IL-9 induces the survival of BMMCs through γc- and Jak3-dependent signaling.
BMMCs from WT, γc−, and Jak3−mice were cultured in the absence of IL-3 for 5 days, and cell viability was determined by FACS using PI (5 μg/mL) at days 0, 1, 3, and 5. Where indicated, recombinant murine IL-9 or recombinant human IL-15 was added at 20 ng/mL. Data are means ± SD for 5 mice in each group. *P < .05, **P < .005.
