Abstract excerpt
Clonal lines of immortal Syrian hamster cells were previously isolated that either suppressed (supB+) tumorigenicity in hybrids with a malignant hamster cell line (BP6T) or had lost this suppression ability (supB-). Neither line was tumorigenic or showed anchorage-independent growth in normal growth medium. SupB- cells, but not supB+ cells, grew in agar supplemented with the growth factors EGF, PDGF and insulin...
