In the original version of this article (1), images of the same protein bands at different exposures were inadvertently used to represent CD44 expression in both MGC80-3 and AGS cells in Fig. 4D. The AGS CD44 bands have been replaced with the correct image in the latest online HTML and PDF versions of the article. The authors regret this error.
