Figure S1. Anti-IL-6 antibody reduces Bel-7402 cell invasion.

(A) Representative images of invading Bel-7402 cells that treated as indicating. BMSC-CM and recombinant IL-6 promote Bel-7402 cell invasion. Anti-IL-6 antibody significantly reduced cell invasion of BMSC-CM pretreated Bel-7402 cells. (B) The calculated number of invading cells. Data were expressed by mean ± SEM from triplicates. #P<0.01, compared to BMSC-CM treated cells; *P<0.05, **P<0.01, compared to serum free medium treated cells.
