Picking epithelial, endothelial and neural cell lines - Please suggest best models (Apr/27/2009 )

Please help me picking cell lines for my experiments.
I need to chose one cell line for each model:
epithelial (skin),
endothelial (blood vessel) and
peripheral nerve cells

Ideally, these should be easy to culture and most popular model cell lines.

Try the ATCC.

thanks
