cellular and tissue activities highly depend on environmental ph. murine lung tissue, when cultured properly in-vitro, is a potent producer of hematopoietic growth factors. we have studied the effect of ph on the production of hematopoietic growth factors and protein synthesis by the murine lung in-vitro. various concentrations of nahc03 were used to adjust the ph of the culture medium under co...

Hematopoietic stem/progenitor cells (HSPCs) which give rise to different blood cell types are present within the bone marrow microenvironment, especially in flat bones such as skull, vertebrae, pelvis and chest. Interacting factors such as stromal derived factor-1/CXCR4, very late antigen-4/vascular cell adhesion molecule-1, Lymphocyte function-associated antigen-1/ intercellular adhesion molec...

Background The aim of this study was the ex vivo expansion of Umbilical Cord Blood hematopoietic stem cells on biocompatible nanofiber scaffolds. Materials and Methods CD133+ hematopoietic stem cells were separated from umbilical cord blood using MidiMacs (positive selection) system by means of monocolonal antibody CD133 (microbeads) subsequently, flowcytometry method was done to asses...

stem cell-based therapies have recently opened up new horizons for treatment of various types of diseases including diabetes mellitus. however, long-term efficacy and safety of these novel modalities still remain a serious question. hereby, we aim to report the one-year follow-up results in the diabetic patients who underwent fetal liver-derived hematopoietic stem cell allotransplantation. fift...

objective(s): stem cell differentiation into different cell lineages depends upon several factors, cell cycle control elements and intracellular signaling elements, including p15ink4b and p16ink4a genes. epigenetics may be regarded as a control mechanism which is affected by these factors with respect to their promoter structure.   materials and methods: the cd34 + cord blood stem cells were pu...

background: the study attempts to assess the relationship between chimerism analysis using polymerase chain reaction of short tandem repeat (str) and the incidence of chronic graft versus host disease (gvhd) as well as survival. methods: the retrospective cohort included all patients who received allo-hsct between 2005 to 2013. data collected by day +100 were reviewed in terms of the incidence ...

the  non-classical mhc  class-i mainly involves in the  regulation of  innate  immune responses where hla-e  plays a significant role in the cell identification by natural killer cells. hla-e is a main regulatory ligand for natural killer cells and given the importance of these effector cells in hematopoietic stem cell transplantation, we investigated the effect of hla-e polymorphisms on post-h...

background: this study explored the state of hematopoietic stem cell transplantation (hsct) recipient patients and problems experienced by them and nurse about these state and problems, in iran. methods: qualitative content analysis was used for analyzing semi-structured interviews with 12 hsct recipient patients and 18 nurses. results: three main categories described the hsct state and problem...

hematopoietic stem cell transplantation (hsct) has been practiced for more than 30 years. hematological malignanciesare the main indications for this treatment. however, its indications in adults are different from children.advances in chemotherapy and target therapy have improved treatment outcome of some of the very high riskcancers, and changed indications of hsct in children. multi-center c...
