The average age group of swine flu sufferers is 12, the average age for hospitalized individuals is definitely 20, and for those who died, it had been 37.Jacobsen, M.D., Ph.D.: Persistent Malignant Stem Cells in del Myelodysplasia in Remission The concept that rare tumor stem cells might be required and adequate to propagate a malignancy is not new and has been supported by experimental evidence, first in leukemia1 and subsequently in solid tumors.2 Implicit in the cancers stem-cell model are the hypotheses that malignancy stem cells are distinct, rare populations of malignancy cells and that they could be particularly resistant to conventional cancer tumor therapies.
