Retinoic acid induces neuronal differentiation of a cloned human embryonal carcinoma cell line in vitro.


The human embryonal carcinoma cell lines NT2 /D1 and NT2 /B9, clonally derived from Tera-2, differentiate extensively in vitro when exposed to retinoic acid. This differentiation is marked by the appearance of several morphologically distinct cell types and by changes in cell surface phenotype, particularly by the disappearance of stage-specific embryonic antigen-3 (SSEA-3), which is characteristically expressed by human EC cells. Among the differentiated cells are neurons, which form clusters interconnected by extended networks of axon bundles, and which express tetanus toxin receptors and neurofilament proteins. These observations constitute the first instance of extensive somatic differentiation of a clonal human EC cell line in vitro.
