EFFECTS OF TRAUMA PLASMA-DERIVED EXOSOMES ON HEMATOPOIETIC PROGENITOR CELLS.

ABSTRACT:

Abstract

Background: Severe trauma disrupts bone marrow function resulting in persistent anemia and immunosuppression. Exosomes are extracellular vesicles implicated in disease, cellular functions, and immunomodulation. The effects of trauma plasma-derived exosomes on bone marrow hematopoiesis are unstudied; we hypothesized that trauma plasma-derived exosomes suppress bone marrow hematopoietic progenitor cell (HPC) growth and contribute to increased inflammatory cytokines and HPC mobilization. Methods: Plasma was collected from a prospective, cohort study of trauma patients (n = 15) with hip and/or femur fractures and an ISS > 15 and elective total hip arthroplasty (THA) patients (n = 15). Exosomes were isolated from both groups using the Invitrogen Total Exosome Isolation Kit. Hea
