Hi there,

 I'm new to the whole virus studying world and I'm working on a line of cells that are new to me, MDCK cells. Is it true that if they become over confluent they start to transform?

I've been having a hard time finding images of transformed vs non-transformed MDCK cells.

The post-doc in my lab has told me that my cells have changed (and I've thrown away and regrew cells twice already) but they still look similar to when I first seeded them (in my opinion), the only difference I see is that they are confluent. Not that I don't trust the post-doc, but I'd just like a second opinion and if possible if people have images of the differences so I can compare between the two. What does a normal MDCK cell look like vs a transformed one. (what are key features that I should look for to tell the difference?)

I looked online and found some journals and those images looks similar to my cells that the post-doc said was transformed so I'm really confused right now. I probably learn in a different way than they do so it is probably fustrating for them to teach me. Any help would be greatly appreciated! Thanks so much!

I've attached the image from a journal that is MDCK cells and should be normal/not transformed (right?) 

Thanks!

I'm not sure what your advice is on how transformed cells are supposed to look in comparison to normal. We use MDCK and passage weekly. The only problem with being over confluent is that the assay you are using may not work so well, and when overconfluent they tend to die off. Being 100% confluent will not effect the cells, but leaving them too long may do it. Transformation would happen (I expect) only when cells are passaged many times or are infected with other cell lines.
P.S. I can't see your images,
