A: representative flow cytometry scatter plots for CD45⁺, CD45⁺CD4⁺, CD45⁺CD4⁻CD11b⁺Ly6G⁺, CD45⁺CD4⁻CD11b⁺Ly6G⁻Ly6C⁺ (Ly6C^Lo and Ly6C^Hi), and CD45⁺CD4⁻CD11b⁻Ly6G⁻Ly6C⁻B220⁺ cells in the Ficoll-Paque layers and the pellets after density mediated cell separation of cardiac digests obtained from heart failure mice. B: quantitative group data from A. All the data except B220⁺ cell counts were log transformed to ensure normal distribution of data, and the transformed data for each cell type were analyzed using unpaired 2-tailed Student’s t-test. *P < 0.05, **P < 0.01, and ***P < 0.001 was considered significant (n = 5 in both groups).
