Neuronal differentiation of cloned human teratoma cells in response to retinoic acid in vitro.


We have analysed immunocytochemically the differentiation in vitro of clones of the human teratoma cell line Tera-2. The proliferating stem cells expressed Thy-1 and N-CAM/D2-CAM antigens. On treatment with 5 X 10(-5) M retinoic acid in either monolayer or aggregate cultures they began to express receptors for tetanus toxin and McAb A2B5. Three weeks after… (More)
