UNASSIGNED: @entity1778 stem cells (LSCs) are regarded as the origin of @entity1778 and its recurrence. Side population (SP) cells possess some intrinsic stem cell properties and contain numerous LSCs. In this study, we examined the prognostic significance of cluster differentiation 47 (CD47) and identified the appropriate target for eliminating LSCs. We determined the percentage of SP cells in a @entity1357 cell population and analyzed CD47 expression in different cell subsets. We then explored whether CD47 affected the phagocytic ability of macrophages to LSCs in vitro. Finally, the effect of anti-CD47 monoclonal antibodies, alone or combination with @entity2592 , against @entity1778 cells was evaluated in vitro and in vivo to identify the optimal targets for the treatment of @entity1778 . We observed an SP sub-fraction at low frequency (1.81    0.99%), which was a likely candidate for LSC enrichment. CD47 was more highly expressed on @entity1357 LSCs (P < 0.05) and was an independent predictor of survival and refractory disease in @entity1357 -engrafted @entity19 . Furthermore, the anti-CD47 monoclonal antibody stimulated preferential phagocytosis of LSCs by macrophages in vitro. Finally, single or combination treatment of @entity1357 LSC-engrafted @entity19 with @entity2592 and anti-CD47 antibody resulted in targeting of LSCs and depletion of @entity1778 cells. These findings suggest that CD47 is an antibody target in LSCs and combination treatment with @entity2592 and anti-CD47 monoclonal antibody represents an attractive option for the therapeutic targeting of @entity9020 .

@entity2592 and anti-CD47 antibody combination therapy eliminates XXXX @entity1357 cells in vivo and in vitro.
