E2F7 can regulate proliferation, differentiation, and apoptotic responses in human keratinocytes: implications for cutaneous squamous cell carcinoma formation (vol 69, pg 1800, 2009)

In the article on E2F7 in SCC in the March 1, 2009 issue of Cancer Research, data from murine keratinocytes was inadvertently shown instead of human epidermal keratinocytes. The corrected Fig. 2A appears below. The legend for Fig. 2A should read as follows: “A, the basal layer of the epidermis comprises TA keratinocytes and KSCs from which PMD keratinocytes of the suprabasal layers are derived. Cell fractions enriched for KSC, TA, and PMD cells were isolated from human epidermal tissue (Materials and Methods) based on their staining intensity for α6 (FITC-A) and CD71 (PE-A). Enriched fractions were reanalyzed and a representative merged image demonstrating the purity of the fractions is shown.” The conclusions and interpretation of the data in the article are unaltered by this correction.
