Relationship between Molecular Chimerism and Graft Versus Host Disease after Allogenic Hematopoietic Stem Cell Transplantation
Background: Bone marrow transplantation (BMT) is considered as a curative therapy for a broad range of diseases. However, complications such as relapse and graft versus host disease (GVHD) may be observed following BMT. Chimerism analysis serves as a reliable indicator of transplant outcome. Complete chimerism refers to the complete replacement of hematopoietic system by donor cells, while mixe...
متن کاملPediatric Hematopoietic Stem Cell Transplantation
The introduction and evolution of hematopoietic stem cell transplantation (HSCT) could be traced back to 1950s, to the studies on interactions among irradiation, covering spleen and bone marrow from it and injection of bone marrow cells. Today, HSCT is considered a well-established, effective and promising means of therapy for various malignant and non-malignant medical conditions, both in chil...
متن کاملHuman pulmonary chimerism after hematopoietic stem cell transplantation.
Many of the body's tissues once thought to be only locally regenerative may, in fact, be actively replaced by circulating stem cells after hematopoietic stem cell transplantation. Localization of donor-derived cells ("chimerism") has recently been shown to occur in the lungs of mice after either hematopoietic stem cell transplantation or infusion of cultured marrow. To determine whether tissues...
متن کاملPrevalence of chimerism after non-myeloablative hematopoietic stem cell transplantation.
CONTEXT AND OBJECTIVE Non-myeloablative hematopoietic stem cell transplantation (NMA-HSCT) is performed in onco-hematological patients who cannot tolerate ablative conditioning because of older age or comorbidities. This approach does not completely eliminate host cells and initially results in mixed chimerism. Long-term persistence of mixed chimerism results in graft rejection and relapse. Inv...
متن کاملDigital PCR Panel for Sensitive Hematopoietic Chimerism Quantification after Allogeneic Stem Cell Transplantation
Accurate and sensitive determination of hematopoietic chimerism is a crucial diagnostic measure after allogeneic stem cell transplantation to monitor engraftment and potentially residual disease. Short tandem repeat (STR) amplification, the current "gold standard" for chimerism assessment facilitates reliable accuracy, but is hampered by its limited sensitivity (≥1%). Digital PCR (dPCR) has bee...
