Pluripotent cells within embryonal carcinoma (EC) can differentiate in vivo or in vitro on treatment with specific agents. Differentiating EC cells express lower levels of stem cell-related genes, such as Cripto-1. We show that migration of human EC cells (NTEBA/2 and NCCIT) can be reduced following treatment with the guidance molecule Netrin-1. Moreover, Netrin-1 treatment increased the levels of ß-III tubulin, glial filament acidic protein, Nestin, and 7-aminobutyric acid and reduced the expressions of Cripto-1, Nanog, and Oct4 in EC cells. These Netrin-1-induced effects in the EC cells were mediated via binding of Netrin-1 to the Neogenin receptor and activation of SHP-2, resulting in increased levels of inactive phosphorylated c-src(YS27). These results suggest that Netrin-1 can induce neuroectodermal-like differentiation of human EC cells by affecting c-src signaling via SHP-2 activation and regulation of Nanog, Oct4, and Cripto-1 expressions.
