摘要：Decellularized plant scaffolds have been used to develop edible scaffolds for cell cultured meat because of their natural structures similar to that of mammalian tissues. However, their diverse three-dimensional (3D) porous structures may lead to differences in myogenic differentiation of skeletal muscle cells. In this study, parsley plant tissues were decellularized and modified by type A gelatin and transglutaminase while retaining, respectively, longitudinal fibrous and transverse honeycomb pore structures. The effects of the structure of the decellularized parsley scaffold on the proliferation and myogenic differentiation of C2C12 cells were investigated and the quality of cell cultured meat was evaluated. The results showed that fibrous pore structure guided cells to be arranged in parallel, whereas honeycomb pore structure connected cells in a circular pattern. After induced differentiation, the fibrous scaffolds were more inclined to form multinucleated myotubes with higher expression of myogenic genes and proteins, and the final cell-based meat contained higher total protein content. Decellularized plant scaffolds with fibrous pore structure were more suitable for myogenic differentiation of C2C12 cells, providing support to the development of edible scaffolds for cultured meat.Practical ApplicationThis study investigated the different three-dimensional (3D) pore structure of parsley parenchyma to gain insight into how the 3D pore structure of decellularized plant scaffolds regulates myogenic differentiation, which is expected to address the unstable myogenic differentiation of skeletal muscle cells on decellularized plant scaffolds in cell culture meat production.
