    Detection of mRNA by Whole Mount in situ Hybridization and DNA Extraction for Genotyping of Zebrafish Embryos
    Authors:  Rachna Narayanan and Andrew C. Oates, date: 03/20/2019, view: 200, Q&A: 0
    In situ hybridization is used to visualize the spatial distribution of gene transcripts in tissues and in embryos, providing important information about disease and development. Current methods involve the use of complementary riboprobes ...
    Detection of mRNA by Whole Mount in situ Hybridization and DNA Extraction for Genotyping of Zebrafish Embryos
    Authors:  Rachna Narayanan and Andrew C. Oates, date: 03/20/2019, view: 200, Q&A: 0
    [Abstract] In situ hybridization is used to visualize the spatial distribution of gene transcripts in tissues and in embryos, providing important information about disease and development. Current methods involve the use of complementary riboprobes incorporating non-radioactive labels that can be detected by immunohistochemistry and coupled to ...
    An Improved Staining Method for Low Signal LacZ Reporter Detection in Mouse Embryos
    Authors:  Xiaopeng Shen, Feng Xu, Shen Wu, Meng Li, Jingyi Zhang, Rui Liang and Yu Liu, date: 03/05/2019, view: 168, Q&A: 0
    [Abstract] In many fields of biology, especially in the field of developmental biology, LacZ reporter staining is an approach used to monitor gene expression patterns. In the LacZ reporter system, the LacZ gene is inserted in the endogenous location of the target gene via gene knock-in or by constructing a transgenic cassette in ...
    High-resolution Immunoelectron Microscopy Techniques for Revealing Distinct Subcellular Type 1 Cannabinoid Receptor Domains in Brain
    [Abstract] Activation of type 1 cannabinoid (CB1) receptors by endogenous, exogenous (cannabis derivatives) or synthetic cannabinoids (i.e., CP 55.940, Win-2) has a wide variety of behavioral effects due to the presence of CB1 receptors in the brain. In situ hybridization and immunohistochemical techniques have been ...
    Heterochronic Phenotype Analysis of Hypodermal Seam Cells in Caenorhabditis elegans
    Authors:  Yon Ju Ji and Jiou Wang, date: 01/05/2019, view: 667, Q&A: 0
    [Abstract] Heterochrony refers to changes in the timing of developmental events, and it is precisely regulated in the organisms by the heterochronic genes such as C. elegans lin-4 and let-7. Mutations in these genes cause precocious or retarded development of certain cell lineages. With well-defined cell lineages, C. elegans ...
    Quantification of Mouse Hematopoietic Progenitors’ Formation Using Time-lapse Microscopy and Image Analysis
    [Abstract] In vitro differentiation of mouse embryonic stem cells (mESCs) towards blood cells constitutes a well-established system to study the endothelial-to-hematopoietic transition (EHT) at the onset of blood development. Assessing the emergence of small non-adherent round blood cells in the culture without disturbing it is essential to evaluate ...
    Cartilage Induction from Mouse Mesenchymal Stem Cells in High-density Micromass Culture
    [Abstract] Mesenchymal stem cells have the ability to differentiate into multiple lineages, including adipocytes, osteoblasts and chondrocytes. Mesenchymal stem cells can be induced to differentiate into chondrocytes in extracellular matrices, such as alginate or collagen gel. Mesenchymal stem cells in a cell pellet or micromass culture can be also induced ...
    Notochord Injury Assays that Stimulate Transcriptional Responses in Zebrafish Larvae
    [Abstract] Zebrafish have become an increasingly important model organism in the field of wound healing and regenerative medicine, due to their high regenerative capacity coupled with high-resolution imaging in living animals. In a recent study, we described multiple physical and chemical methods to induce notochord injury that led to highly specific ...
    A Functionally Robust Phenotypic Screen that Identifies Drug Resistance-associated Genes Using 3D Cell Culture
    Authors:  Sun-Young Lee and Mina J. Bissell, date: 11/20/2018, view: 1065, Q&A: 0
    [Abstract] Drug resistance is a major obstacle in cancer treatment: A case in point is the failure of cancer patients to respond to tyrosine kinase inhibitors (TKI) of EGFR, a receptor that is highly expressed in many cancers. Identification of the targets and delineation of mechanisms of drug resistance remain major challenges. Traditional pharmacological ...
    Electron Microscopic Detection of Proteins and Protein Complexes in Mammalian Cells Using APEX-tagged, Conditionally Stable Nanobodies
    Authors:  Thomas E. Hall, James Rae, Nicholas Ariotti and Robert G. Parton, date: 11/20/2018, view: 791, Q&A: 0
    [Abstract] The recent development of 3D electron microscopic techniques for cells and tissues has necessitated the development of new methods for the detection of proteins and protein-complexes in situ. The development of new genetic tags, such as the ascorbate peroxidase, APEX, for electron microscopic detection of tagged proteins has expanded the ...
    Mosaic Labeling and 3-Dimensional Morphological Analysis of Single Cells in the Zebrafish Left-right Organizer
    Authors:  Agnik Dasgupta, Andrew E. Jacob and Jeffrey D. Amack, date: 11/20/2018, view: 760, Q&A: 0
    [Abstract] A transient epithelial structure called the left-right organizer (LRO) establishes left-right asymmetry in vertebrate embryos. Developmental defects that alter LRO formation result in left-right patterning errors that often lead to congenital heart malformations. However, little is known about mechanisms that regulate individual cell behaviors ...
