Prolonged survival of CNL neutrophils.

Neutrophils were prepared from 1 patient with CNL, 3 patients with CML, and 3 healthy volunteers. After cultivation for the indicated periods, apoptotic cells were determined by flow cytometry. The data for CML and normal neutrophils are expressed as means ± standard deviations of 3 experiments, and the data for CNL neutrophils are expressed as means of a single experiment.
