Objective To investigate the validity of selecting subclones of human breast cancer cells with high- and low-metastatic potentiality
based on their different ability of penetrating the matrigel in vitro
and analyze their biological characteristics. Methods Continuous in vitro invasion assays in matrigel were applied to screen two subclones of human breast cancer cell line MDA-MB-435s
characterized by high- and low-metastatic potentiality. Cell growth curve assay
invasion assay
adhesion assay and angiopoiesis-promoting assay were conducted to explore the different biological properties of these two subclone cells. Results Two subclones of MDA-MB-435s
of high- and low-metastatic potentiality respectively
were obtained through continuous in vitro invasion assay
manifesting significant difference in growth rate
invasion ability
adhesion ability and angiopoiesis-promoting ability. Conclusion It is feasible to obtain subclones of human breast cancer cells of high- and low-metastatic potentiality by utilizing their difference in penetrating the matrigel in vitro.
