摘要:: Baby hamster kidney cells were mutagenized with N-methyl-N'-nitro-N-nitrosoguanidine and selected to obtain a population of non-attaching cells. The cell variant FN-1 was cloned from the non-attaching cell population, recloned, and tested for cell adhesive interactions using four different assays of fibronectin (pFN) receptor function: cell attachment and spreading on culture dishes and cell binding and phagocytosis of latex beads. On pFN-coated culture dishes, FN-1 cells had decreased attachment compared to parental cells and were unable to spread. With pFN-coated beads, only one third as many pFN-bead binding sites could be detected on FN-1 cells as on the parental cells, and the FN-1 cells were unable to phagocytose the pFN-coated beads. In other studies, the variant cells were able to attach normally and spread partially on substrata coated with polycationic ferritin, concanavalin A, or anti-BHK cell surface antibody. The results suggest that the pFN-receptor function of FN-1 cells is defective.
