer waveguide model, and an approximation formula of the cut-off condition is given for the LP01 mode. The supermodes of MCFs are analyzed by the coupling mode theory, and the cut-off condition is calculated by a numerical method. Simulation results show that the in-phase supermode of MCFs has a similar cut-off condition with that of SCF. Based on this property, a convenient approximate formula is given to estimate the cut-off condition of the in-phase supermode for tapered MCFs. | Xuanfeng Zhou Zilun Chen Hang Zhou Jing Hou | 2015 | Photonics Research2015，3，5： | 1 |

| 4 | Air-stable inorganic solid-state electrolytes for high energy density lithium batteries: Challenges, strategies, and prospects显示文摘Solid-state batteries have been considered as promising next-generation energy storage devices for potentially higher energy density and better safety compared with commercial lithium-ion batteries that are based on organic liquid electrolytes.However,in terms of indispensable solid-state electrolytes,there are remaining issues to be solved before entering the market.Most solid-state electrolytes are air-sensitive,which causes a complex and expensive cell assembly and impressible interface.Therefore,the solid-state electrolytes are expected to be atmosphere-stable,which will undoubtedly bring significant benefits to solid-state battery manufacturing.This review covers air-stabilityrelated issues of different types of inorganic solid-state electrolytes and the corresponding strategies.First,we provide an overview of solid-state electrolytes and solid-state batteries,including their history and advantages/disadvantages.Then,different types of solid-state electrolytes are selected as examples to illustrate the unfavorable interactions in air and the corresponding adverse effects.Next,according to recent advances,we summarize the effective strategies of constructing different types of air-stable inorganic solid-state electrolytes.Finally,perspectives on designing accessible air-stable solid-state electrolytes are provided,aiming to achieve the assembly of high-performance solid-state batteries in the atmosphere. | Xuanfeng Chen Zengqiang Guan Fulu Chu Zhichen Xue Feixiang Wu Yan Yu | 2022 | InfoMat2022，4，1： | 0 |
