Effects of BA on cell migration of glioma cells. Migration rates of U251MG and U343MG cells treated with BA analyzed by Boyden chamber assays (A) and scratch assays (B) under normoxic conditions. Compared to DMSO-treated control cells, incubation with 5, 10 and 20 μM BA led to a decrease in cell migration rates in both glioma cell lines. Similarly, cells had a reduced migration rate after BA treatment as measured by the scratch assay. Data represent the average values (± SD) of three independent experiments.
