Fig. 1From: Down regulation of G protein-coupled receptor 137 expression inhibits proliferation and promotes apoptosis in leukemia cellsRepresentative images of K562 (a) and HL60 (b) cells 5 days of after lentivirus transduction. Cells were either nontransduced (Con) or transduced with control lentiviral vectors (Lv-Con) or lentiviral vectors expressing shGPR137 (Lv-shGPR137) (magnification, ×100). The transduction efficiency was greater than 90%Back to article page
