Pretreatment with Lycopene Attenuates Oxidative Stress-Induced Apoptosis in Human Mesenchymal Stem Cells
Human mesenchymal stem cells (MSCs) have been used in cell-based therapy to promote revascularization after peripheral or myocardial ischemia. High levels of reactive oxygen species (ROS) are involved in the senescence and apoptosis of MSCs, causing defective neovascularization. Here, we examined the effect of the natural antioxidant lycopene on oxidative stress-induced apoptosis in MSCs. Altho...
متن کاملHypoxic preconditioning induces the expression of prosurvival and proangiogenic markers in mesenchymal stem cells.
Stem cells transplanted to the ischemic myocardium usually encounter massive cell death within a few days of therapy. Hypoxic preconditioning (HPC) is currently employed as a strategy to prepare stem cells for increased survival and engraftment in the heart. However, HPC of stem cells has provided varying results, supposedly due to the differences in the oxygen concentration, duration of exposu...
متن کاملHypoxic Preconditioning Promotes the Bioactivities of Mesenchymal Stem Cells via the HIF-1α-GRP78-Akt Axis
Mesenchymal stem cells (MSC) are ideal materials for stem cell-based therapy. As MSCs reside in hypoxic microenvironments (low oxygen tension of 1% to 7%), several studies have focused on the beneficial effects of hypoxic preconditioning on MSC survival; however, the mechanisms underlying such effects remain unclear. This study aimed to uncover the potential mechanism involving 78-kDa glucose-r...
متن کاملNormobaric hyperoxia preconditioning attenuates streptozotocin - induced impairments in spatial learning
Introduction: A large body of evidence points to oxidative stress as prime candidate mediating the behavioral impairments and memory deficits in Alzheimer's disease (AD). It has been demonstrated that hyperoxia preconditioning activates complex endogenous neuroprotective mechanisms including an increase in capacity of antioxidant defence mechanisms. The aim of this study was to investigate the ...
متن کاملHypoxia Preconditioning Promotes Survival And Clonogenic Capacity Of Human Umbilical Cord Blood Mesenchymal Stem Cells
Background: In recent decade, human umbilical cord blood derived mesenchymal stem cells (hUCB-MSCs) provide enormous potential for appropriate cell therapy, but they have limited growth potential and cease to proliferate due to cellular senescence, so providing a strategy for increasing the stem cell survival is necessary. Methods: In this investigation, MSCs characterized by flow cytome...
