Comparison of the growth properties of PA-1 9113 ras-transformed cells stably transfected with the vector control (zeo-1 or zeo-2) or the PC4 expression vector (PC4-1, PC4-2, or PC4-4).
Averages of counts from duplicate dishes. Cells (105) were seeded in duplicate in 60-mm-diameter culture dishes, trypsinized after 8 days of growth, and counted with the aid of a hemocytometer.
Cells (104) were seeded in 0.35% agarose in complete medium (modified Eagle’s medium with 10% fetal bovine serum) and overlaid on a bed of 0.7% agarose in complete medium. The numbers of colonies were determined after 14 days.
