Fig. 4.
Costimulatory/adhesion molecules in HL60 cells treated with ATRA.
Cells were incubated in the presence or absence of 10−7mol/L ATRA for 48 hours followed by flow cytometry (upper panel). The results of treatment with 0.7 mmol/L SB were shown for comparison (lower panel). Closed histograms (in black) represent medium-treated cells, whereas open histograms represent ATRA- or SB-treated cells.
