since a cell type with such cytogenetical characters was also found in the primary tumor as well as in a non-metastasizing tumor variant , it is suggested that the role of the induction-selection phenomenon in the occurrence of h10z tumor metastases , i.e. , new inductor agents occurred in the tumor 's environment , might produce the induction of certain repressed mutant genes in m secondary cell type , bringing about certain phenotypical alterations ( e.g. , the decrease of the mutual cell adhesion ) which could favorize the migration and selection of this cell type .
