Type 1 regulatory T cells are associated with persistent split erythroid/lymphoid chimerism after allogeneic hematopoietic stem cell transplantation for thalassemia

open access: yesHaematologica, 2009
Background Thalassemia major can be cured with allogeneic hematopoietic stem cell transplantation. Persistent mixed chimerism develops in around 10% of transplanted thalassemic patients, but the biological mechanisms underlying this phenomenon are poorly

Monitoring of donor chimerism in sorted CD34+ peripheral blood cells allows the sensitive detection of imminent relapse after allogeneic stem cell transplantation

open access: yesHaematologica, 2009
Analysis of donor chimerism is an important diagnostic tool to assess the risk of relapse after allogeneic stem cell transplantation, especially in patients lacking a specific marker suitable for monitoring of minimal residual disease.

Extensive multilineage analysis in patients with mixed chimerism after allogeneic transplantation for sickle cell disease: insight into hematopoiesis and engraftment thresholds for gene therapy

open access: yesHaematologica, 2020
Although studies of mixed chimerism following hematopoietic stem cell transplantation in patients with sickle cell disease (SCD) may provide insights into the engraftment needed to correct the disease and into immunological reconstitution, an extensive ...

Characterization of Tolerance Induction through Prenatal Marrow Transplantation: The Requirement for a Threshold Level of Chimerism to Establish Rather than Maintain Postnatal Skin Tolerance

open access: yesCell Transplantation, 2010
Hematopoietic chimerism resulting from prenatal marrow transplantation does not consistently result in allotolerance for unidentified causes. In a C57BL/6-into-FVB/N murine model, we transplanted T-cell-depleted adult marrow on gestational day 14 to ...

Early relapse prediction after allogeneic hematopoietic stem cell transplantation for acute lymphoblastic leukemia (ALL) using lineage‐specific chimerism analysis

open access: yeseJHaem, 2022
Relapse is a major cause of treatment failure after hematopoietic stem cell transplantation (HSCT) for acute leukemia. Here, we report a monocentric retrospective study of all HSCTs for B cell acute lymphoblastic leukemia (ALL) performed during the years

Stability of Chimerism in Non-Obese Diabetic Mice Achieved By Rapid T Cell Depletion Is Associated With High Levels of Donor Cells Very Early After Transplant

open access: yesFrontiers in Immunology, 2018
Stable mixed hematopoietic chimerism is a robust method for inducing donor-specific tolerance with the potential to prevent rejection of donor islets in recipients with autoimmune type-1 diabetes.

Chimerism and use of mesenchymal stem cells in umbilical cord blood transplantation

open access: yes, 2013
We performed a retrospective single-center analysis of 50 umbilical cord blood transplantations (UCBTs), focusing on chimerism development. Complete donor chimerism (DC) was associated with acute graft-vs.-host disease (aGVHD) grades II-IV for the CD3 (+)

Drawback of chimerism analysis by XY-fluorescence in situ hybridization: Deception of a relapse

open access: yesIndian Journal of Medical and Paediatric Oncology, 2020
Chimerism is monitored by various methods in posttransplant patients. Interphase fluorescence in situ hybridization (FISH) for XY (sex) chromosomes is one of the methods commonly employed.

Long-Term Stable Mixed Chimerism after Hematopoietic Stem Cell Transplantation in Patients with Non-Malignant Disease, Shall We Be Tolerant? [PDF]

open access: yesPLoS ONE, 2016
Long-term stable mixed chimerism is a rare and poorly understood phenomenon post hematopoietic stem cell transplantation. This study aims to shed light on whether the two hematopoietic systems in patients with mixed chimerism remain functional ...

Navigating preemptive and therapeutic donor lymphocyte infusions in advanced myeloid malignancies by high-sensitivity chimerism analysis

open access: yesFrontiers in Oncology, 2022
Preemptive and therapeutic donor lymphocyte infusions (preDLI and tDLI) are widely used in relapsing and relapsed hematopoietic malignancies after allogeneic stem cell transplantation (alloSCT) to enhance the graft-versus-malignancy effect.
