Homoharringtonine (HHT) combined with arsenic trioxide (ATO) remarkably obliterated the histological infiltration of leukemia stem cells (LSCs). (a) H&E-stained sections of representative 4% paraformaldehyde-fixed spleens and bone marrow from NRG mice. (b) hCD45 and hCD34 levels were detected in the different groups by confocal laser-scanning microscopy in representative 4% paraformaldehyde-fixed spleens and bone marrow samples from NRG mice. Scale bars: 50 μm
