Abstract (original English)

Recent clinical developments in tissue bioengineering have applications in acute cardiac ischemia and infarction and include the use of stem cells that combine injectable scaffold material. This study aimed to evaluate the effects of adipose-derived stem cells (ADSCs) that combine the Matrigel scaffold on cardiac morphology/functions. The autologous ADSCs myocardial infarction (MI) model was induced by the permanent ligation method of the left anterior descending coronary artery (LAD). MI-operated rats were randomly divided into PBS group, Matrigel group, PBS plus ADSCs group (PBS+ADSCs), and Matrigel plus ADSCs group (Matrigel+ADSCs). Matrigel was used as an injectable scaffold. Rats with a 1-week-old myocardial infarction were injected with 2 × 10 6 labeled ADSCs in the border area of the ischemic heart. Heart function was determined by echocardiography. The hemodynamics, cardiac structure, and graft characteristics were evaluated. The ADSCs were successfully isolated and identified, demonstrating a good proliferative status and cell retention in the Matrigel. ADSCs+Matrigel exhibited the most improved heart functions (LVESD, LVEDD, LVFS, LVEF) compared to those of other groups (p < 0.05). ADSCs+Matrigel significantly reduced infarct size compared to other groups (p < 0.05). Cotransplantation of ADSCs and Matrigel showed the best effect on maintaining the thickness of the ven
