Induction of PPARγ target genes under different cell culture conditions. Transcript levels of FABP4 (A) and ABCG2 (B) were determined by qRT-PCR. RNA was obtained from monocyte-derived macrophages (MF) or monocyte-derived DCs in the presence or absence of 2.5 μM rosiglitazone (RSG). Cells were cultured in human AB serum (HS)– or fetal bovine serum (FBS)–containing cell culture medium as indicated. Error bars indicate the standard diviation (SD) of the relative expression.
