Functional enhancement of acute infracted heart by coinjection of autologous adipose-derived stem cells with matrigel

Recent clinical developments in tissue bioengineering have applications acute cardiac ischemia and infarction include the use of stem cells that combine injectable scaffold material. This study aimed to evaluate effects adipose-derived (ADSCs) Matrigel on morphology/functions. The autologous ADSCs myocardial (MI) model was induced by permanent ligation method left anterior descending coronary artery (LAD). MI-operated rats were randomly divided into PBS group, plus group (PBS+ADSCs), (Matrigel+ADSCs). used as an scaffold. Rats with a 1-week-old injected 2 × 106 labeled border area ischemic heart. Heart function determined echocardiography. hemodynamics, structure, graft characteristics evaluated. successfully isolated identified, demonstrating good proliferative status cell retention Matrigel. ADSCs+Matrigel exhibited most improved heart functions (LVESD, LVEDD, LVFS, LVEF) compared those other groups (p < 0.05). significantly reduced infarct size Cotransplantation showed best effect maintaining thickness ventricular wall Engrafted played role formation neovasculature infarction. triggered greatest enhancement arteriole density than Cotransplanting higher levels troponin T (cTnT), NK2-transcription factor related locus-5 (Nkx2.5), von Willebrand (vWF) In conclusion, this demonstrated cotransplanting resulted morphology rat
