Intramyocardial injection of heart-derived extracellular matrix combined with cardiosphere-derived cells improves myocardial structure and function in rats with acute myocardial infarction
This study aimed to investigate the cardioprotective effects of intramyocardial injection of heart derived extracellular matrix (ECM) and cardiosphere-derived cells (CDCs) in a rat model of myocardial infarction (MI). ECM and CDCs were collected from the rat heart, and the proliferation, apoptosis and morphology of CDCs maintained on ECM were characterized in vitro. MI model was established in ...
متن کاملIntracoronary delivery of self-assembling heart-derived microtissues (cardiospheres) for prevention of adverse remodeling in a pig model of convalescent myocardial infarction.
BACKGROUND Preclinical studies in rodents and pigs indicate that the self-assembling microtissues known as cardiospheres may be more effective than dispersed cardiosphere-derived cells. However, the more desirable intracoronary route has been assumed to be unsafe for cardiosphere delivery: Cardiospheres are large (30-150 μm), raising concerns about likely microembolization. We questioned these ...
متن کاملIntramyocardial Delivery of Mesenchymal Stem Cell-Seeded Hydrogel Preserves Cardiac Function and Attenuates Ventricular Remodeling after Myocardial Infarction
BACKGROUND To improve the efficacy of bone marrow-derived mesenchymal stem cell (MSC) therapy targeted to infarcted myocardium, we investigated whether a self-setting silanized hydroxypropyl methylcellulose (Si-HPMC) hydrogel seeded with MSC (MSC+hydrogel) could preserve cardiac function and attenuate left ventricular (LV) remodeling during an 8-week follow-up study in a rat model of myocardial...
متن کاملAutologous intramyocardial injection of cultured skeletal muscle-derived stem cells in patients with non-acute myocardial infarction.
AIM Experimental animal studies suggest that the use of skeletal myoblast in patients with myocardial infarction may result in improved cardiac function. The aim of the study was to assess the feasibility and safety of this therapy in patients with myocardial infarction. METHODS AND RESULTS Twelve patients with old myocardial infarction and ischaemic coronary artery disease underwent treatmen...
متن کاملDirect Renin Inhibitor Attenuates Left Ventricular Remodeling in Post-Myocardial Infarction Heart Failure Mice.
BACKGROUND The role of direct renin inhibitors in myocardial ischemia-induced heart failure is controversial. We hypothesized that direct renin inhibitors play a positive role, affecting in vivo myocardial function as well as in vitro extracellular matrix change. METHODS Ten-week-old C57BL/6J male mice with 2-kidney 1-clip (2K1C) model were enrolled in this study. The mice were divided into 3...
