Figure 2. FcεR1α+ GMPs Possess the Ability to Express IL-4, IL-6, and IL-13.
(A) The gates for sorting FcεR1α− and FcεR1α+ GMPs. The sorted FcεR1α− and FcεR1α+ GMPs were stained with May-Grunwald Giemsa. (B) The sorted cells were stimulated with P&I for 4 hours. mRNA expression was measured by qPCR (mean ± SD, triplicates). Ba=basophils; MC=BMMC. (C) The sorted FcεR1α− and FcεR1α+ GMPs were not cross-linked (NCL) with IgE, cross-linked with IgE (IgECL) or stimulated with P&I for 4 hours. (D) The sorted cells were stimulated with P&I overnight. IL-4, IL-6, and IL-13 proteins were measured by ELISA (mean ± SD, triplicates). Data represent two independent experiments with similar results.
