Mohammadi, M. H., Obregón, R., Ahadian, S., Ramón-Azcón, J., Radisic, M., (2017). Engineered muscle tissues for disease modeling and drug screening applications Current Pharmaceutical Design 23, (20), 2991-3004

Animal models have been the main resources for drug discovery and prediction of drugs’ pharmacokinetic responses in the body. However, noticeable drawbacks associated with animal models include high cost, low reproducibility, low physiological similarity to humans, and ethical problems. Engineered tissue models have recently emerged as an alternative or substitute for animal models in drug discovery and testing and disease modeling. In this review, we focus on skeletal muscle and cardiac muscle tissues by first describing their characterization and physiology. Major fabrication technologies (i.e., electrospinning, bioprinting, dielectrophoresis, textile technology, and microfluidics) to make functional muscle tissues are then described. Finally, currently used muscle tissue models in drug screening are reviewed and discussed.

Tissue engineering (TE) aims to restore function or replace damaged tissue through biological principles and engineering. Nanofibers are attractive substrates for tissue regeneration applications because they structurally mimic the native extracellular matrix. Composite nanofibers, which are hybrid nanofibers blended from natural and synthetic polymers, represent a major advancement in TE and regenerative medicine, since they take advantage of the physical properties of the synthetic polymer and the bioactivity of the natural polymer while minimizing the disadvantages of both. Although various nanofibrous matrices have been applied to almost all the areas of TE, in this chapter we will focus on nanofiber composites scaffolds for vascular TE.
