The other nominated gene---IGF-BP4---From the author

By using the very strict criteria to nominate genes that promote cardiomyogenesis, we found only two genes as candidates. Grem1 and IGF-BP4 were nominated as candidates. Grem1 indeed accelerated cardiomyogenesis of murine teratocarcinoma cells as published in this manuscript. It has just recently published in Nature (Zhu W, et al., IGFBP-4 is an inhibitor of canonical Wnt signaling required for cardiogenesis) that IGF-BP4 is involved in cardiogenesis. We did not include this information in this manuscript, page 2, Results section, the paragraph “GeneChip and statistical analysis”.
