Expanded CD133+ Cells from Human Umbilical Cord Blood Improved Heart Function in Rats after Severe Myocardial Infarction

Figure 3

The ejection fraction of the animals with AMI significantly increased after transplantation with expanded CD133+ cells. Comparison of the left ventricle ejection fraction within each group (a) and among the groups before (b) and after transplantation (c). 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 value is shown for each comparison.
