objective: sulfur mustard (sm) is a potent mutagenic agent that targets several organs, particularly lung tissue. changes in morphological structure of the airway system are associated with chronic obstructive pulmonary deficiency following exposure to sm. although numerous studies have demonstrated pathological effects of sm on respiratory organs, unfortunately there is no effective treatment ...

background: rheumatoid arthritis is a type of inflammatory pain and is an autoimmune and chronic inflammatory disease which can lead to hyperalgesia, edema and decreased motor activity in affected area. mesenchymal stem cells conditioned medium (msc-cm) has anti-inflammatory mediators which can regulate the immune responses, alleviate inflammatory symptoms and has a paracrine effects too. the a...

Introduction In vitro expansion and differentiation of mesenchymal stem cells (MSCs) rely on specific environmental conditions. One crucial factor is the oxygen tension. Low oxygen tension improves MSC expansion in vitro. Moreover, it accelerates the induction of a chondrogenic phenotype in subsequent 3D differentiation cultures. However, clones of MSCs from the same donor often differ in their...

Background: The cultured mesenchymal stem cells (MSC) have been used in many clinical trials however, there are still some concerns about the cultural conditions. One concern is related to the use of FBS as a widely used xenogeneic supplement in the culture system. Human platelet-rich plasma (hPRP) is a candidate replacement for FBS. In this study, the effect of hPRP on MSC proliferation and os...

Mesenchymal stem/stromal cells (MSCs) and MSC-like multipotent stem/progenitor cells have been widely investigated for regenerative medicine and deemed promising in clinical applications. In order to further improve MSC-based stem cell therapeutics, it is important to understand the cellular kinetics and functional roles of MSCs in the dynamic regenerative processes. However, due to the heterog...

Following allogeneic hematopoietic stem cell transplantation (HSCT), interferon (IFN)-γ levels in the recipient's body can strongly influence the clinical outcome. Human umbilical cord-derived mesenchymal stem cells (UC-MSCs) are lucrative as biological tolerance-inducers in HSCT settings. Hence, we studied the molecular mechanism of how UC-MSCs influence natural killer (NK) cell-mediated IFN-γ...

tem cell biology has made cell-based therapies promising. While the use of human embryonic stem cells is ethically controversial, adult stem cells attracts more and more attention from clinicians and scientists. Adult mesenchymal stem cells (MSC) are derived from various tissues, including bone marrow, subcutaneous adipose tissue, cruciate ligament, muscle, and synovium,1 which are potential do...

Glioblastoma (GBM) is one of the most malignant and devastating brain tumors. The presence highly therapy-resistant GBM cell subpopulations within tumor mass, rapid invasion into tissues reciprocal interactions with stromal cells in microenvironment contributes to an inevitable fatal prognosis for patients. We highlight recent evidence crosstalk mesenchymal stem (MSCs), which occurs either by d...

Introduction: Acute tubular necrosis (ATN) is the most prevalent cause of acute renal failure (ARF). Mesenchymal stem cell transplantation has been studied as a potential treatment for renal dysfunction due to ATN. Inducible nitric oxide synthase (iNOS), bone morphogenetic protein-7 (BMP-7) and B-cell lymphoma 2 (Bcl-2) are surrogate markers of renal tubular epithelial regeneration and subseque...

Human mesenchymal stromal/stem cells (MSCs) are multipotent and currently undergoing hundreds of clinical trials for disease treatments. To date, no studies have generated induced MSCs from skin fibroblasts with chemicals or growth factors. Here, we established the first chemical method to convert primary human dermal fibroblasts into multipotent, induced MSC-like cells (iMSCs). The conversion ...
