This reminds me of this culture of cancer cells from a woman who died from cancer in the 50s. The cancer is still alive in laboratories today and there were even proposals to classify it as a new species:
ex-gf was working with "her" cells some 6-8 years ago while researching some rare type of anemia, back in Prague. Didn't know it's actually used worldwide.
