Lineage negative Car1+ or lineage negative Car1- cells were sort-purified from the bone marrow of mice and seeded into MethoCult with hematopoietic cytokines. The percentages of (A,B) mast cells (MCs) and (C,D) erythrocytes were evaluated by flow cytometric analysis post-culture. (E), The number of macrophages (macs), erythrocytes (eryth), neutrophils (neu), MCs, and basophils (basos) were determined post-culture. Car1-GFP+ or Car1-GFP- cells were sort-purified from the spleens of mice and seeded into MethoCult. The percentage of (F) MCs and (G) erthrocytes were evaluated by flow cytometric analysis post-culture. (H), The number of macs, eryth, neu, MCs, and basos were determined post-culture. (I), Hemoglobin (Hb) levels were quantified on days 4 and 7 post-Trichinella infection. (J), Serum levels of mast cell protease 1 (Mcpt1) were quantified on days 4 and 7 post-Trichinella spiralis (Ts) infection. (A-J), Representative of at least 3 separate experiments. (E,H), Illustrate data pooled from 2 separate experiments.
