rabbits have the capacity to regenerate holes in their ears by forming a blastema, a tissue that is made up of a group of undifferentiated cells. the purpose of the present study was to isolate and characterize blastema progenitor cells and compare them with marrow mesenchymal stem cells (mscs). five new zealand white male rabbits were used in the present study. a 2-mm hole was created in the a...

Objective(s) The use of co-culture cells as well as extra cellular matrix are among those strategies that have been employed to direct mesenchymal stem cell (MSC) bone differentiation in culture. In this regard, there is no study considering the effects of Matrigel on mesenchymal stem cell (MSC) in vitro bone differentiation. This was the subject of the present study. Materials and Methods ...

introduction: the use of cord stem cells, as a cell source for bone marrow reconstruction in patient under hematopoietic stem cell transplantation is enhancing. the amount of cd34+cells collected from cord blood compared to peripheral blood and bone marrow are less, but their collectionprocesure is easier. delay in freezing has negative effect on cells surveillance and reduce their ability in t...

Abstract Background Bone marrow mesenchymal stem cells are a potential resource for the clinical therapy of certain diseases. Canine, as companion animal, living in same space with human, is an ideal new model human diseases research. Because high prevalence diabetes, alternative transplantation islets (i.e. insulin producing cells) diabetes treatment will be urgent need, which makes our resear...

The bone marrow microenvironment comprises multiple cell niches derived from bone marrow mesenchymal stem cells. However, the molecular mechanism of bone marrow mesenchymal stem cell differentiation is poorly understood. The transcription factor GATA2 is indispensable for hematopoietic stem cell function as well as other hematopoietic lineages, suggesting that it may maintain bone marrow mesenc...

Background  In recent years, many researchers haveattempted to cure diabetes by using stem cells technology. Stem cells from different sources have capabilityto differentiateinto insulin producing cells (IPCs) by different methods. The obstaclesof these methods aretheirexpensive materials and complexity ofmethodswhichare practicallydisadvantagesfor producing enough transplantableIPCs that can ...

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...

OBJECTIVES Mesenchymal stem cells have the ability to differentiate into various cell types, and thus have emerged as promising alternatives to chondrocytes in cell-based cartilage repair methods. The aim of this experimental study was to investigate the effect of bone marrow derived mesenchymal stem cells combined with platelet rich fibrin on osteochondral defect repair and articular cartilage...
