transfection of zebrafish fibroblast cell lines?

[Jill]

Hello!  I was wondering if anyone has successfully transfected any 
of the zebrafish fibroblast cell lines that are available from ATCC, or 
any other types of zebrafish cell cultures for that matter?  
Someone told me that fibroblasts are very difficult to transfect - is 
that true?  I haven't been able to find any references on transfection 
of any of the 4 fibroblast lines available at ATCC, but I thought I'd 
ask here.  Thanks in advance for any info.
