Following the publication of this article , it has been noted by the authors that an image of the same cell nuclei has been used in error twice, in Figure 8, parts A and B. These images are redundant in this figure as the images in parts D and E show Wnt3a treated and control cells stained with both Hoechst 33342 (as in parts A and B) and fluorescein diacetate. The data from multiple repetitions of the Hoechst 33342 stain experiment are presented in graph C. Thus, the duplicated images (in Figure 8A and 8B) add no additional data and do not change the results or conclusions reached in the article. The authors apologize for any confusion this may have caused.
