Cancer stem cells markers represented by CD133 expression were present in a broad range from 0.0% to 46.0% with a median value of 0.5%; CD44 from 20.0% to 100.0% (median value 91.0%); and cells with CD24 expression were present from 0.0% to 16.0% (median value 7.0%). This evidence concerns the gene PROM1 and cancer.
