Abstract
Following the publication of this paper, the authors have realized that an error was made in the assembly of Fig. 1D: Specifically, the same image of migrated cells was selected for the 'Gas6' and 'HGF + Gas6' experiments pertaining to the A549 cells. The authors consider that they made this mistake during the process of copying and pasting images, owing to the similarity of the data concerned. A corrected version of Fig. 1, containing the correct data, is presented opposite. The authors sincerely apologize for this mistake, and regret any inconvenience this mistake has caused.
