Figure 2.

Echocardiographic evaluations revealed better-preserved hearts in the group of animals transplanted with expanded CD133⁺ cells. Comparison of left ventricular end-systolic volume (a), left ventricular end-diastolic volume (b), left ventricular end-systolic area (c), and left ventricular end-diastolic (d) within each group pretreatment and posttreatment. The results are presented as the mean (point in the box) with the standard error (stripped boxes) and standard deviation (lines). Control = control group, injected with isotonic saline solution (sodium chloride 0.9%). Purified = transplanted with purified CD133⁺ cells. Expanded = transplanted with expanded CD133⁺ cells. The p values of each comparison are shown on top of the boxes.
