    Imaging of Human Cancer Cells in 3D Collagen Matrices
    Authors:  Karin Pfisterer, Brooke Lumicisi and Maddy Parsons, date: 01/20/2021, view: 159, Q&A: 0

    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: 2414, 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, ...
    In vivo Tumor Growth and Spontaneous Metastasis Assays Using A549 Lung Cancer Cells
    [Abstract] Metastasis accounts for the majority of cancer related deaths. The genetically engineered mouse (GEM) models and cell line-based subcutaneous and orthotopic mouse xenografts have been developed to study the metastatic process. By using lung cancer cell line A549 as an example, we present a modified protocol to establish the cell line-based ...
    Bone-in-culture Array to Model Bone Metastasis in ex vivo Condition
    Authors:  Hai Wang and Xiang H.-F. Zhang, date: 01/20/2020, view: 1639, Q&A: 0
    [Abstract] Bone is the most frequently affected organ by metastases of breast cancer and prostate cancer. Our knowledge on bone metastasis is extremely limited due to the lack of potent and efficient experimental models. We developed the “Bone-In-Culture Array (BICA)” platform to model the bone colonization of cancer cells in ex vivo cultures. The ...
    Analysis of Random Migration of Cancer Cells in 3D
    Authors:  Sai P. Visweshwaran and Alexis Gautreau, date: 01/05/2020, view: 2289, 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 ...
    Labeling and Isolation of Fluorouracil Tagged RNA by Cytosine Deaminase Expression
    Authors:  Harihar Basnet and Joan Massague, date: 11/20/2019, view: 1900, Q&A: 0
    [Abstract] Tissues are comprised of different cell types whose interactions elicit distinct gene expression patterns that regulate tissue formation, regeneration, homeostasis and repair. Analysis of these gene expression patterns require methods that can capture as closely as possible the transcriptomes of cells of interest in their tissue microenvironment. ...
    F-actin Bundle Sedimentation Assay
    Authors:  Shan-Shan Lin, Mei-Chun Chuang and Ya-Wen Liu, date: 11/05/2019, view: 2353, Q&A: 0
    [Abstract] Understanding the molecular mechanism governing the higher-order regulation of actin dynamics requires chemically-defined and quantitative assays. Recently, the membrane remodeling large GTPase, dynamin, has been identified as a new actin cross-linking molecule. Dynamin regulates actin cytoskeleton through binding to, self-assembling around, and ...
    Calvarial Bone Implantation and in vivo Imaging of Tumor Cells in Mice
    Authors:  Kyoko Hashimoto, Shingo Sato, Hiroki Ochi, Shu Takeda and Mitsuru Futakuchi, date: 02/05/2019, view: 3862, Q&A: 0
    [Abstract] Bone is one of common metastasis sites for many types of cancer. In bone metastatic microenvironment, tumor-bone interactions play a significant role in the regulation of osteolytic or osteoblastic bone metastasis. In order to investigate the direct interaction between tumor cells and bone tissue, it is essential to generate appropriate animal ...
    Qualitative in vivo Bioluminescence Imaging
    Authors:  Devbarna Sinha, Zalitha Pieterse and Pritinder Kaur, date: 09/20/2018, view: 5344, Q&A: 1
    [Abstract] Bioluminescence imaging (BLI) technology is an advanced method of carrying out molecular imaging on live laboratory animals in vivo. This powerful technique is widely-used in studying a variety of biological processes, and it has been an ideal tool in exploring tumor growth and metastatic spread in real-time. This technique ensures the ...
    Zebrafish Embryo Xenograft and Metastasis Assay
    Authors:  Ilkka Paatero, Sanni Alve, Silvia Gramolelli, Johanna Ivaska and Päivi M. Ojala, date: 09/20/2018, view: 6881, Q&A: 1
    [Abstract] Xenograft models, and in particular the mouse xenograft model, where human cancer cells are transplanted into immunocompromised mice, have been used extensively in cancer studies. Although these models have contributed enormously to our understanding of cancer biology, the zebrafish xenograft model offers several advantages over the mouse model. ...
