Reversibility of the tumor cell dormancy-like phenotype. Cells were seeded on Mg and Mg–6Ag, detached and reseed on glass slides. Relative Ki-67 positive cells are shown as m±sd from two samples with three randomly chosen positions for each sample. Significance differences between relative Ki-67 positive cells on Mg or Mg–6Ag or their reseeded pairs were obtained via a Mann-Whitney test (n = 6); ** = p < 0001.
