    TZA, a Sensitive Reporter Cell-based Assay to Accurately and Rapidly Quantify Inducible, Replication-competent Latent HIV-1 from Resting CD4+ T Cells
    Authors:  Anwesha Sanyal, Vatsala S. Rangachar and Phalguni Gupta, date: 05/20/2019, view: 215, Q&A: 0
    [Abstract] The latent HIV-1 viral reservoir in resting CD4+ (rCD4+) T cells represents a major barrier to an HIV-1 cure. There is an ongoing effort to identify therapeutic approaches that will eliminate or reduce the size of this reservoir. However, clinical investigators lack an assay to determine whether or not a decrease in the ...
    3D Co-culture System of Mouse Prostatic Wild-type Fibroblasts with Human Prostate Cancer Epithelial Cells
    Authors:  Veronica R. Placencio-Hickok, Manabu Kato and Neil A. Bhowmick, date: 05/05/2019, view: 427, Q&A: 0
    [Abstract] Heterogeneous prostatic carcinoma-associated fibroblasts (CAF) contribute to tumor progression. This was established using transgenic mouse models. Paracrine interactions between fibroblasts and epithelial cells were further interrogated using isolated 2D cell culture systems, but 3D culture systems currently being developed can better mimic ...
    Primary Embryonic Rat Cortical Neuronal Culture and Chronic Rotenone Treatment in Microfluidic Culture Devices
    Authors:  Victor S. Van Laar, Beth Arnold and Sarah B Berman, date: 03/20/2019, view: 575, Q&A: 0
    [Abstract] In the study of neurodegenerative diseases, it is imperative to study the cellular and molecular changes associated with pathogenesis in the relevant cell type, central nervous system neurons. The unique compartmentalized morphology and bioenergetic needs of primary neurons present complications for their study in culture. Recent microculture ...
    Differentiation of Human Induced Pluripotent Stem Cells (iPSCs) into an Effective Model of Forebrain Neural Progenitor Cells and Mature Neurons
    [Abstract] Induced Pluripotent Stem Cells (iPSCs) are pluripotent stem cells that can be generated from somatic cells, and provide a way to model the development of neural tissues in vitro. One particularly interesting application of iPSCs is the development of neurons analogous to those found in the human forebrain. Forebrain neurons play a central ...
    Induced Germinal Center B Cell Culture System
    Authors:  Kei Haniuda and Daisuke Kitamura, date: 02/20/2019, view: 1112, Q&A: 0
    [Abstract] The germinal center (GC) is the site where B cells undergo clonal expansion, affinity-based selection, and differentiation into memory B cells or plasma cells. It has been difficult to elucidate regulatory mechanisms for the dynamic GC B cell maturation and differentiation, partly because experimental manipulation of GC B cells in vivo ...
    Top Starch Plating Method for the Efficient Cultivation of Unicellular Red Alga Cyanidioschyzon merolae
    Authors:  Tokiaki Takemura, Yuki Kobayashi, Sousuke Imamura and Kan Tanaka, date: 02/20/2019, view: 630, Q&A: 0
    [Abstract] The unicellular red alga Cyanidioschyzon merolae has been used as a model photosynthetic eukaryote for various basic and applied studies, and several of these molecular genetics techniques have been reported. However, there are still improvements to be made concerning the plating method. The conventional plating method often generates ...
    Isolation of Multipotent Mesenchymal Stem Cells from Human Extraocular Muscle Tissue
    Authors:  Amit Sharma, Darilang Mawrie, Damarais Magdalene and Bithiah Grace Jaganathan, date: 02/20/2019, view: 678, Q&A: 0
    [Abstract] Mesenchymal stem cells (MSCs) have attracted significant attention as potential therapeutic cells to treat various diseases ranging from tissue injuries, graft versus host disease, degenerative diseases and cancer. Since the initial discovery of MSCs in the bone marrow cells, MSCs have been successfully isolated from various adult and neo-natal ...
    Induction and Analysis of Anti-CD40-induced Colitis in Mice
    Authors:  Barbara Joyce-Shaikh, Daniel J. Cua and David Bauché, date: 02/05/2019, view: 1097, Q&A: 0
    [Abstract] Colon inflammation or colitis affects more than 1 million people worldwide. Several pre-clinical models, including chemical-induced (i.e., DSS, TNBS) or pathogen-induced (i.e., Citrobacter rodentium) have been used to study mechanisms involved in the development and regulation of colitis. Anti-CD40 induced colitis model ...
    Assessment of Humoral Alloimmunity in Mixed Lymphocyte Reaction
    Authors:  Georgios Pissas and Theodoros Eleftheriadis, date: 01/20/2019, view: 1046, Q&A: 0
    [Abstract] Humoral alloimmunity remains a significant and unresolved problem that constrains allograft survival. Thus, there is a need for the development of an easy, preferably non-radioactive, and inexpensive protocol for assessing the effect of various drug treatments on humoral alloimmunity. In order to satisfy this demand, we developed such a protocol ...
    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 ...
