Tumor formation constitutes a major obstacle to the clinical application of embryonic stem cell–derived (ESC-derived) cells. In an attempt to find major extracellular signaling and intrinsic factors controlling tumorigenicity and therapeutic functionality of transplanted ESC-derived retinal progenitor cells (ESC-RPCs), we evaluated multiple kinds of ESC-RPCs in a mouse retinal degeneration model and conducted genome-wide gene expression profiling. We identified canonical WNT signaling as a critical determinant for the tumorigenicity and therapeutic function of ESC-RPCs. The function of WNT signaling is primarily mediated by TCF7, which directly induces expression of

In Figure 4D, the merged image showing fTCF7, NESTIN, and BrdU staining of Vector-ESC-RPCs and the merged image showing SOX2, PCNA, and BrdU staining of ΔNTcf7-ESC-RPCs were mislabeled. The correctly labeled images are below.
