Differences in transferrin response and numbers of transferrin receptors in rat and human mammary carcinoma lines of different metastatic potentials.


We previously found that transferrin (Tf) differentially stimulated the growth of highly metastatic variant lines of murine melanoma and that these highly metastatic cells also had greater numbers of Tf receptors on their cell surfaces. In the present study we found that highly metastatic rat mammary adenocarcinoma cell lines also responded differentially… (More)
