  • a NMRI(nu/nu) mice (six per group) with a mean body weight of 20 g were given subcutaneous injections of 106 cells and monitored for tumor formation for 56 days. At this time, the animals were killed.

  • b Day postinfection when palpable tumors were first detected.

  • c Calculated 26 days after inoculation as the product of two perpendicular diameters, one measured across the greatest width of the tumor.

  • d Measured 56 days after inoculation.
