Organ-on-a-chip stands as a pivotal platform for skeletal muscle research while constructing 3D skeletal muscle tissues that possess both macroscopic and microscopic structures remains a considerable challenge. This study draws inspiration from LEGO-like assembly, employing a modular approach to construct muscle tissue that integrates biomimetic macroscopic and microscopic structures. Modular LEGO-like hybrid nanofibrous scaffold bricks were fabricated by the combination of 3D printing and electrospinning techniques. Skeletal muscle cells cultured on these modular scaffold bricks exhibited a highly orientated nanofibrous structure. A variety of construction of skeletal muscle tissues further enabled development by various assembling processes. Moreover, skeletal muscle-on-a-chip (SMoC)…

Organ-on-a-chip (OOC) is now becoming a potential alternative to the classical preclinical animal models, which reconstitutes in vitro the basic function of specific human tissues/organs and dynamically simulates physiological or pathological activities in tissue and organ level. Despite of the much progress achieved so far, there is still an urgent need to explore new biomaterials to construct a reliable and efficient tissue–tissue interface and a general fabrication strategy to expand from single-organ OOC to multi-organ OOC in an easy manner. In this paper, we propose a novel strategy to prepare double-compartment organ-on-a-chip (DC-OOC) using electrospun poly(l-lactic acid)/collagen I (PLLA/Col I)…
