BACKGROUND Reversible ischaemia/reperfusion (I/R) liver injury has been used to induce engraftment and hepatic parenchymal differentiation of exogenous beta2-microglubulin(-)/Thy1(+) bone marrow derived cells. AIM To test the ability of this method of hepatic parenchymal repopulation, theoretically applicable to clinical practice, to correct the metabolic disorder in a rat model of congenital...

Background Bone marrow transplantation (BMT)is nowadays used in various hematological disorders including leukemias. Hemophilia A & B are sex linked bleeding disorders in which there are various genetic abnormalities in factor VIII & IX genes. Among various hematological disorders, bleeding disorders mainly hemophilia in now widely treated using plasma derived and recombinant factor VIII & IX ...

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...

Spermatogenesis is a self-renewing process leading to production of spermatozoa in adult testis. The existence of male germinal stem cells was demonstrated by regeneration of spermatogenesis after transplantation of total testicular germ cells in testis [1], and we have previously shown that mouse testicular cells contain a side population (SP) of stem cells (Hoechst 33342 fluorescent dye efflu...

Most studies regarding the marrow-derived equine mesenchymal stem cells (MSCs) have mainly focusedon the cell transplantation without considering the capacity of differentiation and in vitro requirements of thecells. These concerns were investigated in the present study. Equine MSCs were isolated from the sternalmarrow aspirates and expanded through two successive subcultures. Passage-2 equine ...

background: bone marrow-derived mesenchymal cellscan transdifferentiate into cardiomyocyte cells and improveheart function after transplantation. since biomaterials canimprove the cell retention in the site, cell survival and differentiation,heart tissue engineering is now being explored as anapplied solution to support cell-based therapies and increasetheir efficacy for myocardial diseases. ch...

Osteoarthritis (OA) is a prevalent chronic disease impacting on quality of life and has societal and economical burden increasing with age. Yet, no confirmed pharmacological, biological or surgical therapy could prevent the progressive destruction of OA joint. Mesenchymal stem cells (MSCs) with immunosuppressive activities emerged a potential therapy. We describe a magnetic resonance images (MR...

Multipotent adult progenitor cells (MAPCs) are bone marrow-derived stem cells that have extensive in vitro expansion capacity and can differentiate in vivo and in vitro into tissue cells of all 3 germinal layers: ectoderm, mesoderm, and endoderm. The origin of MAPCs within bone marrow is unknown. MAPCs are believed to be derived from the bone marrow stroma compartment as they are isolated withi...

It is generally believed that the cardiac myocytes withdraw from the cell cycle shortly after birth and thereafter any loss of myocardial tissue cannot be repaired. However, recent reports indicate that cardiac myocytes can be regenerated by stem cells derived from bone marrow in the damaged hearts. In this study, we investigated whether bone marrow-derived cells can differentiate into cardiac ...

introduction demyelination is a common lesion of spinal cord injury; cell therapy is an approach for replacing the lost oligodendrocytes. objective in this study, bone marrow stromal cells (bmscs) have been transdifferentiated into oligodendrocyte-like cells (olcs) and used in cytotherapy of contused spinal cords in rats. materials and methods the bmscs were collected from rat long bones, cultu...
