background: although the pathogenesis of diabetes type 1 (t1d) is not fully elucidated. different clusters of lymphocytes such as cd4+ and cd8+ t cells are involved in it. moreover, the mechanism of how stem-cell therapy results in significant therapeutic outcomes in diabetes remains obscure. in the current study, we aimed to analyze lymphocyte subsets in patients with t1d before and after trea...

stem cell therapy is a powerful technique for the treatment of a number of diseases. stem cells are derived from different tissue sources, the most important of which are the bone marrow (bm), umbilical cord (uc) blood and liver. human uc mesenchymal stem cells (huc-mscs) are multipotent, non-hematopoietic stem cells that have the ability to self-renew and differentiate into other cells and tis...

background: proliferation and expansion of cancer stem cells as spheroids were proved in previous studies. but, capability of primary tumor-derived stem cells to keep their unique properties in vitro is still disputed. so, the goal of this study was to isolate, expand and characterize of colon cancer-derived stem cells. material and methods: in the present work, colon cancer stem cells markers ...

germline and somatic stem cells are distinct types of stem cells that are dedicated to reproduction and somatic tissue regeneration, respectively. germline stem cells (gscs), which can self-renew and generate gametes, are unique stem cells in that they are solely dedicated to transmit genetic information from generation to generation. we developed a strategy for the establishment of germline st...

tissue engineering based on the adipose derived stem cells  promote a strong strategy to propagation of bone, cartilage and fat tissues in the three-dimensional scaffolds, fabricated by combining biological materials with suitable and appropriate growth factors.  in this study, a peo scaffold was used to show that mesenchymal stem cells can attach well; the aim of this study was the investigati...

In cell therapy and regenerative medicine, a reliable source of stem cells together with cytokine growth factors and biomaterial scaffolds seem necessary. As adipose tissue is easy accessible and is abundant source of adult stem cells and can differentiate along multiple lineages, it can be considered as a good candidate in aesthetic medicine. The clinical application of adipose-derived stem ce...

stem cells are self-renewing cells that can be differentiated into other cell types. conventional in vitro models for studying stem cells differentiation are usually preformed in two-dimensional (2d) cultures. the design of three-dimensional (3d) in vitro models which ideally are supposed to mimic the in vivo stem cells microenvironment is potentially useful for inducing stem cell derived tissu...

embryonic stem cells are capable of differentiating to variety of cell tissues including cardiomyocytes. this developmental change is accompanied with a great deal of ion channel expression and functions. mouse stem cell derived cardiomyocytes were prepared and separated to yield isolated single cell suspension for cell current recording. in the present study some properties of the k + -current...

background: recent publications about differentiation of stem cells to germ cells have motivated researchers to make new approaches to infertility. in vitro production of germ cells improves understanding differentiation process of male and female germ cells. due to the problem of using embryonic stem cells (esc), it’s necessary the mentioned cells be replaced with some adult multi-potent stem ...
