The main barrier to the success of hematopoietic stem cell transplantation (HSCT) is acute graft versus host disease (aGVHD). The risk factors for aGVHD are mainly clinical and can be improved if additional biological factors are incorporated, such as the metabolomic profile. It is known that the levels of various metabolites measured are important in the process of immunoregulation. In our population study we investigated the systemic metabolic profile for 26 (Group I) allotransplant recipients...

Myocardial infarction (MI) is the leading cause of cardiovascular deaths and disability in the industrialized world. Although stem cells have been injected into hearts to limit MI damage, < 4% of stem cells remain in the heart for > 1 hour due to myocardial contractility which causes the rapid egress of the stem cells through the cardiac veins and lymphatics. We hypothesized that stem cells in chitosan gels would remain longer in the heart and therefore be more beneficial in MI repair....

Hypophosphatasia (HPP) is due to mutations in ALPL gene which encodes the tissue non-specific alkaline phosphatase isozyme (TNSALP). Defective/inactive TNSALP causes an increased concentration of inorganic pyrophosphate (PPi) in bone matrix that impairs bone mineralization. The accumulation of extracellular PPi observed in HPP causes impairment in bone mineralization process and leads to a disturbance of calcium and Pi homeostasis. The pathogenesis of bone hypomineralization in HPP is relatively...

Mesenchymal stem cells (MSCs) can be isolated from different adult tissues and can be differentiated along stromal lineages (i.e. osteoblasts, adipocytes, and chondrocytes). Recent data in the literature provided evidence that MSCs can also be differentiated in vitro into additional cell types, such as endothelial cells. In our studies we showed the endothelial differentiation and angiogenic potential of human neonatal foreskin derived stromal cells (hNSSCs) both in vitro and in vivo....

Implants of mammary glands from a single mammary fat pad in a H253 transgenic female mouse heterozygous for a lacZ-labeled X chromosome were analyzed at various time points following transplantation into the epithelium-cleared mammary fat pads of immune-compromised mice. The results show that the lacZ-marked X chromosome, demonstrated by nuclear-associated X-gal staining, was confined to a single epithelial clone that gave rise to the cap cells of all growing terminal end buds (TEB) in the expan...

Preliminary studies based on stem cells were initially applied to the clinical setting of acute myocardial infarction (AMI) with the purpose of delivering a cardioprotective effect. The field has then rapidly expanded to embrace chronic heart failure as a cardiorestorative therapy. For the easiness of collection as hematologic tissue, Bone Marrow (BM)-derived stem cells were utilized as the primary source of these applied therapies. Specifically, unselected Bone-Marrow Mononuclear Cells (BMMNCs)...

Mesenchymal stem cells (MSCs) are adult stromal cells with multi-lineage differentiation potential and immunomodulatory properties. They can be isolated relatively easily from several tissues, including bone marrow and adipose tissue and can be expanded ex vivo to yield the large numbers required for a therapeutic dose. As such, MSCs are considered a promising cell source that can be used in cellular therapy for a wide range of diseases, including bone and cartilage defects. However, despite the...

Human induced pluripotent stem cell (hiPSC) technology has widely been used for modeling of various genetic diseases. In the disease-modeling iPSC studies, it is necessary to generate hiPSC lines from peripheral tissues of multiple patients and of multiple age- and sex-matched control individuals in order to minimize the differences in genetic background that can affect the results. However, we can generate disease model-hiPSC line with mutant allele being expressing and normal control-hiPSC lin...

Several preclinical studies have shown potential immune-modulatory properties of mesenchymal stem cells (MSC) in type 1 diabetes leading to phase I/II clinical trials. Immune-modulatory properties of MSC have been mainly ascribed to their secretome. The extracellular vesicles (EV) have emerged as paracrine mediators of MSC actions. In fact, MSC-derived EV have been shown to carry proteins and nucleic acids capable to mimic the effect of originating cells. In the present short review we discuss e...

Diabetes mellitus is a disease characterized by progressive destruction of the beta cells in the pancreatic islets of Langerhans. The current primary treatment is changing the life style and insulin injection. However, this therapy cannot provide sustained physiological glycemic control. Pancreas or islet cell transplantation would be the preferred treatment options. However, the lack of donor tissue immunoincompatibility, cell rejection and using long term immunosuppression are the major barrie...

Embryonic stem cells (ES cells) have unique differentiation and self- renewal potential which makes them a potential candidate for cell therapy in degenerative disorders. However, the limitation of deriving ES cells from embryos and their immune-incompatibility hinder their clinical applications. Fortunately, by introduction of somatic cell reprogramming technology into induced pluripotent stem cells (iPS cells), the limitations of ES cells have been circumvented. Therefore iPS cells have been c...
