***P = 0.0507
Cells from 2 CFC plates for each experimental condition were harvested, Giemsa-stained Cytospin smears were prepared, and 500-cell differential counts were performed. The numbers shown are averages from 3 independent experiments ± standard deviations. The P value was obtained by comparing to control using a paired two-tailed distribution t-test.
