CEC kinetics and viability in lymphoma-bearing mice. Left panels show tumor volume, day of MTD (gray arrows) and metronomic (black arrows) treatments, and CEC count in NOD/SCID mice that had been given injections of Namalwa and in cancer-free, control animals. Results are expressed as mean ± 1 SD (bars). n = 12 per study group. Right panels show tumor volume, day of MTD (gray arrows) and metronomic (black arrows) treatments, and CEC count in NOD/SCID mice that had been given injections of Granta 519. Results are expressed as mean ± 1 SD (bars). n = 12 per study group. *P < .01.
