Abstract:
BACKGROUND: Insufficiency of donor heart and ethics are the major obstacles to heart transplantation. Theoretically, a tissue-engineered heart is an important means to solve the donor heart insufficiency. OBJECTIVE: To review the scaffold materials, seed cells and cell incubation methods in the construction of tissue-engineered heart, thus providing references for the future study on the tissue-engineered heart.METHODS: A retrieval of PubMed and Web of Science databases was performed for the articles addressing the construction of tissue-engineered heart from 2004 to 2016. Totally 2 921 articles were searched, and finally 53 eligible articles were included in accordance with the inclusion and exclusion criteria. RESULTS AND CONCLUSION:In vitro organ culture and the function of tissue-engineered heart are the difficulties in the construction of tissue-engineered heart.In vitro construction of tissue-engineered heart requires the supply of nutrients,gases,temperature and corresponding electrical stimulation. Myocardial cells, scaffold materials and organ culture system are indispensable for the tissue-engineered heart construction. Therefore, it is highly important to optimize the decellular process, select an ideal seed cell and improve its adhesion, proliferation and differentiation, improve the electrophysiological properties of the tissue-engineered heart by gene regulation, and confirm the long-term safety of the tissue-engineered heart.
