Special Issue Information

Dear Colleagues,

Recent years have seen the development of decellularized cardiac and skeletal muscles for both in vitro functional models and in vivo transplantation for tissue repair and regenerative medicine strategies. The basis of such applications relies on the ability of decellularized muscles to allow cell homing, identity, growth, and differentiation. Upon the decellularization process, the resulting biocompatible scaffold materials preserve the biological properties and composition of the native tissue.

However, it is emerging that both the type of the decellularization method and the specific pathophysiological status of the native tissue (including aging, inflammation, diseases) can strongly affect the final composition of the decellularized muscles. As such, different environments can influence both in vivo and in vitro cell behavior and remain an intriguing aspect that needs further investigation.

This Issue aims to collect the current body of scientific work related to the generation and application of decellularized cardiac and skeletal muscles as three-dimensional in vitro models and as in vivo tissue replacements.

Decellularized skeletal muscle (dSkM) constructs have received much attention in recent years due to the versatility of their applications in vitro. In search of adequate in vitro models of the skeletal muscle tissue, the dSkM offers great advantages in terms of the preservation of native-tissue complexity, including three-dimensional organization, the presence of residual signaling molecules within the construct, and their myogenic and neurotrophic abilities. Here, we attempted to develop a 3D model of neuromuscular tissue. To do so, we repopulated rat dSkM with human primary myogenic cells along with murine fibroblasts and we coupled them with organotypic rat spinal cord samples. Such culture conditions not only maintained multiple cell type viability in a long-term experimental setup, but also resulted in functionally active construct capable of contraction. In addition, we have developed a customized culture system which enabled easy access, imaging, and analysis of in vitro engineered co-cultures. This work demonstrates the ability of dSkM to support the development of a contractile 3D in vitro model of neuromuscular tissue fit for long-term experimental evaluations. Full article
