Bone-marrow eosinopoiesis in egg white-implanted and sham-implanted mice. Data are means±s.e.m. of the percent eosinophils in cytocentrifuge smears of (a) bone-marrow cells, or (b) cells present in 7-day bone-marrow liquid cultures. NAÏVE, naïve controls, SHAM, sham-implanted, and EWI, egg white-implanted mice. Bone-marrow counts and cultures were made at the indicated times after surgery. Multiple comparisons between groups were carried out within each time point. P-values are indicated for all significant differences. In (a), numbers of experiments for the three groups were, respectively, 17, 22, and 12 at 24 h; 17, 11, and 20 at 15 days; and 17, 7, and 11 at 30 days. In (b), numbers of experiments for the three groups were, respectively, 14, 17, and 12 at 24 h; 14, 12, and 16 at 15 days; and 14, ,7 and 12 for 30 days.
