“One hotly debated question is whether metastatic cells share characteristics of stem cells, and if so, to what extent. Some studies have found cancer cells with stem-cell markers, others have displayed stem-cell-like behavior, and yet others have suggested that cells can spontaneously switch from a primary cancer cell to a stem-cell-like cancer cell and back.”
That sort of reminds me of the old alt medicine idea that cancer cells share characteristics with pregnancy trophoblasts and aren’t solely due to mutations.
