Multifaceted secretion of htNSC-derived hypothalamic islets induces survival and antidiabetic effect via peripheral implantation in mice

We report that mouse hypothalamic stem/progenitor cells produce multiple pancreatic, gastrointestinal and hypothalamic peptides in addition to exosomes. Through cell sorting and selection according to insulin promoter activity, we generated a subpopulation of these cells which formed 3D spherical structure with combined features of hypothalamic neurospheres and pancreatic islets. Through testing streptozotocin-induced pancreatic islet disruption and fatal diabetes, we found that peripheral implantation of these spheres in mice led to remarkable improvements in general health and survival in addition to a moderate antidiabetic effect, and notably these pro-survival versus metabolic effects were dissociable to a significant extent. Mechanistically, secretion of exosomes by these spheres was essential for enhancing survival while production of insulin was important for the antidiabetic effect. In summary, hypothalamic neural stem/progenitor cells comprise subpopulations with multifaceted secretion, and this subpopulation-derived hypothalamic islets can be implanted peripherally to enhance general health and survival together with an antidiabetic benefit.

Metformin is the first-line medication for treatment of type 2 diabetes and has been shown to reduce heart damage and death. However, mechanisms by which metformin protects human heart remain debated. The aim of the study was to evaluate the cardioprotective effect of metformin on cardiomyocytes derived from human-induced pluripotent stem cells (hiPSC-CMs) and mitochondria isolated from human cardiac tissue. At concentrations ≤ 2.5 mM, metformin significantly increased oxygen consumption rate (OCR) in the hiPSC-CMs by activating AMPK-dependent signaling and enhancing mitochondrial biogenesis.

AbstractThe SGLT2 inhibitor empagliflozin improved cardiovascular outcomes in patients with diabetes. As the cardiac mechanisms remain elusive, we investigated the long-term effects (up to 2  months) of empagliflozin on excitation-contraction (EC)-coupling in human cardiomyocytes derived from induced pluripotent stem cells (iPSC-CM) in a blinded manner. IPSC from 3 donors, differentiated into pure iPSC-CM (4 differentiations), were treated with a clinically relevant concentration of em pagliflozin (0.5 μmol/l) or vehicle control. Treatment, data acquisition, and analysis were conducted externally blinded. Epif...

Authors: Yu L, Li M Abstract Vascular calcification, characterized by the active deposition of calcium phosphate in the vascular walls, is commonly observed in aging, diabetes mellitus and chronic kidney disease. This process is mediated by different cell types, including vascular stem/progenitor cells. The anti-aging protein klotho may act as an inhibitor of vascular calcification through direct effects on vascular stem/progenitor cells with osteogenic differentiation potential. A better understanding of the possible effects of klotho on vascular stem/progenitor cells may provide novel insight into the cellular an...

In this study, we investigated the therapeutic effect of exosomes derived from corpus cavernosum smooth muscle cells (CCSMC-EXOs) on erectile function in a rat model of diabetes and compared their effect with that of exosomes derived from mesenchymal stem cells (MSC-EXOs). We incubated labelled CCSMC-EXOs and MSC-EXOs with CCSMCs and then observed uptake of the exosomes at different time points using laser confocal microscopy. CCSMC-EXOs were more easily taken up by CCSMCs. The peak concentration and retention time of labelled CCSMC-EXOs and MSC-EXOs in the corpus cavernosum of DMED rats after intracavernous injection were...

AbstractAccumulating evidence has elucidated that human mesenchymal stem cells (hMSCs) exert profound analgesic effects on numerous animal models of neuropathic pain, including drug-induced peripheral nerves, diabetes-induced neuropathy, and chronic constriction injury. We aimed to address whether forcing expression of sirtuin 1 (SIRT1) can enhance the efficacy of hMSCs on alleviation of pain sensation. A rat model of chronic constriction injury (CCI) mimicking peripheral nerve injury was incorporated in the study. Paw withdrawal threshold (PWT) and paw withdrawal latency (PWL) testing were used to measure pain-related beh...

Objectives We aimed to determine whether responsive insulin-producing cells (IPCs) could be generated from adipose-derived stem cells (ADSCs) isolated from patients with type 1 diabetes mellitus (T1DM). Methods We isolated ADSCs from adipose tissue of 4 patients (one patient with T1DM and 3 nondiabetic patients), who underwent surgery and differentiated them into IPCs with using a 2-step xeno-antigen free, 3-dimensional culture method. Characteristics of isolated ADSCs, in vitro cell quality, programmed cell death ligand-1 (PDL-1) expression, and transplantation into streptozotocin induced diabetic nude mice were inve...
