Only a few clones emerged from the crisis: PNT1A (Cussenot et al: J Urol 143: 881-886, 1991), PNT1B and PNT2 epithelial cell lines. Successful immortalisation was achieved only with SV40 expressing both large T and small t oncogenes, while attempts to immortalise with a vector expressing SV40 large T alone have given a few strains showing no extended lifespan and no cells which overcame the crisis.
