    Measurements of Root Colonized Bacteria Species
    Authors:  Vílchez Juan Ignacio, Yu Yang, Dian Yi and Huiming Zhang, date: 04/05/2021, view: 204, Q&A: 0
    [Abstract]

    Root-associated bacteria are able to influence plant fitness and vigor. A key step in understanding the belowground plant-bacteria interactions is to quantify root colonization by the bacteria of interest. Probably, genetic engineering with fluorescence markers is the most powerful way to monitor bacterial strains in plant. However, this could

    Generation of Mouse Primary Hypothalamic Neuronal Cultures for Circadian Bioluminescence Assays
    Authors:  Cosima X. Schmidt, Anthony H. Tsang and Henrik Oster, date: 03/05/2021, view: 446, Q&A: 0
    [Abstract]

    An endogenous circadian clock system enables organisms to adapt to time-of-day dependent environmental changes. In consequence, most physiological processes exhibit daily rhythms of, e.g., energy metabolism, immune function, sleep, or hormone production. Hypothalamic circadian clocks have been identified to play a particular role in coordinating

    Strategy of Isolating ‘Primed’ Tumor Initiating Cells Based on Mitochondrial Transmembrane Potential
    Authors:  Brian Spurlock, Vidya Sagar Hanumanthu and Kasturi Mitra, date: 03/05/2021, view: 1184, Q&A: 0
    [Abstract]

    Various stem cells have been found to be dependent on mitochondrial energetics. The role of mitochondria in regulating the self-renewal of normal stem cells and stem-like tumor initiating cells (TICs) is increasingly being appreciated. We proposed that TIC populations have a sub population of cells that are “primed” by mitochondria for

    Isolation of Murine Primary Aortic Smooth Muscle Cells
    Authors:  Max Ole Hubert, Juan Rodriguez-Vita, Lena Wiedmann and Andreas Fischer, date: 02/05/2021, view: 472, Q&A: 0
    [Abstract]

    Vascular smooth muscle cells (VSMCs) have been cultured for decades to study the role of these cells in cardiovascular disorders. The most common source of VSMCs is the rat aorta. Here we show the adaptation of this method to isolate and culture mouse aortic VSMCs. The advantage of this method is that there are many more transgenic mouse lines

    Rapid and Simplified Induction of Neural Stem/Progenitor Cells (NSCs/NPCs) and Neurons from Human Induced Pluripotent Stem Cells (hiPSCs)
    Authors:  Ryutaro Kajihara, Tadahiro Numakawa and Takumi Era, date: 02/05/2021, view: 454, Q&A: 0
    [Abstract]

    Human induced pluripotent stem cells (iPSCs) and their progeny displaying tissue-specific characteristics have paved the way for regenerative medicine and research in various fields such as the elucidation of the pathological mechanism of diseases and the discovery of drug candidates. iPSC-derived neurons are particularly valuable as it is

    Stable Transformation of Arabidopsis thaliana Cell Suspension Cultures: A Case Study for the Overexpression of The COI1 Receptor
    [Abstract] Cell suspension cultures have been studied for decades to produce natural molecules. However, the difficulty in generating stably transformed cell lines has limited their use to produce high value chemicals reproducibly and in elevated quantities.

    In this protocol, a method to stably transform and maintain Arabidopsis cell ...
    Differentiation of Human Induced Pluripotent Stem Cells (hiPSCs) into Osteoclasts
    Author:  I-Ping Chen, date: 12/20/2020, view: 802, Q&A: 0
    [Abstract]

    Defects in bone resorption by osteoclasts result in numerous rare genetic bone disorders as well as in some common diseases such as osteoporosis or osteopetrosis. The use of hiPSC-differentiated osteoclasts opens new avenues in this research field by providing an unlimited cell source and overcoming obstacles such as unavailability of human

    Isolation of Extracellular Vesicles Derived from Mesenchymal Stromal Cells by Ultracentrifugation
    [Abstract] Extracellular vesicles (EVs) are a heterogeneous group of membranous vesicles that differ on their biogenesis and release pathways, such as exosomes, microvesicles and apoptotic bodies. They are involved in cell-to-cell communication delivering signal molecules (proteins, nucleic acids, lipids, etc.) that can regulate different ...
    Protocol for Isolation, Stimulation and Functional Profiling of Primary and iPSC-derived Human NK Cells
    [Abstract]

    Natural killer (NK) cells are innate immune cells, characterized by their cytotoxic capacity, and chemokine and cytokine secretion upon activation. Human NK cells are identified by CD56 expression. Circulating NK cells can be further subdivided into the CD56bright (~10%) and CD56dim NK cell subsets (~90%). NK cell-like cells can also be derived

    Dissecting the Rat Mammary Gland: Isolation, Characterization, and Culture of Purified Mammary Epithelial Cells and Fibroblasts
    [Abstract]

    With the advent of CRISPR-Cas and the ability to easily modify the genome of diverse organisms, rat models are being increasingly developed to interrogate the genetic events underlying mammary development and tumorigenesis. Protocols for the isolation and characterization of mammary epithelial cell subpopulations have been thoroughly developed for
