Meat palatability is the primary determinant of consumer acceptance. This attribute is in turn determined by the highly-ordered structure of the tissue’s complex cellular andmatrix components. Current strategies to reproduce these intricate features in vitrousually rely on intricate and costly setups with limited scalability potential. Recently, Professor Che Connon’s group at Newcastle University demonstrated that tissue templating represents a simple and cheap but efficient strategy to control the behavior of stromal stem cells in vitro to create highly-ordered connective tissue equivalents for regenerative medicine applications. Specifically, they showed that substrate curvature at the millimeter-scale spontaneously promote the migration, proliferation, and self-organization (alignment) of stromal cells and of their deposited matrix. Moreover, templated surfaces were able to elicit the controlled bio-fabrication of dense, highly-ordered connective tissues reproducing the 3D architecture and composition of their natural counterparts. As such, the concept of tissue templating using curved surfaces may constitute an ideal approach to produce larger, denser, and easily-recoverable structured muscle tissues with an organization and composition that allows reproducing the texture of natural meat, as recognized by the consumers’ palate (Fig. 1).
