IntroductionRegenerative treatment using stem cells represents a potentially effective therapy for cerebellar ataxia (CA). We compared the therapeutic potential of adipose tissue stem cells (ASCs) and bone marrow mesenchymal stem cells (BM-MSCs) in a rodent monosodium glutamate (MSG)-induced CA cell (BM-MSC) model.Material and methodsFemale Wistar rats (n = 40) were equally divided into a saline-treated control group and 3 MSG-induced CA groups randomly treated with either saline, or 1 × 106 ASCs or BM-MSCs. We assessed the following: 1) cerebellar motor functions in vivo (by Rotarod test, open-field test, and Quantitative gait analysis); 2) cerebellar histological architecture; and 3) cerebellar immunohistochemical examination of the Bax/Bcl-2 ratio as in indicator of apoptosis, and the levels of vascular endothelial growth factor (VEGF) and insulin-like growth factor-1 (IGF-1) as neuroprotective factors.ResultsTreatment with either of the MSCs improved MSG-induced poor motor performance, restored the disrupted Purkinje cell layer, decreased neuronal apoptosis and enhanced cerebellar VEGF and IGF-1 levels observed in CA rats. Adipose tissue stem cells showed superiority over BM-MSCs in the improvement of some motor performance parameters and cerebellar VEGF and IGF-1 levels.ConclusionsIn conclusion, both stem cell types induced structural, physiological, and biochemical improvement, with ASCs being best for treatment of CA.

AbstractNeurodegenerative diseases (NDs), such as Alzheimer’s disease (AD), are driven by neuroinflammation triggered by activated microglial cells; hence, the phenotypic regulation of these cells is an appealing target for intervention. Human adipose tissue-derived mesenchymal stem cells (hAD-MSCs) may be a potential therapeutic candidate to treat NDs given their immunomodulatory properties. Evidence suggests that the mechanism of action of hAD-MSCs is through their secretome, which includes secreted factors such as cytokines, chemokines, or growth factors as well as extracellular vesicles (EVs). Recently, EVs have emerged as important mediators in cell communication given, they can transfer proteins, lipids, and RNA species (i.e., miRNA, mRNA, and tRNAs) to modulate recipient cells. However, the therapeutic potential of hAD-MSCs and their secreted EVs has not been fully elucidated with respect to human microglia. In this study, we determined the therapeutic potential of different hAD-MSCs doses (200,000, 100,000, and 50,000 cells) or their secreted EVs (50, 20, or 10 µg/ml), on human microglial cells (HMC3) that were activated by lipopolysaccharides (LPS). Upregulation of inducible nitric oxide synthase (iNOS), an activation marker of HMC3 cells, was prevented when they were cocultured with hAD-MSCs and EVs. Moreover, hAD-MSCs inhibited the secretion of proinflammatory factors, such as IL-6, IL-8, and MCP-1, while their secreted EVs promoted the expression of anti-inflammatory mediators such as IL-10 or TIMP-1 in activated microglia. The present data therefore support a role for hAD-MSCs and their secreted EVs, as potential therapeutic candidates for the treatment of NDs.

The long-held belief about adipose tissue was that it was relatively inert in terms of biological activity. It was believed that its primary role was energy storage; however, that was shattered with the discovery of adipokines. Scientists interested in regenerative medicine then reported that adipose tissue is rich in adult stromal/stem cells. Following these initial reports, adipose stem cells (ASCs) rapidly garnered interest for use as potential cellular therapies. The primary advantages of ASCs compared to other mesenchymal stem cells (MSCs) include the abundance of the tissue source for isolation, the ease of methodologies for tissue collection and cell isolation, and their therapeutic potential. Studies conducted both in vitro and in vivo have demonstrated that ASCs are multipotent, possessing the ability to differentiate into cells of mesodermal origins, including adipocytes, chondrocytes, osteoblast and others. Moreover, ASCs produce a broad array of cytokines, growth factors, nucleic acids (miRNAs), and other macromolecules into the surrounding milieu by secretion or in the context of microvesicles. The secretome of ASCs has been shown to alter tissue biology, stimulate tissue-resident stem cells, change immune cell activity, and mediate therapeutic outcomes. The quality of ASCs is subject to donor-to-donor variation driven by age, body mass index, disease status and possibly gender and ethnicity. This review discusses adipose stromal/stem cell action mechanisms and their potential utility as cellular therapeutics.
