Fig. 2.
Immunophenotypic profile of DAA-3 cells growth-arrested by RA and reversed by HC.
Cells were treated with 10−6 mol/L 13-cis-RA for 6 days and then replated either in medium alone or with 10−6 mol/L HC (indicated as RA + HC). Immunophenotype was evaluated after 7 days of culture, when cells exposed to HC fully recovered their proliferation. Data relative to the percentage of positive cells (A) and mean fluorescence intensity (B) are shown. The results of 1 representative experiment out of 3 are reported. Similar findings were observed with Dex.
