Figure 1: Deletion of Flk2 and/or IL7Rɑ differentially affects numbers of both lymphoid and myeloid cells in the lungs of adult mice.
Cellularity was calculated by the total numbers of cells collected and dividing by the weight of the tissue. Dots represent individual mice. Black bars represent the average. *P<0.05, **P<0.005, ***P<0.001.
A, B lymphocytes were significantly reduced in Il7Rα−/− and FIDKO, but not Flk2−/−, lungs. Quantification of lymphocytes (Live, Ter119-Mac1-Gr1-CD19+) per gram of tissue in the lungs of wild type (WT) (black), Flk2−/− (gray), IL7Rα−/− (white), or FIDKO (red) adult mouse lungs. WT n=8, Flk2−/− n=8, IL7R−/− n=8, and FIDKO n=5 representing four independent experiments.
B, Neutrophils were not affected by loss of Flk2 or IL7Rα. Quantification of neutrophils (Live, CD3-CD4-CD5-CD8-B220-Ter119-CD45+Ly6g+CD11b+) per gram of tissue in the lungs of wild type (WT) (black), Flk2−/− (gray), IL7Rα−/− (white), or FIDKO (red) adult mouse lungs. WT n=8, Flk2−/− n=7, IL7R−/− n=8, and FIDKO n=6 representing four independent experiments.
C, Eosinophils were significantly reduced in Flk2−/−, IL7Rα−/−, and FIDKO mouse lungs. Quantification of eosinophils (Live,CD3-CD4-CD5-CD8-B220-Ter119-CD45+Ly6g-CD11b+SiglecFmidCD11c-) per gram of tissue in the lungs of wild type (WT) (black), Flk2−/− (gray), IL7Rα−/− (white), or Flk2−/−IL7Rα−/− (FIDKO) (red) adult mouse lungs. WT n=6, Flk2−/− n=5, IL7R−/− n=5, and FIDKO n=5 representing four independent experiments.
