Figure 1: Influence of donor age on BMC therapeutic potential for treatment of recipient MI. Implanted BMCs were harvested from donor mice at ages of young, middleaged and old. HBSS served as a negative control. (A) Recipient left ventricular ejection fraction (EF) at baseline, day 2 post-MI and day 28 post-MI. (B) Recipient left ventricular end-systolic volume (ESV). (C) Recipient end-diastolic volume (EDV). (D) Recipient anterior wall thickness at border zone and infarct area. (E) Recipient infarct size at day 29 post-MI, expressed as a rough percentage of the left ventricle that is occupied by infarct scar.
