    Maintenance of Schmidtea mediterranea in the Laboratory
    Authors:  Nídia de Sousa and Teresa Adell, date: 10/05/2018, view: 76, Q&A: 0
    In the last years, planarians have emerged as a unique model animal for studying regeneration and stem cells biology. Although their remarkable regenerative abilities are known for a long time, only recently the molecular tools to understand the ...
    Isolation of Chromatin-bound Proteins from Subcellular Fractions for Biochemical Analysis
    Author:  Sébastien Gillotin, date: 10/05/2018, view: 93, Q&A: 0
    Shuttling of proteins between different cellular compartments controls their proteostasis and can contribute in some cases to regulate their activity. Biochemical analysis of chromatin-bound proteins, such as transcription factors, is often ...
    Maintenance of Schmidtea mediterranea in the Laboratory

    [Abstract] In the last years, planarians have emerged as a unique model animal for studying regeneration and stem cells biology. Although their remarkable regenerative abilities are known for a long time, only recently the molecular tools to understand the biology of planarian stem cells and the fundamentals of their regenerative process have been ...
    Isolation of Chromatin-bound Proteins from Subcellular Fractions for Biochemical Analysis
    Author:  Sébastien Gillotin, date: 10/05/2018, view: 93, Q&A: 0
    [Abstract] Shuttling of proteins between different cellular compartments controls their proteostasis and can contribute in some cases to regulate their activity. Biochemical analysis of chromatin-bound proteins, such as transcription factors, is often difficult because of their low yield and due to the interference from nucleic acids. This protocol describes ...
    Qualitative in vivo Bioluminescence Imaging
    Authors:  Devbarna Sinha, Zalitha Pieterse and Pritinder Kaur, date: 09/20/2018, view: 350, Q&A: 0
    [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 ...
    Microarray, IPA and GSEA Analysis in Mice Models
    [Abstract] This protocol details a method to analyze two tissue samples at the transcriptomic level using microarray analysis, ingenuity pathway analysis (IPA) and gene set enrichment analysis (GSEA). Methods such as these provide insight into the mechanisms underlying biological differences across two samples and thus can be applied to interrogate a variety ...
    Investigating Neural Stem Cell and Glioma Stem Cell Self-renewal Potential Using Extreme Limiting Dilution Analysis (ELDA)
    Authors:  Hong PT Nguyen, Paul M Daniel, Gulay Filiz and Theo Mantamadiotis, date: 09/05/2018, view: 283, Q&A: 0
    [Abstract] Glioma stem cells (GSC) grown as neurospheres exhibit similar characteristics to neural stem cells (NSC) grown as neurospheres, including the ability to self-renew and differentiate. GSCs are thought to play a role in cancer initiation and progression. Self-renewal potential of GSCs is thought to reflect many characteristics associated with ...
    Generation of Human Mesenchymal Stem Cell 3D Spheroids Using Low-binding Plates
    [Abstract] The 3D culture of human mesenchymal stem cells (hMSCs) represents a more physiological environment than classical 2D culture and has been used to enhance the MSC secretome or extend cell survival after transplantation. Here we describe a simple and affordable method to generate 3D spheroids of hMSCs by seeding them at high density in a low-binding ...
    Small Molecule-Based Retinal Differentiation of Human Embryonic Stem Cells and Induced Pluripotent Stem Cells
    Authors:  Jie Zhu and Deepak A. Lamba, date: 06/20/2018, view: 979, Q&A: 0
    [Abstract] Retinal degeneration leads to loss of light-sensing photoreceptors eventually resulting in vision impairment and impose a heavy burden on both patients and the society. Currently available treatment options are very limited and mainly palliative. Ever since the discovery of human pluripotent stem cell technologies, cell replacement therapy has ...
    Expansion of Airway Basal Cells and Generation of Polarized Epithelium
    Authors:  Hannah Levardon, Lael M. Yonker, Bryan P. Hurley and Hongmei Mou, date: 06/05/2018, view: 1221, Q&A: 1
    [Abstract] Airway basal stem cells are the progenitor cells within the airway that exhibit the capacity to self-renew and give rise to multiple types of differentiated airway epithelial cells. This stem cell-derived epithelium displays organized architecture with functional attributes of the airway mucosa. A protocol has been developed to culture and expand ...
    High Dimensional Functionomic Analysis of Human Hematopoietic Stem and Progenitor Cells at a Single Cell Level
    Authors:  Thomas Luh, Kimberly Lucero, Wenji Ma, Jaeyop Lee, Yu Jerry Zhou, Yufeng Shen and Kang Liu, date: 05/20/2018, view: 1101, Q&A: 0
    [Abstract] The ability to conduct investigation of cellular transcription, signaling, and function at the single-cell level has opened opportunities to examine heterogeneous populations at unprecedented resolutions. Although methods have been developed to evaluate high-dimensional transcriptomic and proteomic data (relating to cellular mRNA and protein), ...
    Osteoblast Sorting and Intracellular Staining of CXCL12
    Authors:  Weihuan Wang, Gurnoor Majhail, Cui Lui and Lan Zhou, date: 05/20/2018, view: 946, Q&A: 0
    [Abstract] Osteoblasts are bone marrow endosteum-lining niche cells playing important roles in the regulation of hematopoietic stem cells by secreting factors and cell adhesion molecules. Characterization of primary osteoblasts has been achieved through culture of outgrowth of collagenase treated bone. Immunophenotyping and flow-based analysis of long bone ...
