FGF2 and bronchiolitis obliterans syndrome: In a similar comparison, we noted decreased concentration of FGF-2 in astrocytes (42 pg/ml medium vs. 32 pg/ml for BO and 21 pg/ml for FOM), in hOPCs (78 pg/ml medium vs. 52 pg/ml for BO and 69 pg/ml for FOM), and in OL culture medium (85 pg/ml medium vs. 52 pg/ml for BO and 67 pg/ml for FOM) after exposition to both tested oils.
