We analyzed the circulating stem cells, growth factor and anti-oxidant gene expression profiles in type 2 diabetes patients without or with different forms of DFS.<h4>Materials and methods</h4>Healthy volunteers (n = 13) and type 2 diabetes patients: (i) without DFS (n = 10); or with (ii) Charcot osteoneuropathy (n = 10); (iii) non-infected (n = 17); (iv) infected (n = 11); and (v) healed ulceration were examined (n = 12). Peripheral blood endothelial progenitor cells (EPC), mesenchymal stem cells (MSC), hematopoietic stem cells (HSC) and very small embryonic-like (VSEL) cells were phenotyped using flow cytometry. Plasma cytokine concentrations and gene expressions in blood cells were measured by Luminex and quantitative real-time polymerase chain reaction assays, respectively.<h4>Results</h4>Patients with non-complicated type 2 diabetes showed reduced HMOX1 expression, accompanied by HMOX2 upregulation, and had less circulating EPC, MSC or HSC than healthy subjects. In contrast, VSEL cells were elevated in the type 2 diabetes group. However, subjects with DFS, even with healed ulceration, had fewer VSEL cells, more CD45-CD29(+)CD90(+)MSC, and upregulated HMOX1 when compared with the type 2 diabetes group. Patients with Charcot osteopathy had lowered plasma fibroblast growth factor-2. Elevated plasma tumor necrosis factor-α and decreased catalase expression was found in all diabetic patients.<h4>Conclusions</h4>Patients with type 2 diabetes and different forms of DFS have an altered number of circulating stem cells. Type 2 diabetes might also be associated with a changed plasma growth factor and anti-oxidant gene expression profile. Altogether, these factors could contribute to the pathogenesis of different forms of DFS.Journal of diabetes investigationNumber of circulating pro-angiogenic cells, growth factor and anti-oxidative gene profiles might be altered in type 2 diabetes with and without diabetic foot syndrome.PMC402523902.02.00-00-014/0801.01.02.069/0902.01.00-12-064/08K/ZDS/002808POIG 01.01.02-00-109/09Dulak JBukowska-Strakova KWitek PBorys SKusinska KJozkowicz AKoblik TMalecki MTNowak WNfalseNumber of circulating pro-angiogenic cells, growth factor and anti-oxidative gene profiles might be altered in type 2 diabetes with and without diabetic foot syndrome.<h4>Aims/introduction</h4>Type 2 diabetes is often complicated by diabetic foot syndrome (DFS).
