The Preparation Methods and Types of Cell Sheets Engineering

Cell therapy has emerged as a viable approach for treating damaged organs or tissues, particularly with advancements in stem cell research and regenerative medicine. The innovative technique of cell sheet engineering offers the potential to create a cell-dense lamellar structure that preserves the extracellular matrix (ECM) secreted by cells, along with the cell-matrix and intercellular junctions formed during in vitro cultivation. In recent years, significant progress has been made in developing cell sheet engineering technology. A variety of novel materials and methods were utilized for enzyme-free cell detachment during the cell sheet formation process. The complexity of cell sheet structures increased to meet advanced usage demands. This review aims to provide an overview of the preparation methods and types of cell sheets, thereby enhancing the understanding of this rapidly evolving technology and offering a fresh perspective on the development and future application of cell sheet engineering.
