    Image-based Quantification of Macropinocytosis Using Dextran Uptake into Cultured Cells
    Authors:  Anh H. Le and Laura M. Machesky, date: 04/05/2022, view: 717, Q&A: 0
    [Abstract]

    Macropinocytosis is an evolutionarily conserved process, which is characterized by the formation of membrane ruffles and the uptake of extracellular fluid. We recently demonstrated a role for CYFIP-related Rac1 Interactor (CYRI) proteins in macropinocytosis. High-molecular weight dextran (70kDa or higher) has generally been used as a marker for

    Studying Chemotactic Migration in Dunn Chamber: An Example Applied to Adherent Cancer Cells
    Authors:  Khedidja Benseddik and Kossay Zaoui, date: 02/05/2022, view: 1072, Q&A: 0
    [Abstract]

    Cell migration is a vital process in the development of multicellular organisms. When deregulated, it is involved in many diseases such as inflammation and cancer metastisation. Some cancer cells could be stimulated using chemoattractant molecules, such as growth factor Heregulin β1. They respond to the attractant or repellent gradients

    Imaging of Human Cancer Cells in 3D Collagen Matrices
    Authors:  Karin Pfisterer, Brooke Lumicisi and Maddy Parsons, date: 01/20/2021, view: 3662, Q&A: 0
    [Abstract]

    Research on cell migration and interactions with the extracellular matrix (ECM) was mostly focused on 2D surfaces in the past. Many recent studies have highlighted differences in migratory behaviour of cells on 2D surfaces compared to complex cell migration modes in 3D environments. When embedded in 3D matrices, cells constantly sense the

    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: 4676, 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: 4276, Q&A: 1
    [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 ...
    In vitro Tumor Cell Migration Assay Using ThinCertsTM (Transwells)
    Author:  Marc A. Schneider, date: 06/05/2016, view: 16232, Q&A: 0
    [Abstract] The high migration rate of tumor cells often results in poor prognosis for the survival of the patients. Here, we describe a protocol to measure the migration of cells using a quantitative assay. The relative tumor cell migration was measured using ThinCertsTM cell culture inserts and a lactate dehydrogenase (LDH) assay to quantify the ...
    PhagoKinetic Track Assay: Imaging and Analysis of Single Cell Migration
    [Abstract] Cell migration is a highly complex and dynamic biological process, essential in several physiological phenomena and pathologies including cancer dissemination and metastasis formation. Thus understanding single cell migration is highly relevant and requires a suitable image-based assay. Depending on the speed of the moving cells, one may require ...
    Scratch Wound Healing Assay
    Author:  Yanling Chen, date: 03/05/2012, view: 117972, Q&A: 6
    [Abstract] The scratch wound healing assay has been widely adapted and modified to study the effects of a variety of experimental conditions, for instance, gene knockdown or chemical exposure, on mammalian cell migration and proliferation. In a typical scratch wound healing assay, a “wound gap” in a cell monolayer is created by scratching, and the “healing” ...
