Various independent studies indicate involvement of different populations of bone marrow-derived stem cells in the process of tissue regeneration. In inflammatory disorders bone marrow stem cells are mobilized into peripherial blood and further to different organs, where they take part in tissue regeneration. Experimental studies have shown that bone marrow stem cells play a pivotal role in regeneration of endo and egzocrine pancreas and have a role in pathogenesis of pancreatitis, diabetes and pancreatic neoplasms...

Diabetic peripheral neuropathy (DPN) remains one of the most common and serious complications of diabetes. Currently, pharmacological agents are limited to treating the pain associated with DPN, and do not address the underlying pathological mechanisms driving nerve damage, thus leaving a significant unmet medical need. Interestingly, research conducted using exercise as a treatment for DPN has revealed interleukin-6 (IL-6) signaling to be associated with many positive benefits such as enhanced blood flow and lipid metabolism, decreased chronic inflammation, and peripheral nerve fiber regeneration...

Metformin, a first-line anti-diabetic drug used by millions of patients has been shown to have potential osteogenic properties. The present study was performed to test the hypothesis that clinically relevant doses of metformin promote the osteogenic differentiation and mineralization of induced Pluripotent Stem Cell-derived Mesenchymal Stem Cells (iPSC-MSCs). iPSC-MSCs were treated with metformin (10 μM) to assess cell viability, osteogenic differentiation, mineralization, and activation of the LKB1/AMP-activated protein kinase (AMPK) signaling pathway, a surrogate marker of metformin action...

In spite of modern techniques, the burden for patients with type 1 diabetes (T1D) will not disappear and T1D remains a life-threatening disease causing severe complications and increased mortality. We have to learn how to preserve residual insulin secretion or even increase beta cell regeneration. This would give a milder disease, simpler treatment and perhaps even cure. Thus, there are good reasons to try therapies that may preserve beta cell function. Areas covered: In this review the author reviews the literature and registered ongoing trials using GAD-alum put in relation to the high number of published different immune interventions...

Diabetes mellitus is a disease which has affected 415 million patients in 2015. In an effort to replace the significant demands on transplantation and morbidity associated with transplantation, the production of β-like cells differentiated from induced pluripotent stem cells (iPSCs) was evaluated. This approach is associated with promising decellularized scaffolds with natural extracellular matrix (ECM) and ideal cubic environment that will promote cell growth in vivo. Our efforts focused on combining decellularized rat pancreatic scaffolds with mouse GFP(+)-iPSCs-derived pancreatic β-like cells, to evaluate whether decellularized scaffolds could facilitate the growth and function of β-like cells...

Mesenchymal stem cells (MSCs) had been reported as a novel therapeutic strategy for non-healing diabetic cutaneous wound mainly by promoting the formation of extracellular matrix (ECM) and neovasculature. Collagen regeneration is one of the key processes of ECM remodeling in wound healing. Accordingly, rapid assessment of the collagen content in a noninvasive manner can promptly provide objective evaluation for MSC therapy of cutaneous wound healing and strength evidence to adjust therapeutic regimen. In the present study, noninvasive Raman microspectroscopy was used for tracing the regeneration status of collagen during diabetic wound healing with MSCs...

The wound healing process requires enough blood to supply nutrients and various growth factors to the wound area. However, chronic wounds such as diabetic skin ulcers have limited regeneration due to a lack of cellular and molecular signals because of a deficient blood flow. Mesenchymal stem cells (MSCs) are known to provide various factors including growth factors, cytokines and angiogenic mediators. Although MSCs have great therapeutic potential, their transplantation has many obstacles including the time required to culture the cells, the invasiveness of the procedure and limited stem cell sources...

Abrogation of ICOS/ICOS ligand (ICOSL) costimulation prevents the onset of diabetes in the non-obese diabetic (NOD) mouse but, remarkably, yields to the development of a spontaneous autoimmune neuromyopathy. At the pathological level, ICOSL(-/-) NOD mice show stronger protection from insulitis than their ICOS(-/-) counterparts. Also, the ICOSL(-/-) NOD model carries a limited C57BL/6 region containing the Icosl nul mutation, but, in contrast to ICOS(-/-) NOD mice, no gene variant previously reported as associated to NOD diabetes...

The wound healing process initiates after injury to a tissue and involves a series of orchestrated events to minimize the invasion of foreign matters such as bacteria and efficiently regenerate the damaged tissue. A variety of cells must be recruited to the tissue during wound healing. However, this process is severely disrupted in patients suffering from chronic illness, including diabetes, leading to impaired healing or non-healing wounds. Current avenues of treatment include negative-pressure therapy, wound debridement, growth factor replacement, and cell-based therapies...

Diabetic kidney disease (DKD) is a major complication of diabetes, and serves as an important cause of end-stage renal disease (ESRD). The role of chronic inflammation in DKD is becoming widely accepted. Pancreatic stone protein/regenerating protein (PSP/reg) is a secretory protein, which is elevated in blood during infected conditions and organ failure. The aim of this study was to investigate the relationship between serum PSP/reg and DKD in patients with type 2 diabetes (T2DM). A total of 120 subjects which includes newly diagnosed T2DM patients, diabetes patients without DKD, DKD patients, as well as healthy controls were enrolled in this study...

Identification of a specific biomarker for cancer stem cells (CSCs) is of potential applications in the development of effective therapeutic strategies for renal cell carcinoma (RCC). In this study, both the RCC cell line 786-O and surgically removed clear cell RCC (ccRCC) tissues were implemented to grew as spheroids in serum-free medium supplemented with mitogens. This subpopulation possessed key characteristics defining CSCs. We also identified that surgically removed ccRCC tissues were heterogenic and there was a subpopulation of cells that was highly stained with rhodamine-123...
