    Studysummary This review highlights how diabetes affects stem and progenitor cells through altered signaling and homeostasis, impacting tissue function and complicating diabetic therapy efforts; new clinical results are not presented. Our plain-language summary of this paper — not a Tressless recommendation.
    The study concluded that progenitor cell dysfunctions significantly contributed to various diabetic complications by impairing tissue repair and regeneration. Diabetes-induced hyperglycemia disrupted progenitor cell functions, leading to poor wound healing, cardiovascular issues, and reduced neovascularization. Despite glycemic control, some dysfunctions persisted due to hyperglycemic memory and lasting epigenetic changes. The research emphasized the potential of targeting progenitor cell function and preconditioning stem cells with agents like deferoxamine (DFO) to improve outcomes, although challenges remained in replicating the diabetic environment in vitro and addressing genetic changes.
