Summary
Organs-on-chips offer a human-relevant alternative to animal models for studying complex neuromuscular diseases. While challenges remain, these advanced models show promise for personalized medicine and drug development.
Area of Science:
- Biomedical Engineering
- Regenerative Medicine
- Disease Modeling
Background:
- Animal models present limitations in human relevance for complex neuromuscular diseases.
- Organs-on-chips (OoCs) utilize microfabrication to create patient-specific, in vitro tissue models.
- OoCs offer a promising alternative for disease modeling and drug development due to their compatibility with patient-derived cells.
Purpose of the Study:
- To review the challenges in modeling neuromuscular diseases using animal models.
- To survey existing organ-on-chip approaches for neuromuscular tissues.
- To discuss the potential and limitations of OoCs in neuromuscular disease research.
Main Methods:
- Review of current literature on organ-on-chip technologies for neuromuscular applications.
- Survey of cell sources for muscle and nerve tissue engineering.
- Analysis of 2D and 3D neuromuscular tissue engineering techniques.
Main Results:
- Significant advancements have been made in modeling neuromuscular diseases using OoCs.
- Challenges persist in cell sourcing, maturity, tissue assembly, and readout capabilities.
- OoCs have demonstrated potential in addressing human relevance limitations of animal models.
Conclusions:
- Organ-on-chip technology is a rapidly advancing field with great potential for neuromuscular disease research.
- Despite current limitations, OoCs are valuable complementary tools to animal models for understanding disease mechanisms.
- Further development of OoCs could significantly impact patient-specific disease modeling and therapeutic strategies for neuromuscular conditions.
