Recently, there has been increased implementation of bone marrow cell (BMC) transplantations in clinical settings to treat leukemia, lymphoma, and primary immunode—ciency disease.1 BMCs consist of various cell populations including hematopoietic stem cells (HSCs), mesenchymal stem cells, also known as multipotent stromal cells (MSCs), and endothelial progenitor cells (EPCs).2 Human HSCs
