The majority of patients with small cell carcinoma of the lung (SCCL) have bone marrow involvement detected by monoclonal antibodies (mAb). High dose chemotherapy followed by autologous bone marrow transplantation may improve treatment results for patients with SCCL, but the bone marrow may need to be purged of contaminating tumor cells. This study investigates the reactivity of a panel of mAb ...
background: marrow-derived mesenchymal stem cells (mscs) have been heralded as a source of great promise for the regeneration of the infarcted heart. there are no clear data as to whether or not in vitro differentiation of mscs into major myocardial cells can increase the beneficial effects of mscs. the aim of this study was to address this issue. methods: to induce mscs to transdifferentiate i...
Mice with inactivated TNF-LT alpha genes have profound abnormalities of the immune system with hypoimmunoglobulinaemia, lack of lymph nodes, undifferentiated spleen, and defective Ig class switch. Transplantation of bone marrow cells from wild-type mice restored the synthesis of TNF, corrected the splenic microarchitecture, repopulated the lamina propria with IgA-producing plasma cells, and nor...
cord blood is a rich source of hematopoietic stem cells and could be potentially used for transplantation instead of conventional sources of stem cells (bone marrow or peripheral blood). cord blood cells are successfully used in pediatric and adult patients, but their major limitation is the low number of hematopoietic stem cells for patients of large body size. there are several possible solut...
BACKGROUND Recent studies have shown that skeletal muscle-derived stem cells (MDSCs) can give rise to several cell lineages after transplantation. However, the potential therapeutic uses of MDSCs, the functional significance of the transplanted tissue, and vasculogenesis, myogenesis, and reconstitution of other tissues have yet to be investigated in detail. In addition, the relationship between...
Purpose: The aim is to downregulate the expression level of NS as an important factor in sustaining stem cells and certain types of cancer cells self-renewal ability in bone marrow derived mesenchymal stem cells by RNAi strategy and investigate the effects of absence of NS in these cells. Materials and Methods: Double strand NS-specific and control siRNA oligos were designed and transfected in...
Circulating progenitor cells home to sites of postnatal neovascularization and differentiate into endothelial cells but questions remain regarding the source of these cells. Indeed, a recent study suggests that nonbone marrow-derived cells may be even more important than bone marrow-derived cells in the setting of transplant arteriosclerosis. Thus, we aimed to thoroughly investigate the contrib...
background: the use of stem cells is considered as an appropriate source in cell therapy and tissue engineering. differentiation of human induced pluripotent stem cells (hipscs) to hepatocyte-like cells (hlcs) on mouse embryonic fibroblasts (mefs) feeders is confronted with several problems that hinder the clinical applications of these differentiated cells for the treatment of liver injuries. ...
BACKGROUND Cell therapy is a promising option to improve functional recovery after ischemia. Several subsets of bone marrow-derived cells were shown to reduce infarct size and increase ejection fraction in experimental models of ischemia. The mechanisms underlying the functional improvement are diverse and have been shown to include paracrine effects of the injected cells, as well as a variable...
Lymphoid and dendritic cells of donor origin can be detected in the recipient several years after a solid organ transplantation. This phenomenon is termed microchimerism and could play a role in the induction of tolerance. The fate of other hematopoietic cells transferred by liver transplantation, in particular of stem and progenitor cells, is unknown. For this reason, we studied peripheral blo...
