Stem cells collected from sibling donors for allogenic transplants contain various types of cells. The predominant immune cells are called CD3+ T cells. The amount of these T cells vary vastly from donor to donor. This study is to determine if standardizing the CD3+ T cell dose will benefit the recipient (patient). As well as to help discover if dose standardization causes less variation in outcomes between patients and to make transplantation more predictable and complications easier to manage.
The optimal CD3+ cell dose to be used for allo HSCT is unknown. In addition, there are multiple variables in addition to CD3+ cell dose which affect engraftment, immune reconstitution, GVH and GVL in these patients including recipient age, diagnosis, disease status at transplantation, donor/recipient tissue type match, preparative regimen, and GVHD prophylaxis. Thus the ability to produce products with a fixed CD3+ content is critical to further research and ultimately to the definition of the "right dose" of CD3+ cells for various clinical situations.
Patients who meet eligibility criteria will receive a peripheral blood stem cell product from their original matched sibling donor engineered to deliver a dose of 3.0+/-0.5 x107 CD3+ cells/kg recipient body weight. Other components of the graft will not be manipulated and the recipient will receive the total number of cells collected with the exception of minimal losses that occur during the process of CD3+ T cell isolation.

The objective was to evaluate endocrine complications in survivors of hematopoietic stem cell transplantation (HSCT) performed during childhood.
Transfer of HEMATOPOIETIC STEM CELLS from BONE MARROW or BLOOD between individuals within the same species (TRANSPLANTATION, HOMOLOGOUS) or transfer within the same individual (TRANSPLANTATION, AUTOLOGOUS). Hematopoietic stem cell transplantation has been used as an alternative to BONE MARROW TRANSPLANTATION in the treatment of a variety of neoplasms.
The release of stem cells from the bone marrow into the peripheral blood circulation for the purpose of leukapheresis, prior to stem cell transplantation. Hematopoietic growth factors or chemotherapeutic agents often are used to stimulate the mobilization.
The transference of BONE MARROW from one human or animal to another for a variety of purposes including HEMATOPOIETIC STEM CELL TRANSPLANTATION or MESENCHYMAL STEM CELL TRANSPLANTATION.
Transplantation of STEM CELLS collected from the fetal blood remaining in the UMBILICAL CORD and the PLACENTA after delivery. Included are the HEMATOPOIETIC STEM CELLS.
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.
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 ...
