(A) Representative images of HepG2 and HuH7 cell migration following exposure to 0.1 or 10% (v/v) fetal bovine serum (FBS), rhFABP4 (200 ng/mL), or 10% (v/v) FBS/rhFABP4 in the presence of SP 600,125 [SP; JNK inhibitor] (50 μM). U0126 [U0; ERK1/2 inhibitor] (10 μM), or SB 203,589 [SB; p38MAPK inhibitor] (20 μM). (B) Cumulative analysis of HepG2 and HuH7 cell migration (mean crystal violet fluorescent intensity). *P<0.05 versus 0.1% [v/v] FBS, #P<0.05 versus rhFABP4, N = 4.
