Cell line contamination, an ongoing issue

May 1, 2015

I recently published in The Scientist a commentary on the problem of contamination and mislabeling of mammalian cell lines, "Seeded by Weeds: More than 50 years after cross-contamination of cultured cell lines was recognized, the problem continues to plague the scientific community."  http://www.the-scientist.com/?articles.view/articleNo/42789/title/Seeded-by-Weeds/. As the article points out, this is an especially distressing phenomenon in view of the fact that it was documented a half century ago. Is it too much to ask that the research community take steps to eliminate this costly and embarrassing hazard to cell culture investigation?
