cell aggregation? - (Jun/25/2010 )

I have been working on a stable LNCaP cell line. Recently I noticed cells appear to aggregate on the plate.

Attached picture 1 is the cell line with normal look. picture 2 is the cell line that has the "aggregation look".

What does this kind of phenotype suggest?

Thanks!

I ran into this same problem working with LNCaP cells. Did you ever figure out why this happens and how to prevent it in the future?
