  • Here we describe the initial results of allogeneic bone marrow transplantation in three children with osteogenesis imperfecta, a genetic disorder in which osteoblasts produce defective type I collagen, leading to osteopenia, multiple fractures, severe bony deformities and considerably shortened stature. (nih.gov)
  • Experimental and clinical data gave encouraging results, showing that MSC injection allowed controlling refractory GVHD, restoring bone development in children with osteogenesis imperfecta or improving heart function after myocardial infarction. (staminafoundation.org)
  • These therapies decrease a patient's white blood cell counts, suppress bone marrow hematopoietic activity, and increase the patient's risk of infection and/or hemorrhage. (justia.com)
  • Current treatments to manage the problems that result from prolonged bone marrow suppression include the reinfusion of a patient's own previously harvested hematopoietic stem and progenitor cells. (justia.com)
  • Hematopoietic stem cell transplantation may be autologous (using the patient's own cells) or allogeneic (using cells from a donor). (msdmanuals.com)
  • We want to elucidate how hematopoietic perturbations and stressors are resolved on a clonal level by employing genetic barcoding. (digs-bb.de)
  • After lethal irradiation, the five animals were given 15-27 X 10(6) autologous marrow cells (3.2-4.4 X 10(6) cells/kg) containing 65-91% CD34+ cells. (nih.gov)
  • Today, more than 50 years after the first successful bone marrow transplantation, clinical application of hematopoietic stem cells is a routine procedure, saving the lives of many every day. (hindawi.com)
  • In principle, transplantation of mesenchymal progenitor cells would attenuate or possibly correct genetic disorders of bone, cartilage and muscle, but clinical support for this concept is lacking. (nih.gov)
  • Overall, this evidence has suggested that progenitor cell treatment may be a promising intervention, but robust data on clinical outcomes are lacking. (southcarolinablues.com)
  • This computational approach to the haematopoietic system is novel and provides insight into the dynamics and the nature of possible solutions, with potential applications in both fundamental and clinical research. (lu.se)
  • Donor CTLA-4 genotype influences clinical outcome after T cell-depleted allogeneic hematopoietic stem cell transplantation from HLA-identical sibling donors. (cdc.gov)
  • A few exceptions emerged when successful functional correction was exhibited in children with severe combined immunodeficiency (ADA-SCID and X-SCID) or chronic granulomatous disease following infusion of retrovirally transduced autologous CD34+ cells [12C14]. (eyesoftheelephants.com)
  • The specific effect on bone marrow fibrosis of JAK2 inhibition, and other rationally based therapies currently being evaluated in myelofibrosis, has yet to be fully elucidated. (haematologica.org)
  • We therefore briefly discuss differences found in subsets of human bmMSCs and in MSCs isolated from some other sources and touch upon how this could be utilized for cell-based therapies. (hindawi.com)
  • In addition to systemic treatments and/or targeted therapies, both autologous and allogeneic haematological progenitor transplantation (commonly called bone marrow transplantation) continues today to be part of the treatment plan for many patients with various haematological diagnoses such as leukaemia, lymphoma and multiple myeloma . (mdanderson.es)
  • Therefore, we aimed to identify cell surface proteins specifically expressed on NPM1)-mutated AML cells, allowing for potential targeting with antibody-based therapies. (lu.se)
  • We also have a long-standing interest in mast cells and the rare human disease mastocytosis, which is characterized by an abnormal accumulation of these cells in various organs. (digs-bb.de)
  • Transplantation of human organs and tissues1 saves many lives and restores essential functions in circumstances when no medical alternative of comparable effectiveness exists. (who.int)
  • The transplantation of solid organs, such as kidney, liver, heart or lung, is increasingly a regular component of health care in all countries, and is no longer a feature of health care in high-income countries alone. (who.int)
  • The persistent and widening gap between patients' need for organs and the number available for transplantation has become a major concern to many Member States. (who.int)
  • First, maintaining stem cell properties including repopulation potential during culture is usually a prerequisite of any successful gene transfer approach. (eyesoftheelephants.com)
  • In comparison to BM-MSCs without osteoinductive treatment, gene expression in e-MSCs was significantly altered in terms of their cell adhesion- and chemotaxis-related profiles, as identified with Gene Ontology and Gene Set Enrichment Analysis. (elsevierpure.com)
  • Quantitating the CD34+ cell population can also be useful during mobilization as well as for determining the optimal timing of apheresis sessions to make sure that enough CD34+ cells have been harvested. (bdbiosciences.com)
  • In many cases, successfully mobilization is not effected in the patient and inadequate numbers of hematopoietic stem cells are harvested from these patients using current methods. (justia.com)
  • This condition can rapidly lead to life-threatening infection, as the body cannot produce leukocytes in response to invading bacteria and viruses, as well as leading to anaemia due to a lack of red blood cells and spontaneous severe bleeding due to deficiency of platelets. (wikipedia.org)
  • Mature, differentiated cells that accompany the hematopoietic stem cells, disappear rapidly after transplantation as they lack the ability to self-renew. (ca.gov)
  • At steady-state, HSC infrequently divide and slowly but continuously spawn rapidly dividing progenitor cells. (digs-bb.de)
  • Thus homeostasis of T regulatory cells is an overbearing requirement for prevention of autoimmune disorders arising from uncontrolled self-tolerance which also permits malignancies to occur. (hoajonline.com)
