Figure 3. Effect of intramyocardial co-injection of a fibrin scaffold on cardiac cell retention post-myocardial infarction.

^99mTc-labeled BMC were injected post-myocardial infarction directly into the myocardium in vehicle (DMEM, N = 22) or in a fibrin scaffold (Fibrin, N = 15). Cell retention was assessed 24 hours later by the level of radioactivity in the heart shown as percentage means (±SE). * denotes statistical significance for P<0.01.
