Preparation and application of decellularized extracellular matrix bioink: a review / 生物工程学报

Decellularized extracellular matrix (dECM), which contains many proteins and growth factors, can provide three-dimensional scaffolds for cells and regulate cell regeneration. 3D bioprinting can print the combination of dECM and autologous cells layer by layer to construct the tissue structure of carrier cells. In this paper, the preparation methods of tissue and organ dECM bioink from different sources, including decellularization, crosslinking, and the application of dECM bioink in bioprinting are reviewed, with future applications prospected.
