The researchers used electrohydrodynamic forces to precisely deposit bioink containing living muscle cells into organised fibre structures designed to replicate the architecture of native skeletal muscle tissue. According to the study, the technique enabled significantly greater cellular alignment compared with conventional extrusion-based bioprinting approaches. 

The engineered tissues also demonstrated improved maturation and contractile behaviour, both considered important indicators of functional muscle development. The authors noted that alignment is critical in skeletal muscle engineering, as natural muscle relies on highly ordered cellular organisation to generate coordinated contraction and force. 

The study suggests the technology could support future development of more physiologically relevant muscle models for regenerative medicine, disease modelling and drug testing. Further research will be required to assess long-term functionality, vascular integration and clinical translation.
