    [Abstract]

    Rodent cages equipped with access to a voluntary running wheel are commonly used to study the effects of aerobic physical activity on physiology and behavior. Notable discoveries in exercise neurobiology, including the key role of brain-derived neurotrophic factor (BDNF) in neural plasticity and cognition, have been made using rodents housed with

    Rice Root Hair Phenotypes Imaged by Cryo-SEM
    水稻根毛表型的低温扫描电镜成像
    [Abstract]

    Cryo-scanning electron microscopy (cryo-SEM) was first introduced for scientific use in the 1980s. Since then, cryo-SEM has become a routine technique for studying the surfaces and internal structures of biological samples with a high water content. In contrast to traditional SEM, cryo-SEM requires no sample pretreatment processes; thus, we can

    Quantitation of Secretory Granule Size in Drosophila Larval Salivary Glands
    果蝇幼虫唾液腺分泌颗粒大小的定量研究
    作者:Cheng-I J. Ma and Julie A. Brill日期:06/05/2021,浏览量:1141,Q&A: 0
    [Abstract]

    Maturation of secretory granules is a crucial process that ensures the bioactivity of cargo proteins undergoing regulated secretion. In Drosophila melanogaster, the larval salivary glands produce secretory granules that are up to four-fold larger in cross-sectional area after maturation. Therefore, we developed a live imaging microscopy approach

    Visualization and Quantitation of Wg trafficking in the Drosophila Wing Imaginal Epithelium
    果蝇翅成虫上皮中Wg运输的可视化和定量研究
    作者:Leonie Witte, Karen Linnemannstöns, Mona Honemann-Capito and Julia Christina Gross日期:06/05/2021,浏览量:1185,Q&A: 0
    [Abstract]

    Secretory Wnt trafficking can be studied in the polarized epithelial monolayer of Drosophila wing imaginal discs (WID). In this tissue, Wg (Drosophila Wnt-I) is presented on the apical surface of its source cells before being internalized into the endosomal pathway. Long-range Wg secretion and spread depend on secondary secretion from endosomal

    Generation of Mouse Pluripotent Stem Cell-derived Trunk-like Structures: An in vitro Model of Post-implantation Embryogenesis
    小鼠多能干细胞衍生干细胞样结构的生成:植入术后胚胎发生的体外模型
    [Abstract]

    Post-implantation mammalian embryogenesis involves profound molecular, cellular, and morphogenetic changes. The study of these highly dynamic processes is complicated by the limited accessibility of in utero development. In recent years, several complementary in vitro systems comprising self-organized assemblies of mouse embryonic stem cells, such

    Production of Phenotypically Uniform Human Cerebral Organoids from Pluripotent Stem Cells
    从多能干细胞生产表型一致的人类大脑类器官

    [Abstract]

    Recent advances in stem cell technology have allowed researchers to generate 3D cerebral organoids (COs) from human pluripotent stem cells (hPSCs). Indeed, COs have provided an unprecedented opportunity to model the developing human brain in a 3D context, and in turn, are suitable for addressing complex neurological questions by leveraging

    Automated Analysis of Cerebrospinal Fluid Flow and Motile Cilia Properties in The Central Canal of Zebrafish Embryos
    斑马鱼胚胎中央管中脑脊液流动和运动纤毛特性的自动分析

    [Abstract]

    Circulation of cerebrospinal fluid (CSF) plays an important role during development. In zebrafish embryo, the flow of CSF has been found to be bidirectional in the central canal of the spinal cord. In order to compare conditions and genetic mutants across each other, we recently automated the quantification of the velocity profile of exogenous

    Live Intravital Intestine with Blood Flow Visualization in Neonatal Mice Using Two-photon Laser Scanning Microscopy
    用双光子激光扫描显微镜观察新生小鼠活体肠内血流
    [Abstract]

    This protocol describes a novel technique to investigate the microcirculation dynamics underlying the pathology in the small intestine of neonatal mice using two-photon laser-scanning microscopy (TPLSM). Recent technological advances in multi-photon microscopy allow intravital analysis of different organs such as the liver, brain and intestine.

    Optimized Immunostaining of Embryonic and Early Postnatal Mouse Brain Sections

    [Abstract]

    The mammalian neocortex, the outer layer of the cerebrum and most recently evolved brain region, is characterized by its unique areal and laminar organization. Distinct cortical layers and areas can be identified by the protein expression of graded transcription factors and molecular determinants that define the identity of different projection

    Measuring Bone Volume at Multiple Densities by Micro-computed Tomography

    [Abstract]

    Bone strength is controlled by both bone mass, and the organization and quality of the bone material. The current standard method for measuring bone mass in mouse and rat studies is micro-computed tomography. This method typically uses a single threshold to identify bone material in the cortical and trabecular regions. However, this single
