Mesenchymal stem cells (MSC) derived from white adipose tissue are considered to be an appropriate therapeutic candidate for various human diseases due their natural ability maintain homeostasis. They have also been use as a alternative sufficient availability and ease of harvesting. MSC play important role in the process adipogenesis energy metabolism that is directly related pathogenesis dege...

Objective(s):Mesenchymal stem cells (MSC) can be isolated from adult tissues such as adipose tissue and other sources. Among these sources, adipose tissue (because of easy access) and placenta (due to its immunomodulatory properties, in addition to other useful properties), have attracted more attention in terms of research. The isolation and comparison of MSC from these two sources provides a ...

Mesenchymal stem cells (MSC) have pushed the field of cell-based therapies by inducing tissue regeneration, immunosuppression, and angiogenesis mainly through vesicles soluble factors release (paracrine signaling). MSC-extracellular (MSC-EV) adaptable secretome homing to injured sites allowed researchers unlock a new era cell-free based therapy. In parallel, nanoparticles (NP) been explored in ...

CONTEXT Articular cartilage possesses poor natural healing mechanisms, and a variety of non-cell-based and cell-based treatments aim to promote regeneration of hyaline cartilage. DATA SOURCES A review of the literature to December 2013 using PubMed with search criteria including the keywords stem cell, cell therapy, cell transplantation, cartilage, chondral, and chondrogenic. STUDY SELECTIO...

introduction: chemokine receptors are found on the surface of stem cells. there have been 19 distinct chemokine receptors described in mammals. chemokines are major players in migration and homing. therefore, changes in their levels or function can help us to increase the migratory potential of these cells. valproic acid differs in structure from other drugs in common use. the way in which valp...

objectives: periodontal tissue regeneration for treatment of periodontal disease has not yet been mastered in tissue engineering. stem cells, scaffold, and growth factors are the three main basic components of tissue engineering. periodontal ligament (pdl) contains stem cells; however, the number, potency and features of these cells have not yet been understood. this study aimed to isolate and ...

background: it is still controversial that the stem cells isolated from human dental pulp meets the criteria for mesenchymal stem cells (mscs). the aim of the present study was to examine whether or not they are mscs, or are distinct stem cells population residing in tooth pulp.   methods: adherent fibroblastic cells in the culture of pulp tissue from human third molars were propagated through ...

Mesenchymal stem cells (MSC) are multipotential nonhematopoietic progenitor cells capable of differentiating into multiple mesenchymal tissues. MSC are able to reconstitute the functional human hematopoietic microenvironment and promote engraftment of hematopoietic stem cells. MSC constitutively express low levels of major histocompatibility complex-I molecules and do not express costimulatory ...

conclusions our data suggest that preconditioning with 5 μm h2o2 + 0.5% fbs and 10 μm h2o2 + 5% fbs improved cell proliferation and viability. however, the mechanisms related to protective properties of preconditioning and using this strategy in stem cell therapy requires more research. background mesenchymal stem cells (mscs) survival decreased following in vivo injection and its application h...

Objective(s): Cord blood (CB) is known as a valuable source of hematopoietic stem cells (HSC). Identifying strategies that enhance expansion and maintain engraftment and homing capacity of HSCs can improve transplant efficiency. In this study, we examined different culture conditions on ex vivo expansion and homing capacity of CB-HSCs. Materials and Methods: In this study, 4-5 different units o...
