The purpose of this study is to see if a positron emission tomography/computed tomography (PET/CT) scan and a magnetic resonance imaging (MRI) of the chest can assess changes in the thymus size and function. The researchers would like to monitor the thymus with a PET/CT scan and a MRI before and after the participants transplantation.

The objective of this study is to evaluate the safety and effectiveness of administering high-dose chemotherapy followed by infusion of autologous CD34-selected peripheral blood stem cells...
Pilot Study of Total Body Irradiation in Combination With Cyclophosphamide, Anti-Thymocyte Globulin, and Autologous CD34-Selected Peripheral Blood Stem Cell Transplantation in Children With Refractory Autoimmune Disorders
OBJECTIVES: I. Determine the safety and long term complications of total body irradiation in combination with cyclophosphamide, anti-thymocyte globulin, and autologous CD34-selected periph...
Donor: This clinical study will evaluate the feasibility of a purified CD34 peripheral blood progenitor cell (PBPC) transplants in patients with hematological malignancies. The pri...
Trial of Allogeneic Stem Cell Transplants From HLA Compatible, Related and Unrelated Donors After a Myeloablative Preparative Regimen With Hyperfractionated TBI, Thiotepa and Fludarabine For Adult Patients With Lymphohematopoietic Disorders
This is a phase II, single-center study to evaluate the efficacy of a novel cytoreductive regimen followed by CD34+E- selected T cell depleted allogeneic stem cell (or soybean agglutinated...
Primary objective: To assess the differences in the overall survival at 3 years of a CD34+ cell selection versus no selection of hematopoietic progenitor cells harvested during peripheral...
The effectiveness of preemptive treatment (PET) for CMV in recipients of ex vivo T-cell depleted (TCD) hematopoietic cell transplantation (HCT) by CD34(+) selection is not well defined.
Blood circulation function of peripheral blood vessels in skin dermis was evaluated employing an optical sensor with a pressurization mechanism using the blood outflow and reflow characteristics. The ...
Umbilical cord blood (UCB) is an important graft source for hematopoietic stem cell transplantation (SCT). Due to less stringent human leukocyte antigen (HLA) matching criteria compared to bone marrow...
Human CD34(+) hematopoietic stem and progenitor cells (HSPCs) can reconstitute a human hemato-lymphoid system when transplanted into immunocompromised mice. While fetal liver- and cord blood-derived C...
MiRNAs and piRNAs from bone marrow mesenchymal stem cell extracellular vesicles induce cell survival and inhibit cell differentiation of cord blood hematopoietic stem cells: a new insight in transplantation.
Hematopoietic stem cells (HSC), including umbilical cord blood CD34+ stem cells (UCB-CD34+), are used for the treatment of several diseases. Although different studies suggest that bone marrow mesench...
A course or method of action selected, usually by a government, to guide and determine present and future decisions on population control by limiting the number of children or controlling fertility, notably through family planning and contraception within the nuclear family.
Providing an investigational therapy to a patient who is not eligible to receive that therapy in a clinical trial, but who has a serious or life-threatening illness for which other treatments are not available. Compassionate use trials allow patients to receive promising but not yet fully studied or approved therapies when no other treatment option exists. Also called expanded access trial.
Glycoproteins found on immature hematopoietic cells and endothelial cells. They are the only molecules to date whose expression within the blood system is restricted to a small number of progenitor cells in the bone marrow.
Transplantation of stem cells collected from the peripheral blood. It is a less invasive alternative to direct marrow harvesting of hematopoietic stem cells. Enrichment of stem cells in peripheral blood can be achieved by inducing mobilization of stem cells from the BONE MARROW.
Studies comparing two or more treatments or interventions in which the subjects or patients, upon completion of the course of one treatment, are switched to another. In the case of two treatments, A and B, half the subjects are randomly allocated to receive these in the order A, B and half to receive them in the order B, A. A criticism of this design is that effects of the first treatment may carry over into the period when the second is given. (Last, A Dictionary of Epidemiology, 2d ed)
Radiology is the branch of medicine that studies imaging of the body; X-ray (basic, angiography, barium swallows), ultrasound, MRI, CT and PET. These imaging techniques can be used to diagnose, but also to treat a range of conditions, by allowing visuali...
Organ transplantation is the moving of an organ from one body to another or from a donor site to another location on the patient's own body, for the purpose of replacing the recipient's damaged or absent organ. The emerging field of regenerative ...
