Effects of Oxidative Stress on Mesenchymal Stem Cell Biology
Mesenchymal stromal/stem cells (MSCs) are multipotent stem cells present in most fetal and adult tissues. Ex vivo culture-expanded MSCs are being investigated for tissue repair and immune modulation, but their full clinical potential is far from realization. Here we review the role of oxidative stress in MSC biology, as their longevity and functions are affected by oxidative stress. In general,...
متن کاملCell Survival Effects of Autophagy Regulation on Umbilical Cord-Derived Mesenchymal Stem Cells Following Exposure to Oxidative Stress
Background: Due to oxidative stress, hypoxia, and serum deprivation, a large percentage of mesenchymal stem cells (MSCs) die in the early stages of transplantation. The present study aimed to address whether induction or inhibition of autophagy would affect the viability of MSCs after exposure to oxidative stress.Methods: MSCs were isolated from umbilical cord tissue using the Ficoll grad...
متن کاملGene Delivery to Mesenchymal Stem Cells
There is increasing trend in using recombinant stem cells as novel therapeutic candidates in different diseases. These studies encompass different applications from targeted homing of Mesenchymal Stromal (stem) Cells (MSC), to arming them with different cytokines. Resistance to transfection or transduction methods had urged researchers to look for better gene delivery alternates and optimizing ...
متن کاملVisible light photoinitiation of mesenchymal stem cell-laden bioresponsive hydrogels.
Biological activity can be added to synthetic scaffolds by incorporating functional peptide sequences that provide enzyme-mediated degradation sites, facilitate cellular adhesion or stimulate signaling pathways. Poly(ethylene glycol) diacrylate is a popular synthetic base for tissue engineering scaffolds because it creates a hydrophilic environment that can be chemically manipulated to add this...
متن کاملPara-nonylphenol Toxicity Induces Oxidative Stress and Arrests the Cell Cycle in Mesenchymal Stem Cells of Bone Marrow
Background: The mechanism of para-nonylphenol (PNP) reducing the proliferation and differentiation of bone marrow mesenchymal stem cells (MSCs) is not known. The present study was designed to investigate the mechanism. Methods: MSCs were extracted under sterile condition from Wistar rat and cultured in DMEM, containing 15 % FBS and penicillin/streptomycin until the 3rd passage, then cells we...
