    [Abstract]

    Recent popularization of next-generation sequencing enables conducting easy transcriptome analysis. Nevertheless, substantial RNA isolation work prior to RNA sequencing, as well as the high cost involved, still makes the routine use of large-scale transcriptome analysis difficult. For example, conventional phenol-chloroform RNA extraction cannot

    Isolation of Myofibres and Culture of Muscle Stem Cells from Adult Zebrafish
    成年斑马鱼肌纤维的分离和肌肉干细胞的培养

    [Abstract]

    Skeletal muscles generate force throughout life and require maintenance and repair to ensure efficiency. The population of resident muscle stem cells (MuSCs), termed satellite cells, dwells beneath the basal lamina of adult myofibres and contributes to both muscle growth and regeneration. Upon exposure to activating signals, MuSCs proliferate to

    In situ Hybridization of miRNAs in Human Embryonic Kidney and Human Pluripotent Stem Cell-derived Kidney Organoids
    在人胚肾和人多能干细胞衍生的肾类器官中微小RNA的原位杂交

    [Abstract]

    MicroRNAs are small RNAs that negatively regulate gene expression and play an important role in fine-tuning molecular pathways during development. There is increasing interest in studying their function in the kidney, but the majority of studies to date use kidney cell lines and assess the total amounts of miRNAs of interest either by qPCR or by

    [Abstract]

    Maintenance of DNA integrity is of pivotal importance for cells to circumvent detrimental processes that can ultimately lead to the development of various diseases. In the face of a plethora of endogenous and exogenous DNA-damaging agents, cells have evolved a variety of DNA repair mechanisms that are responsible for safeguarding genetic

    Preparation of Drosophila Larval Blood Cells for Single-cell RNA Sequencing
    果蝇幼虫血细胞单细胞RNA测序的制备

    [Abstract]

    Recent advances in single-cell RNA-sequencing (scRNA-seq) technologies provide unprecedented opportunities to identify new cell types and characterize cell states. One of the most important requirements for performing scRNA-seq is to obtain high-quality single cells in suspension. Recently, we used this approach to characterize Drosophila blood

    Mouse Periosteal Cell Culture, in vitro Differentiation, and in vivo Transplantation in Tibial Fractures
    小鼠骨膜细胞培养、体外分化及胫骨骨折的体内移植

    [Abstract]

    The periosteum covering the outer surface of bone contains skeletal stem/progenitor cells that can efficiently form cartilage and bone during bone repair. Several methods have been described to isolate periosteal cells based on bone scraping and/or enzymatic digestion. Here, we describe an explant culture method to isolate periosteum-derived

    Isolation of First-Trimester and Full-term Human Placental Hofbauer Cells
    妊娠早期和足月人胎盘霍夫鲍尔细胞的分离
    作者:Anna Appios, Jake R. Thomas and Naomi McGovern日期:06/05/2021,浏览量:1716,Q&A: 0
    [Abstract]

    The placenta is the crucial organ that regulates the health of both mother and fetus during pregnancy. The human placenta is composed of villous tree-like structures that embed into the maternal decidua. Within the stroma of the villi resides a population of fetally-derived macrophages, the Hofbauer cells (HBC). HBC are the only fetal immune cells

    Analysis of Monocyte Cell Fate by Adoptive Transfer in a Murine Model of TLR7-induced Systemic Inflammation
    TLR7诱导的系统性炎症小鼠模型中通过过继转移单核细胞命运分析

    [Abstract]

    Myeloid plasticity is a hallmark of the innate immune response to Toll-like receptor (TLR) activation. Here, we provide a protocol for monocyte cell fate tracking by adoptive transfer in the context of systemic inflammation induced by TLR7 activation, the principal innate immune receptor sensing viral RNA in mice. Defined monocyte subsets are

    Identification of R-loop-forming Sequences in Drosophila melanogaster Embryos and Tissue Culture Cells Using DRIP-seq
    DRIP-seq法鉴定黑腹果蝇胚胎和组织培养细胞R-loop形成序列
    作者:Célia Alecki and Nicole J. Francis日期:05/05/2021,浏览量:2946,Q&A: 0
    [Abstract]

    R-loops are non-canonical nucleic structures composed of an RNA–DNA hybrid and a displaced ssDNA. Originally identified as a source of genomic instability, R-loops have been shown over the last decade to be involved in the targeting of proteins and to be associated with different histone modifications, suggesting a regulatory function. In

    A Workflow for High-pressure Freezing and Freeze Substitution of the Caenorhabditis elegans Embryo for Ultrastructural Analysis by Conventional and Volume Electron Microscopy
    用常规和体积电子显微镜对秀丽隐杆线虫胚胎进行超微结构分析的高压冷冻和冷冻替代的工作流程

    [Abstract]

    The free-living nematode Caenorhabditis elegans is a popular model system for studying developmental biology. Here we describe a detailed protocol to high-pressure freeze the C. elegans embryo (either ex vivo after dissection, or within the intact worm) followed by quick freeze substitution. Processed samples are suitable for ultrastructural
