Murine hematopoietic stem cells change their surface phenotype during ex vivo expansion

Abstract excerpt

Ex vivo expansion of hematopoietic stem cells (HSCs) is important for many clinical applications, and knowledge of the surface phenotype of ex vivo-expanded HSCs will be critical to their purification and analysis. Here, we developed a simple culture system for bone marrow (BM) HSCs using low levels of stem cell factor (SCF), thrombopoietin (TPO), insulin-like growth factor 2 (IGF-2), and fibroblast growth...
