“EXTRACELLULAR VESICLES VARY WITHIN THE HUMAN HEMATOPOIETIC SYSTEM AND DIFFERENTIALLY INFLUENCE HEMATOPOIETIC STEM AND PROGENITOR CELLS “
Summary: Hematopoietic stem cells (HSC) are a rare population characterized by their unique ability to self-renew and differentiate into all lineage blood cells. HSCs reside in the bone marrow microenvironment, which is known to regulate the HSCs through the orchestration of a multitude of factors. Extracellular vesicles (EVs) are a heterogeneous group of nanoparticles delimited by a lipid bilayer and are believed to be released by all eukaryotic cells, including cells that comprise the bone marrow niche. EVs can transport biological cargo between cells as a form of intracellular communication, with the potential to induce functional changes in recipient cells. This project investigates whether EVs from distinct hematopoietic niches, namely peripheral blood plasma, bone marrow, and trabecular bone, play differing roles in regulating HSC quiescence, differentiation, and self-renewal. Understanding the interaction between HSCs and their microenvironment may aid in the development of regenerative medicine therapies for the treatment of hematopoietic diseases.
