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 se...

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...

Recent studies have implicated multipotential mesenchymal stem cells (MSCs) as an aid to breast cancer cell proliferation and metastasis, partly as a result of the MSCs secretome. As the tumor gets beyond 2 mm in diameter, the stromal cells could undergo starvation due to the lack of sufficient nutrients in solid tumor microenvironment. In this study, we investigated the survival mechanisms use...

Background and Aims: Previous studies have shown that adipose-derived mesenchymal stem/ stromal cells are one of the sources of mesenchymal stem cells (MSCs) with the capacity to differentiate into various mesodermal cell lineages. MSCs with cytokines secretion capability, which contributes to repair damaged tissues have gained wide credence for future cell-based therapeutic applications. In th...

Mesenchymal stem cells (MSCs) are multipotential cells with capability to form colonies in vitro and differentiate into distinctive end-stage cell types. Although MSCs secrete many cytokines, the efficacy can be improved through combination with neurotrophic factors (NTFs). Moreover, MSCs are excellent opportunities for local delivery of NTFs into injured tissues. The aim of this present study ...

background: mesenchymal stem cells (mscs) are ideal cells for cell and gene therapy. however, the low survival of mscs after transplantation has limited their applications. we aimed to evaluate the expression of cytoprotective genes including nqo1, txnrd1, ho-1, gclc following the over expression of nrf2 in umbilical cord-derived mscs (uc-mscs). methods: 3-5 passages of uc-mscs were cultured. r...

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...

Mesenchymal stem cells (MSCs) were officially named more than 25 years ago to represent a class of cells from human and mammalian bone marrow and periosteum that could be isolated and expanded in culture while maintaining their in vitro capacity to be induced to form a variety of mesodermal phenotypes and tissues. The in vitro capacity to form bone, cartilage, fat, etc., became an assay for ide...

Mesenchymal stem cells (MSCs) are increasingly becoming the focal point of research in regenerative medicine due to their potential differentiate into several different lineages including those non-mesodermal origin. With reports successful differentiation MSCs cell types such as osteocytes, chondrocytes, cardiocytes and even fully functional neurons, it is more important than ever understand s...
