Figure 5: Immunohistofluorescent staining (a)–(f) for quantification of CD68+ cells in myocardium in the AMI area of the control (a), AMI area of the tac-treated (b), peri-AMI area of the control (c), peri-AMI area of the tac-treated (d), and normal groups (e). Note the significantly lower percentages of CD68+ cells (macrophages) in normal than in the controls and tac-treated minipigs (∗ versus other groups, all ), and significantly higher percentages of CD68+ cells in the controls than in the tac-treated minipigs († versus ‡, versus , all ) (f). Scale bars in right lower corner represent 20  m.
