HSCs express which type of cell-surface molecule, which is the receptor for stem cell factor (SCF). It is a cytokine that exists in both membrane-bound and soluble forms and the SCF-surface molecules interaction is critical for the development, in adult animals, of multipotential progenitor cells (MPPs).  Which type of surface molecules HSCs express?
