    It's nice this has been so well documented. It's a common problem with cell cultures of mammalian origin too. I was recently at a conference where several people all using the "same" cell line (from the same original source) were discussing issues of problems replicating findings across different labs. As they were discussing the characteristics of the cell line, it dawned on them that they no longer have the same cell line. It has independently mutated in each of the labs to display different characteristics. It's something people working with cell cultures need to be aware of and need to check every so often to make sure that what they are studying hasn't changed to something they didn't intend to be studying.
