In the article by W. Wang et al., entitled “Single Cell Behavior in Metastatic Primary Mammary Tumors Correlated with Gene Expression Patterns Revealed by Molecular Profiling,” which appeared in the issue of Cancer Research (pp. 6278–6288), Figures 2 and 3 appeared incorrectly. The correct figures and corresponding legends appear below and to the right.

In the article by V. L. J. Whitehall et al., entitled “Morphological and Molecular Heterogeneity within Nonmicrosatellite Instability-High Colorectal Cancer,” which appear in the issue of Cancer Research(pp. 6011–6014), Group C cancers should have been defined as MINT+ indicating that only 1–2 MINT markers were methylated.
