Introduction: Type 1 diabetes mellitus (T1D) disease is caused by lesions or dysfunction of beta cells of pancreatic islets, causing less insulin to be secreted into the blood and thereby increasing glucose levels in the blood. In this study, we evaluated and compared the efficiency of treatment for T1D using autograft and allograft adipose-derived stem cells (ADSCs). Methods: ADSCs were collected from the belly of mice before they were injected using a single dose of streptozotocin (100 mg/kg) to induce T1D. T1D mice were intravenously injected with a dose of 2x106 ADSCs into the tail vein. Therapeutic efficacy was assessed by survival rate, blood glucose levels, serum insulin levels, histology and immunohistochemistry of pancreatic islets. Results: The results showed that both autograft and allograft transplantation of ADSCs demonstrated similarities in mortality rate, blood glucose level, blood insulin level, quantity and size of pancreatic islets. Both transplantations significantly improved T1D mice, which showed a decrease in mortality rate as well as blood glucose level, and increases in blood insulin level, quantity and size of pancreatic islets. Conclusion: The similar results suggest that both autologous and allogeneic transplantations of ADSCs are promising therapy for T1D treatment.

Context: Recently we showed that a 10-sec maximal sprint effort performed before or after moderate intensity exercise can prevent early hypoglycemia during recovery in individuals with type 1 diabetes mellitus (T1DM). However, the mechanisms underlying this protective effect of sprinting are still unknown. Objective: The objective of the study was to test the hypothesis that short duration sprinting increases blood glucose levels via a disproportionate increase in glucose rate of appearance (Ra) relative to glucose rate of disappearance (Rd). Subjects and Experimental Design: Eight T1DM participants were subjected to a euglycemic-euinsulinemic clamp and, together with nondiabetic participants, were infused with [6,6-2H]glucose before sprinting for 10 sec and allowed to recover for 2 h. Results: In response to sprinting, blood glucose levels increased by 1.2 ± 0.2 mmol/liter (P < 0.05) within 30 min of recovery in T1DM participants and remained stable afterward, whereas glycemia rose by only 0.40 ± 0.05 mmol/liter in the nondiabetic group. During recovery, glucose Ra did not change in both groups (P > 0.05), but glucose Rd in the nondiabetic and diabetic participants fell rapidly after exercise before returning within 30 min to preexercise levels. After sprinting, the levels of plasma epinephrine, norepinephrine, and GH rose transiently in both experimental groups (P < 0.05). Conclusion: A sprint as short as 10 sec can increase plasma glucose levels in nondiabetic and T1DM individuals, with this rise resulting from a transient decline in glucose Rd rather than from a disproportionate rise in glucose Ra relative to glucose Rd as reported with intense aerobic exercise.

Background: Many studies suggested adipose derived stem cell (ASC) transplantation as a new approach to control hyperglycemia in type 1 diabetes mellitus. It is proposed that the effects of these cells could be not only based on the direct cell-cell interaction but also the secretion of cytokines. This study aimed to demonstrate the effect of adipose stem cell-derived conditioned medium (CM) on the treatment of STZ-induced diabetic mice.  Methods: CM was obtained from 24-hours-cultured medium of ASCs and centrifuged to remove the debris. Type 1 diabetic mice were intraperitoneally injected CM for 30 consecutive days. Therapeutic efficacy of CM was assessed by survival rate, blood glucose level, serum insulin level, histological structure of pancreatic islets. Results: The results showed that CM treatment could decrease mortality rate (from 33,33% to 0%) as well as blood glucose level (from 425,667±65,753 mg/dl to 203,500 mg ±20,350 mg/dl) and enhance insulin secretion, improve size and function of pancreatic islets of diabetic mice.  Conclusion: Conditioned medium maybe a promising therapy for type 1 diabetes mellitus.

Type 1 diabetes mellitus is characterized by the destruction of pancreatic β-cells and requires the regeneration of these destroyed pancreatic β-cells for radical treatment. The degeneration of organelles in stem cells compromises stem cell quality; however, organelles in the mesenchymal stem cells of patients with type 1 diabetes mellitus have not been characterized previously. In this study, we use transmission electron microscopy to evaluate the degeneration of organelles in adipose-derived stem cells of patients with type 1 diabetes mellitus (T1DM ADSCs). Compared to adipose-derived stem cells from healthy humans, T1DM ADSCs degenerate differently, characterized by prominent enlarged spherical vesicles. The exosomes of T1DM ADSCs are found to be enlarged, reduced in number, and increased in the percentage of those positive for tetraspanin CD9. The findings of this study provide insight into the characteristics of stem cells in patients with type 1 diabetes mellitus.

Diabetes affects over 350 million people worldwide, with the figure projected to rise to nearly 500 million over the next 20 years, according to the World Health Organization. Insulin-dependent diabetes mellitus (type 1 diabetes) is an endocrine disorder caused by an autoimmune reaction that destroys insulin-producing -cells in the pancreas, which leads to insulin deficiency. Administration of exogenous insulin remains at the moment the treatment mainstay. This approach helps to regulate blood glucose levels and significantly increases the life expectancy of patients. However, type 1 diabetes is accompanied by long-term complications associated with the systemic nature of the disease and metabolic abnormalities having a profound impact on health. Of greater impact would be a therapeutic approach which would overcome these limitations by better control of blood glucose levels and prevention of acute and chronic complications. The current efforts in the field of regenerative medicine are aimed at finding such an approach. In this review, we discuss the time-honored technique of donor islets of Langerhans transplantation. We also focus on the use of pluripotent stem and committed cells and cellular reprogramming. The molecular mechanisms of pancreatic differentiation are highlighted. Much attention is devoted to the methods of grafts delivery and to the materials used during its creation.
