The area of hematopoietic stem cell transplantation (HSCT) has grown immensely since its beginnings. The roots of bone marrow transplantation (BMT) can be traced back to 1949 when Leon Jacobson and his colleagues performed mouse experiments and discovered that mice could recover from lethal irradiation if their spleens were shielded (Appelbaum, 1996). Lorenz, Uphoff, Reid, and Shelton demonstra...

Aim . To reveal the significance of major histocompatibility complex and human leukocyte antigen evolutionary divergence in transplantation allogeneic hematopoietic stem cells. The article traces evolution discusses reasons for its formation on example recognition system invertebrates, plants, jawed vertebrates humans. concepts immunopeptidome have been defined; data their impact therapy outcom...

Human leukocyte Antigen (HLA) mismatching leads to severe complications after solid-organ transplantation and hematopoietic stem-cell transplantation. The alloreactive responses underlying the posttransplantation complications include both direct recognition of allogeneic HLA by HLA-specific alloantibodies and T cells and indirect T-cell recognition. However, the immunogenicity of HLA mismatche...

THE BRAZILIAN SOCIETY FOR BLOOD AND MARROW TRANSPLANTATION (SBTMO) PRESENTS GUIDELINES ON HEMATOPOIETIC STEM CELL

OBJECTIVE The prominent functions of the local renin-angiotensin system (RAS) in primitive hematopoiesis further support the hypothesis that local autocrine bone marrow RAS could also be active in neoplastic hematopoiesis. The aim of this study is to examine critical RAS elements in normal CD34+ hematopoietic stem cells and multiple myeloma (MM)-related progenitor cells. MATERIALS AND METHODS...

THE BRAZILIAN SOCIETY FOR BLOOD AND MARROW TRANSPLANTATION (SBTMO) PRESENTS GUIDELINES ON HEMATOPOIETIC STEM CELL

CDC, the Infectious Disease Society of America, and the American Society of Blood and Marrow Transplantation have cosponsored these guidelines for preventing opportunistic infections (OIs) among hematopoietic stem cell transplant (HSCT) recipients. The guidelines were drafted with the assistance of a working group of experts in infectious diseases, transplantation, and public health. For the pu...

To examine whether donor-derived cells could exist in nonhematopoietic tissues of recipients after allogeneic hematopoietic stem-cell transplantation, we examined the patterns of the short tandem repeat (STR) of DNA extracted from fingernail clippings of recipients so that the contamination of blood cells was excluded. All 21 patients reached donor-derived hematopoiesis after transplantation an...

Cord blood hematopoietic stem cells are widely used as an alternative source for hematopoietic stem cells transplant. Increasing rate of patients who need hematopoietic stem cells transplant and many advantages of cord blood in comparison to bone marrow hematopoietic stem cells, have promoted banking of cord blood units. Cord blood banking requires accurate steps in donor selection, cord blood ...
