Brief Summary
This is a prospective observational study to determine the point after bone marrow transplant in adults and children at which the neutrophils derived from the transplanted stem cells are competent to form functional neutrophil extracellular traps (NETs). Furthermore, given the importance of platelet function for NET formation, we also plan to examine platelet activation and function as well as the platelet transcriptome using the same clinical samples.

Outcome Measures
Primary Outcomes (1)
Post-engraftment maturation of NET formation
The time to post-engraftment maturation of NET formation capability in PMNs isolated from pediatric and adult patients undergoing bone marrow transplantation will be measured by serial blood sampling/analysis over the course of a year after transplant.
1 year
Secondary Outcomes (1)
Post-engraftment platelet function
1 year
Study Arms (1)
Post bone marrow transplant
Patients who are undergoing bone marrow transplant, as well as patients who have completed a bone marrow transplant within the previous year.
Eligibility Criteria
Patients who are undergoing bone marrow transplant, as well as patients who have completed a bone marrow transplant within the previous year at Huntsman Cancer Institute and Primary Children's Medical Center will be identified as possible participants.
You may qualify if:
- Within one year of bone marrow transplant
- Informed consent
Contact the study team to confirm eligibility.
