Hemopoietic progenitor cells in double mutant mice.
The means ± SD of the total number of colonies that developed in semisolid agar cultures of 2.5 × 104 femoral bone marrow cells or 105 spleen cells is shown. Cells were stimulated with the combination of IL-3, SCF, and EPO. *P < .05 for comparison of LIF-/-, IL-6-/-, or IL-11Rα-/- with wild type (wt) or of LIF-/-mpl-/-, IL-6-/-mpl-/-, or IL-11Rα-/-mpl-/-withmpl-/-. No other statistically significant differences were observed.
