Abstract
The variants of the B16 murine melanoma cell line were assayed for their invasive characteristics in the membrane invasion culture system (MICS) and concomitantly tested for their ability to form lung metastases in vivo. Specifically, the B16F1 (low metastatic variant) and the B16F10 (high metastatic variant) murine melanoma cell lines were examined for their ability to invade human amniotic basement membranes (BMs) in vitro and simultaneously examined for lung colony formation in vivo. The B16F1 and B16F10 cell lines both demonstrated similar invasion profiles over 72 h with the total percent invasion through the BMs for both cell lines not exceeding 5.0%. In vivo observations reconfirmed the significant difference in the metastatic capabilities of the 2 variants. These data suggest that tumor cells with differing metastatic propensities can invade an amniotic BM at similar rates, but their survival and metastatic lesion forming capabilities in vivo may vary considerably.
