Effect of Spi-B on development of NK cells in an FTOC with IL-15.
The conditions of the FTOC were the same as indicated in Figure 4except that IL-15, 10 ng/mL, was added to the FTOC. (A) The cell-surface antigen expression of the cells harvested from the FTOC. (B) The absolute numbers of output cells of each subpopulation per 1000 input progenitor cells calculated as indicated in Figure 4B.
