Developing Safer Stem Cell and Lymphocyte Selection Methods Using G-CSF Mobilized Blood from Healthy Adults for Bone Marrow Transplant Alternatives

What this Trial Is About

Researchers are studying bone marrow transplants BMT used to treat blood disorders like leukemia, focusing on reducing a serious complication called graft-versus-host disease GVHD. GVHD occurs when donor white blood cells attack the recipients tissues, potentially causing fatal reactions. This trial aims to improve methods that remove harmful lymphocytes from donor blood while preserving stem cells needed for healthy blood regeneration, and to understand how a growth factor called G-CSF affects immune cell function in transplantation. The study involves healthy volunteers who receive daily injections of G-CSF to stimulate stem cell production. Blood stem cells are then collected through a process called apheresis, and lymphocytes are removed from the collected cells. Researchers are developing and improving techniques for processing these cells to minimize the risk of GVHD while ensuring enough stem cells remain for successful transplantation. The collected cells will also be used for laboratory studies to better understand immune interactions. Participants undergo medical clearance before starting daily G-CSF injections, which may be administered at the clinical center or at home after training. Blood samples are collected and analyzed to evaluate cell processing methods and immune function. The main outcomes include developing reliable cell selection techniques and studying the effects of G-CSF on lymphocytes. This research contributes to making allogeneic transplantation safer and more effective, with total participation involving injections, blood collection, and laboratory assessments.
