I have tried extensively to introduce YACs into human lung cells using
spheroplast fusion and have had no luck whatsoever.  I have, on several
occassions, gotten colonies to grow out for a week or two, but these always
eventually die.  I would also love to get any information about introducing
YACs into human cells.

There are three things you don't get over in a hurry...disproving a
beautiful hypothesis, eating bad possum, and eating good possum.
