(nationalacademies.org)
  • In this regard, recent findings of improved donor hematopoietic stem cell engraftment as the result of homing receptor manipulations by growth factors are promising. (nih.gov)
  • Thus, in recent years, treatment for bone defects using undifferentiated mesenchymal stem cells existing in vivo has attracted attention. (medsci.org)
  • In particular, among mesenchymal stem cells, bone marrow-derived stem cells are thought to be the major source of stem cells and are particularly attractive as donor cells in regenerative medicine because of their pluripotency. (medsci.org)
  • Bone marrow cells from C57BL/6-Tg (CAG-EGFP) mice were transplanted into C57BL/6 J wild type mice. (medsci.org)
  • METHODS: Lethally irradiated C57BL/6 mice were transplanted with bone marrow cells derived from wild-type or CCR7 C57BL/6 donor mice. (mdc-berlin.de)
  • In 2014, according to the World Marrow Donor Association, stem-cell products provided for unrelated transplantation worldwide had increased to 20,604 (4,149 bone-marrow donations, 12,506 peripheral blood stem-cell donations, and 3,949 cord-blood units). (wikipedia.org)
  • In a number of diseases (e.g., storage diseases), an early expression of donor cells activity (i.e., soon after transplant and before birth) is a critical requirement since even at birth significant clinical disease exists. (nih.gov)
  • In 2010, Ms. Ejedoghaobi heard about an NIH clinical trial for sickle cell disease that involved bone marrow transplantation. (nih.gov)
  • My clinical research interest is hematopoietic cell transplantation (HCT) for sickle cell disease and late effects following HCT. (unclineberger.org)
  • Additionally, I have a clinical interest in late effects that occur after HCT and hope one day to be able to develop a specific multidisciplinary HCT Late Effects/Survivorship clinic. (unclineberger.org)
  • Paczesny will use a combination of stored plasma and blood cell samples from the National Blood and Marrow Transplant Clinical Trials Network (BMTCTN). (musc.edu)
  • The objective of this study was to characterize the long-term rate of allergic sensitization and development of clinical allergic diseases following BMT from atopic donors. (notifylibrary.org)
  • Vincent Ho, MD, is the director of clinical operations for the Stem Cell Transplantation Program at the Dana-Farber Cancer Institute/Brigham and Women's Cancer Center. (cancer.net)
  • Blood and Marrow Transplant Research [CIBMTR] in 2004), the European Research Project on Cord Blood Transplantation (Eurocord) in 1993, and the Japanese Cord Blood Banking Network in 1996-expedited the clinical evaluation of the efficacy and safety of transplantation of cord blood from unrelated donors.

  • We therefore conducted a retrospective study to investigate the risk factors and causes of hip pain after orthotopic liver transplantation in order to provide useful information for our clinical practice. (jortho.org)
  • The risk of intrauterine transmission is highest when primary infection occurs during pregnancy, with a significantly increased risk of adverse fetal effects if fetal infection occurs during the first half of pregnancy. (medscape.com)
  • The technical and quality control issues that are involved when fetal donor stem cells are used may limit the applicability of this source of stem cells. (nih.gov)
  • Prior to the transplant, her brother underwent a treatment that made his marrow rich in stem cells. (nih.gov)
  • HPCs are traditionally collected from bone marrow with the donor in general anesthesia. (nih.gov)
  • Kim Kasow, DO, is the director of the Pediatric Bone Marrow Transplant Program, and professor in the Department of Pediatrics in the Division of Hematology-Oncology at UNC-Chapel Hill. (unclineberger.org)
  • PBPC transplantation offers faster hematopoietic recovery and lower early transplant-related morbidity and mortality. (nih.gov)
  • We thought that if we could transfer healthy bone marrow stem cells to an adult sickle cell patient, then the patient would start producing normal red blood cells and the patient would no longer have sickle cell disease," Dr. Tisdale said. (nih.gov)
  • In contrast to the established method in children, this adult trial sought to reduce toxicity by only partially replacing the bone marrow. (nih.gov)
  • This can also occur in adult males. (asgct.org)
  • Preparation for transplantation including conditioning regimen. (bookimed.com)
  • I currently am a co-principal investigator of a multi-center study evaluating the safety and efficacy of using a reduced intensity conditioning regimen in children with varying severity and genotype who are receiving a matched sibling donor bone marrow transplant. (unclineberger.org)
  • Continuing ART with a regimen that includes enfuvirtide post-alloBMT was safe, but life-threatening viral rebound can occur with ART interruption. (hopkinsmedicine.org)
  • Lymphoma - cancer occurs in the lymphatic system which affects the abnormal growth of immature lymphocytes that are unable to protect the body against infection. (yashodahospitals.com)
  • Lymphoma is a cancer of the lymphatic system, which comprises of the structures like the lymph nodes, spleen, thymus, bone marrow and vessels that carry the lymph fluid throughout the body. (yashodahospitals.com)
