objective(s) some investigation has indicated that adipose-derived stem cells possess different surface epitopes and differentiation potential according to the localization of fat pad from which the cells were derived. in the present study proliferation capacity and aging of such cells were explored. materials and methods adherent cells were isolated from the collagenase digests of adipose tiss...

The cartilage is a connective tissue that, due to the strength of its extracellular matrix, allows the tissue to tolerate mechanical stress without undergoing permanent deformation. It is responsible for the support of soft tissues and due to its smooth surface and elasticity, gives the joints the ability to slip and bend. excessive weight, excessive activity, or trauma can all cause cartilage ...

background: as condition and component of culture determine fate map of spermatogonial stem cells (sscs), the aim of this study was to evaluate of growth factors gdnf, lif and ra on proliferation and differentiation of ssc. materials and methods: sscs were cultured in two groups: the first group gdnf and lif and the second group ra. the number of clumps and colony formation was monitored during...

objective: evaluating the effects of p-benzoquinone and hydroquinone on the runx2 expression and osteoblastic differentiation of human marrow derived mesenchymal stem cells (mscs). materials and methods: bone marrow mscs obtained by cultivating marrow mononuclear cells, were exposed to 10μm of either p-benzoquinone or hydroquinone. following chemical treatment, runx2 gene expression was assess...

background: stem cell therapy in small animal medicineis still in its infancy and few in vitro and in vivo research projectsregarding animal mesenchymal stem cells (mscs) have beencarried out. on the other hand, cell tracking is the first step of thecell-based therapies and is essential to recognize cell fate posttransplantation. objectives: the aim of this study was toisolate, characterize, an...

background: the anticancer agent imatinib (im) is a small molecular analog ofatp that inhibits tyrosine kinase activity of platelet derived growth factors (pdgfs)and stem cell factor (scf) receptor in cancer cells. however these factors have a keyrole in regulating growth and development of normal sertoli, leydig and germcells.objective: the aim of this study was to determine cell viability, pd...

Arm grooves of star-fish have mesenchymal stem cells derived from adipose tissue cell. Widespread studies have shown that stem cells derived from adipose-derived mesenchymal stem cell from bone marrow have many similarities in terms of the ability to differentiate into a variety of tissues. Most of the animals live in warm and shallow waters and the waters of this feature is that it is low in d...
