Abstract:C ritical limb ischemia (CLI) and ischemic stroke are common manifestations of atherosclerosis and vascular occlusion of peripheral and cerebral arteries, respectively, leading to cell death and tissue necrosis. CLI is characterized by pain at rest, nonhealing wounds, and gangrene, progressing to loss of limb and high rates of mortality. The leading risk factors of CLI are diabetes mellitus and age. Currently, there are no effective pharmacological interventions to treat CLI. Revascularization through endovasc… Show more
“…3 In an experimental model of CLI, they showed that treatment with hNSCs promoted neovascularization of the ischemic limb in immunodeficient animals as well as in immunocompetent CD-1 and streptozotocin-induced diabetic mice. 2 Comparison of the hNSCs with human mesenchymal stem cells indicated a similar improvement in blood flow. Histological studies in ischemic leg of immunocompetent mice during the first 7 days after treatment revealed short-term hNSC survival, transient elevation of early host muscle inflammatory and angiogenic responses, and acceleration of myogenesis.…”

“…Histological studies in ischemic leg of immunocompetent mice during the first 7 days after treatment revealed short-term hNSC survival, transient elevation of early host muscle inflammatory and angiogenic responses, and acceleration of myogenesis. 2 However, grafted hNSCs mainly acquired an inflammatory phenotype, and the early transient increases in inflammatory cytokines, chemokines, and growth factor expression were observed in hNSC-treated ischemic muscle although classic inflammatory cell responses were not affected. Hence, the inflammatory phenotype and function of hNSCs are most likely induced by the implantation into the ischemic environment of immunocompetent mice.…”

“…Interestingly, in this study, the immunogenic potential of hNSCs seemed to be low, and there was comparable efficacy in both nude and wild-type CD-1 mice, both at short-term and long-term, without any evidence of rejection of these cells from the recipient animals. 2 This could be explained by a previous study that showed that CTX0E03 hNSCs do not express major histocompatibility complex II and do not promote a sustained host cellular response. 3 The other well-known prototype of immunoprivileged cells suitable for allogeneic applications is human mesenchymal stem cells.…”

“…61 CTX0E03, a line of human neural stem cells thought to promote angiogenesis and neurogenesis in stroke, also showed progress in a hind limb ischemia model. 62 Though mesenchymal stem cells have a therapeutic benefit, recent studies suggest that they may also play a role in the pathology of aortic valve disease. 63 One potential mechanism for this is regulation of endothelial-to-mesenchymal transitions during stem cell differentiation.…”

“…64 Interestingly, a clinical-grade human neural stem cell line promotes angiogenesis and neurogenesis in a preclinical model of stroke and is now showed the therapeutic activity of intramuscular implantation in murine models of hindlimb ischemia. 65 In addition, mouse iPS cell-derived Flk-1 + or Flk-1 − cells were intravenously injected into the mice after vascular injury that significantly attenuated neointimal hyperplasia when compared with controls. 62 Administration of iPS cellderived Flk-1 + cells significantly enhanced reendothelialization when compared with that of the Flk-1 − cell control group, 62 indicating a potentially useful therapeutic means for vascular dysfunction and prevention of restenosis after angioplasty.…”
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
