In recent years, cellular therapy (CT) products such as mesenchymal stem cells (MSC), platelet-rich plasma (PRP), and stromal vascular fraction (SVF) have been widely used. A combined cellular therapy (CCT) has not yet been tested as a triple combination, although its use alone and in dual combinations has been investigated. Probiotics (PB) accelerate healing by altering the intestinal microbiota. This study aims to examine the role of PB in enhancing the effects of CCT on diabetic wound healing. METHODS: A 1×1 cm2 full-thickness cutaneous wound was created after administering 40 mg/kg streptozotocin intraperitoneally (STZ i.p.) to induce a diabetic (DB) animal model. Animals were divided into four groups: DB, DB+PB, DB+CCT, and DB+CCT+PB, each with six adult Albino rats. The wound edges were treated with a total of 300 µL of solution, consisting of 30 µL each of 100 µL 1×106 MSC, 100 µL SVF, and 100 µL PRP as CCT. PB was administered orally at a dose of approximately 200 mg daily. Histochemical analyses were performed using hematoxylin and eosin (HE) and Masson’s trichrome (MT). Immunohistochemical analyses were conducted for endothelial nitric oxide synthase (eNOS), Caspase-3, interleukin-10 (IL-10), vascular endothelial growth factor (VEGF), and Collagen I. The intestinal microbiome was examined through metagenomic analyses of taxonomic structure.  \nRESULTS: Combined cellular therapy provided more effective and faster healing in DB animals. It was discovered that PB further accelerated this process, leading to greater improvement. CCT was observed to reverse high eNOS, Caspase-3, and IL-10 expression, as well as low VEGF and Collagen I levels. Moreover, PB therapy significantly enhanced the positive effects of CCT. CCT in combination with PB significantly improved wound healing by preventing oxidative stress, apoptosis, and inflammation, while promoting vascularization and collagen organization.  \nCONCLUSION: Probiotic support was considered important for diabetic wound healing and was suggested to improve patients’quality of life.  \nKeywords: Cell therapy; diabetic skin; rat; probiotics; wound healing.  \nINTRODUCTION  \nDiabetes-related wound ulcers are slow-healing and costly complications characterized by impaired vascularization, inflammation, oxidative stress, apoptosis, and reduced signaling that are important for healing. Mesenchymal stem cells (MSC), platelet-rich plasma (PRP), and stromal vascular fraction (SVF)  \nare frequently used to treat these disorders, providing an effective therapeutic strategy.  \nMesenchymal stem cells are vital for treatment due to the cellular support they provide, the growth factors they release, and the regenerative environment they create.[1] PRP has gained popularity in recent years, both for its growth factors and for the support it offers to MSC. SVF is widely used in  \n\n| Cite this article as: Karakayalı EM, Tuğlu İ. The contribution of probiotics to cellular therapy in skin wound healing in diabetic rats.
