    Single Cell Migration Assay Using Human Breast Cancer MDA-MB-231 Cell Line
    Authors:  David M. Gau and Partha Roy, date: 04/20/2020, view: 1234, Q&A: 0
    [Abstract] Cell migration is a fundamental cellular process that plays a crucial role in many physioglogical and pathological processes such as wound healing or cancer metastasis. Many assays have been developed to examine cell migration, such as the wound healing or scratch assay, Boyden Chamber or transwell assay, and the method we will describe here, ...
    Analysis of Random Migration of Cancer Cells in 3D
    Authors:  Sai P. Visweshwaran and Alexis Gautreau, date: 01/05/2020, view: 1340, Q&A: 0
    [Abstract] The ability of cancer cells to migrate through a complex three-dimensional (3D) environment is a hallmark event of cancer metastasis. Therefore, an in vitro migration assay to evaluate cancer cell migration in a 3D setting is valuable to examine cancer progression. Here, we describe such a simple migration assay in a 3D ...
    Preparation of Actinoplanes missouriensis Zoospores and Assay for Their Adherence to Solid Surfaces
    Authors:  Takeaki Tezuka, Daisuke Nakane, Tomohiro Kimura and Yasuo Ohnishi, date: 12/20/2019, view: 748, Q&A: 0
    [Abstract] Spherical zoospores of a rare actinomycete, Actinoplanes missouriensis, adhere to various hydrophobic solid surfaces by means of type IV pili. The purpose of this protocol is to provide detailed descriptions of the preparation of A. missouriensis zoospores and an assay for the adhesion of the zoospores to solid surfaces. This ...
    Assessing Different Ways of Bacillus subtilis Spreading over Abiotic Surfaces
    Authors:  Marco Bartolini and Roberto Grau, date: 11/20/2019, view: 1403, Q&A: 0
    [Abstract] Surface-associate motility on biotic and abiotic environments is a key mechanism used by the model bacterium Bacillus subtilis and its closest relatives (i.e., B. amyloliquefaciens, B. thuringiensis, B. cereus, B. pumilus) for surface colonization and spreading across surfaces. The study of ...
    Explant Culture of the Embryonic Mouse Spinal Cord and Gene Transfer by ex vivo Electroporation
    [Abstract] Developing axons change responsiveness to guidance cues during the journey to synapse with target cells. Axon crossing at the ventral midline serves as a model for studying how axons accomplish such a switch in their response. Although primary neuron culture has been a versatile technique for elucidating various developmental mechanisms, many in ...
    Fibroblast Gap-closure Assay-Microscopy-based in vitro Assay Measuring the Migration of Murine Fibroblasts
    Authors:  Agnieszka P. Looney and Mallar Bhattacharya, date: 08/20/2019, view: 1736, Q&A: 0
    [Abstract] Pulmonary fibrosis is characterized by pathological scaring of the lung. Similar to other fibrotic diseases, scar formation is driven by excessive extracellular matrix deposition by activated, proliferative, and migratory fibroblasts.

    Currently, the two most widely used chemotaxis and cell migration assays are the scratch assay and the ...
    Live-cell Migration Assays to Study Motility of Neural and Glial (Oligodendrocyte) Progenitor Cells
    Authors:  Chu-Yen Chen, Fu-Sheng Chou and Pei-Shan Wang, date: 06/20/2019, view: 1918, Q&A: 0
    [Abstract] Cell motility has been extensively studied in in vitro models using fibroblasts and keratocytes, but the cell type-specific mechanisms underlying migration of lineage- or disease-specific cells, such as neural and glial progenitor cells, remain an active field for investigation. The migrating neural and glial progenitor cells contribute ...
    Single-cell Motility Analysis of Tethered Human Spermatozoa
    Authors:  William M. Skinner, Nadja Mannowetz, Polina V. Lishko and Nadia R. Roan, date: 03/05/2019, view: 2745, Q&A: 0
    [Abstract] Vigorous sperm flagellar motility is essential for fertilization, and so the quantitative measurement of motility is a useful tool to assess the intrinsic fertility potential of sperm cells and explore how various factors can alter sperm’s ability to reach the egg and penetrate its protective layers. Human sperm beat their flagella many times each ...
    Human Endothelial Cell Spheroid-based Sprouting Angiogenesis Assay in Collagen
    Authors:  Fabian Tetzlaff and Andreas Fischer, date: 09/05/2018, view: 7724, Q&A: 0
    [Abstract] Angiogenesis, the formation of new blood vessels from pre-existing ones plays an important role during organ development, regeneration and tumor progression. The spheroid-based sprouting assay is a well-established and robust method to study the influence of genetic alterations or pharmacological compounds on capillary-like tube formation of ...
    Fluorescent Labeling of Rat-tail Collagen for 3D Fluorescence Imaging
    Author:  Andrew D. Doyle, date: 07/05/2018, view: 4324, Q&A: 0
    [Abstract] Rat tail collagen solutions have been used as polymerizable in vitro three-dimensional (3D) extracellular matrix (ECM) gels for single and collective cell migration assays as well as spheroid formation. These 3D hydrogels are a relatively inexpensive, simple to use model system that can mimic the in vivo physical characteristics ...
