Effect of ABI3 expression in invasion and migration. (A) WRO cells expressing ABI3 had a lower ability to migrate. The graphs display the mean ± SD of at least 12 spheroids of each clone. (B) The percentage of invasive cells through the Matrigel assay was lower in WRO cells expressing ABI3. Black bars correspond to control clones (n = 2) and white bars correspond to ABI3 expressing clones (n = 2).
