1Epidermal Patterning Genes Impose Non‐cell Autonomous Cell Size Determination and have Additional Roles in Root Meristem Size Control显示文摘The regulation of cellular growth is of vital importance for embryonic and postembryonic patterning.Growth regulation in the epidermis has importance for organ growth rates in roots and shoots,proposing epidermal cells as an interesting model for cellular growth regulation.Here we assessed whether the root epidermis is a suitable model system to address cell size determination.In Arabidopsis thaliana L.,root epidermal cells are regularly spaced in neighbouring tricho‐(root hair)and atrichoblast(non‐hair)cells,showing already distinct cell size regulation in the root meristem.We determined cell sizes in the root meristem and at the onset of cellular elongation,revealing that not only division rates but also cellular shape is distinct in tricho‐and atrichoblasts.Intriguingly,epidermal‐patterning mutants,failing to defne differential vacuolization in neighbouring epidermal cell fles,also display non‐differential growth.Using these epidermal‐patterning mutants,we show that polarized growth behaviour of epidermal tricho‐and atrichoblast is interdependent,suggesting non‐cell autonomous signals to integrate tissue expansion.Besides the interweaved cell‐type‐dependent growth mechanism,we reveal an additional role for epidermal patterning genes in root meristem size and organ growth regulation.We conclude that epidermal cells represent a suitable model system to study cell size determination and interdependent tissue growth.Christian Lfke Kai Dünser Jürgen Kleine‐Vehn 2013Journal of Integrative Plant Biology2013,55,9:3
2Panda X-III: Searching for neutrinoless double beta decay with high pressure ^(136)Xe gas time projection chambers显示文摘Searching for the neutrinoless double beta decay(NLDBD)is now regarded as the topmost promising technique to explore the nature of neutrinos after the discovery of neutrino masses in oscillation experiments.Panda X-III(particle and astrophysical xenon experiment III)will search for the NLDBD of136Xe at the China Jin Ping Underground Laboratory(CJPL).In the first phase of the experiment,a high pressure gas Time Projection Chamber(TPC)will contain 200 kg,90%136Xe enriched gas operated at10 bar.Fine pitch micro-pattern gas detector(Microbulk Micromegas)will be used at both ends of the TPC for the charge readout with a cathode in the middle.Charge signals can be used to reconstruct the electron tracks of the NLDBD events and provide good energy and spatial resolution.The detector will be immersed in a large water tank to ensure~5 m of water shielding in all directions.The second phase,a ton-scale experiment,will consist of five TPCs in the same water tank,with improved energy resolution and better control over backgrounds.Xun Chen Chang Bo Fu Javier Galan Karl Giboni Franco Giuliani Ling Hui Gu Ke Han Xiang Dong Ji Heng Lin Jiang Lai Liu Kai Xiang Ni Hiroki Kusano Xiang Xiang Ren Shao Bo Wang Yong Yang Dan Zhang Tao Zhang Li Zhao Xiang Ming Sun Shou Yang Hu Si Yu Jian Xing Long Li Xiao Mei Li Hao Liang Huan Qiao Zhang Ming Rui Zhao Jing Zhou Ya Jun Mao Hao Qiao Si Guang Wang Ying Yuan Meng Wang Amir N.Khan Neill Raper Jian Tang Wei Wang Jia Ning Dong Chang Qing Feng Cheng Li Jian Bei Liu Shu Bin Liu Xiao Lian Wang Dan Yang Zhu Juan F.Castel Susana Cebri'an Theopisti Dafni Javier G.Garza Igor G.Irastorza Francisco J.Iguaz Gloria Luz ′on Hector Mirallas Stephan Aune Eric Berthoumieux Yann Bedfer Denis Calvet Nicole d'Hose Alain Delbart Maria Diakaki Esther Ferrer-Ribas Andrea Ferrero Fabienne Kunne Damien Neyret Thomas Papaevangelou Franck Sabatie Maxence Vanderbroucke AnDi Tan Wick Haxton Yuan Mei Chinorat Kobdaj Yu-Peng Yan 2017Science China(Physics,Mechanics & Astronomy)2017,60,6:2
3Integrated dynamic wet spinning of core-sheath hydrogel fibers for optical-to-brain/tissue communications显示文摘Hydrogel optical light-guides have received substantial interest for applications such as deep-tissue biosensors,optogenetic stimulation and photomedicine due to their biocompatibility,(micro)structure control and tissue-like Young’s modulus.However,despite recent developments,large-scale fabrication with a continuous synthetic methodology,which could produce core-sheath hydrogel fibers with the desired optical and mechanical properties suitable for deep-tissue applications,has yet to be achieved.In this study,we report a versatile concept of integrated light-triggered dynamic wet spinning capable of continuously producing core-sheath hydrogel optical fibers with tunable fiber diameters,and mechanical and optical propagation properties.Furthermore,this concept also exhibited versatility for various kinds of core-sheath functional fibers.The wet spinning synthetic procedure and fabrication process were optimized with the rational design of the core/sheath material interface compatibility[core=poly(ethylene glycol diacrylate-co-acrylamide);sheath=Ca-alginate],optical transparency,refractive index and spinning solution viscosity.The resulting hydrogel optical fibers exhibited desirable low optical attenuation(0.18±0.01 d B cm^(-1) with 650 nm laser light),excellent biocompatibility and tissue-like Young’s modulus(<2.60 MPa).The optical waveguide hydrogel fibers were successfully employed for deep-tissue cancer therapy and brain optogenetic stimulation,confirming that they could serve as an efficient versatile tool for diverse deep-tissue therapy and brain optogenetic applications.Guoyin Chen Gang Wang Xinrong Tan Kai Hou Qingshuo Meng Peng Zhao Shun Wang Jiayi Zhang Zhan Zhou Tao Chen Yanhua Cheng D Benjamin S.Hsiao Elsa Reichmanis Meifang Zhu 2021National Science Review2021,8,9:2
