GATA2 is critical for connective tissue mast cell differentiation and
IgE/mast cell-mediated anaphylaxis. A, Flow analysis of peritoneal
cavity mast cells (MC) and bone marrow basophils (Ba). Total number of cells
(mean ± SEM, n=3 mice) (right panel). B,
Toluidine blue staining of mast cells (magnification 3×40; insert,
3×100). Mast cells are indicated by arrows. Average number of mast cells
in ten randomly selected fields (mean ± SEM, n=3 mice). C,
PCA analysis, mean ± SEM, n = 3 mice; D, PSA analysis, mean
± SEM, n = 6 mice. E, ELISA analysis of histamine, mean
± SEM, n=3 samples from 3 individual mice. F, ELISA analysis
of MMCP-1 (mean ± SEM, n=3 samples from 3 individual mice).
G, PSA analysis of the
Gata2f/fMcpt5-Cre
mice reconstituted BMMCs (mean ± SEM, n=5 mice). Statistical differences
were analyzed by student’s t test (A,
B, C, E, F) or by ANOVA
(D, G). *: p<0.05; **: p<0.01; ***:
p<0.001.
