Application of biomaterials in cardiac tissue engineering: Current status and prospects

Abstract

Cardiovascular diseases have become one of the leading causes of death and illness worldwide, posing significant challenges to global health. Due to the limited regenerative capacity of the heart, conventional approaches to treating heart diseases have demonstrated limited effectiveness. Therefore, leveraging biomaterials and biotechnologies in cardiac tissue engineering has emerged as a promising therapeutic strategy. This review aims to summarize the various characteristics of biomaterials in cardiac tissue engineering and their significance in addressing heart diseases. We categorize biomaterials into natural, synthetic, and conductive types based on their sources and unique properties, focusing on their applications in cardiac tissue engineering. We then present current applications of biomaterials in cardiac tissue engineering, followed by a discussion of existing challenges such as long-term material stability, biocompatibility, adverse reactions, and precise application methodologies. Additionally, we provide insights into potential strategies for overcoming these challenges, aiming to enhance the effectiveness and safety of biomaterials in cardiac tissue engineering applications. Finally, this review highlights the potential of emerging biomaterials and technologies, underscoring the critical role of interdisciplinary collaboration in driving innovation and progress in cardiac tissue engineering.
