Depends on the culture...

for example fibroblasts or glial cells will stick like glue to any
non-coated tissue culture dish. However, neurons are pretty sensitive. For
example the neurons I use will only stick to poly-D-lysine coated Nunc
Culture dishes...!!! They will not stick to poly-D-lysine coated falcon
dishes (they do - but come away in sheets after 7 DIC).

If your cells stick without poly-D-lysine, then save yourself some bucks!
Otherwise try poly-D-lysine...a cheaper alternative is to use
rat-tail-collagen...pretty easy to make yourself from tails of dead rats!
