Abstract:

BACKGROUND: All-natural cardiac decellularized scaffold material has macroscopic and microstructure, matrix components and vascular network distribution similar to the receptor, which is an ideal material for heart tissue engineering.
OBJECTIVE: To summarize the preparation methods, composition characteristics, biological characteristics and the latest research progress of cardiac decellularized matrix scaffold.
METHODS: Relevant articles published from January 2008 to April 2017 were searched in PubMed and Wanfang databases using the keywords of “heart, cardiac muscle, myocardial tissue, decellularized matrix” in English and Chinese, respectively. Finally, 50 representative articles (44 in English and 6 in Chinese) were included with the exception of the articles that were associated with cardiac valves.
RESULTS AND CONCLUSION: Currently, the methods of preparing cardiac decellular matrix scaffolds include physical processing, chemical method and biological treatment (enzymatic method). Cardiac extracellular matrix scaffolds mainly contain I, III and IV collagen, glycosaminoglycans, fibronectin, laminin and a small amount of growth factors. At present, the application of the decellular matrix in myocardial tissue engineering includes three directions: the "band-aid" myocardial tissue engineering study based on decellular matrix lamella; the study of the myocardial tissue engineering on injectable myocardial tissue engineering based on the decellular matrix; and the study of decellularized-recellularized artificial cardiac reengineering based on the cardiac all-organ. Although some successful experience has been achieved in the stents, their use in the cardiac replantation still has many problems to be solved.
