However, the clinical application of ADSC-based therapies is substantially limited by the harsh microenvironment of acute wounds, characterized by hypoxia, nutrient deprivation, and oxidative stress, which leads to massive apoptotic cell death post-transplantation. Preconditioning strategies to enhance cellular resilience have thus gained considerable interest. Recent insights from cancer biology highlight the crucial role of metabolic reprogramming, orchestrated by hypoxia-inducible factor-1α (HIF-1α), in promoting survival under stress. Our previous work demonstrated that preconditioning with α-ketoglutarate (α-KG) enhances ADSC survival and accelerates wound healing, purportedly through HIF-1α upregulation. Nevertheless, the precise metabolic mechanisms by which α-KG preconditioning confers cytoprotection remain incompletely elucidated.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Aim: &lt;/strong&gt;To investigate the mechanistic role of HIF-1α in mediating the enhanced survival and regenerative capacity of α-KG-preconditioned ADSCs in an acid burn wound model. Specifically, we sought to determine whether HIF-1α activation drives complementary adaptations in glutamine and glycogen metabolism to maintain redox and energy homeostasis, respectively, under the multifactorial stress conditions of a wound.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Methods: &lt;/strong&gt;Human ADSCs were isolated from lipoaspirates and preconditioned with dimethyl-α-KG. &lt;i&gt;In vitro&lt;/i&gt;, cells were subjected to single or combined stressors (hypoxia, glucose deprivation, H&lt;sub&gt;2&lt;/sub&gt;O&lt;sub&gt;2&lt;/sub&gt;-induced oxidative stress). Genetic modulation was performed using lentiviral shRNAs targeting HIF-1α, GLS1, and PYGL, or an overexpression vector for GLS1. Metabolic profiling included assessments of glycolytic flux, glucose oxidation, fatty acid β-oxidation, oxygen consumption, and glycogen content. Redox status was evaluated &lt;i&gt;via&lt;/i&gt; glutathione (GSH) (GSH/GSH disulfide) ratios and reactive oxygen species (ROS) levels. &lt;i&gt;In vivo&lt;/i&gt;, a murine acid burn wound model was established, and pre-labeled ADSCs were implanted. Cell survival was tracked &lt;i&gt;via&lt;/i&gt; flow cytometry (Annexin V-PI) and terminal deoxynucleotidyl transferase dUTP nick end labeling staining. Wound healing was assessed histologically.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;α-KG preconditioning significantly enhanced the survival of ADSCs both &lt;i&gt;in vitro&lt;/i&gt; under stress and &lt;i&gt;in vivo&lt;/i&gt; in burn wounds. This was concomitant with HIF-1α stabilization. Mechanistically, HIF-1α orchestrated a dual metabolic adaptation: (1) It promoted glutaminolysis &lt;i&gt;via&lt;/i&gt; GLS1, increasing glutamate and GSH synthesis, which enhanced antioxidant capacity and reduced ROS levels; and (2) It simultaneously stimulated glycogen storage (Gys1 upregulation) and mobilizat","PeriodicalId":23775,"journal":{"name":"World journal of stem cells","volume":"18 2","pages":"113694"},"PeriodicalIF":4.9,"publicationDate":"2026-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12968792/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147435896","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
