Description
A lung cancer cell model of invasive transformation was developed to select progressively invasive cell populations from a parental cell line of human lung adenocarcinoma, CL1. Five progressive sub-clones namely, CL1-1, CL1-2, CL1-3 CL1-4, and CL1-5 were selected using transwell and displayed increasing invasion potential (Chu et al, 1997).
