773“…We then performed a competitive repopulation assay on divided cells to ask if such cell division involved self-renewal of HSCs. In the presence of stem cell factor (SCF), thrombopoietin (TPO) induced a first cell division of CD34(−)KSL cells more efficiently than did interleukin (IL)-3 or IL-6. …”
