Skeletal muscle tissue engineering: strategies for volumetric constructs

Area of Science:

• Biomedical Engineering
• Regenerative Medicine
• Tissue Engineering

Background:

• Skeletal muscle tissue engineering faces challenges like lack of vascularization and reliable cell sources.
• Current engineered constructs often lack active function, exhibit poor cell survival, and have low metabolic capacity.
• Recent progress has led to functionally competent engineered tissues with integrated vascular structures.

Purpose of the Study:

• To review recent advancements in skeletal muscle tissue engineering.
• To highlight techniques that enhance construct functionality, vascularization, and cell survival.
• To identify promising methods transferable to other tissue engineering fields.

Main Methods:

• Review of literature on skeletal muscle tissue engineering strategies.
• Analysis of physical stimuli (mechanical, electrical) and biochemical cues.
• Examination of co-culture techniques for controlled cellular development.

Main Results:

• Engineered constructs now incorporate vascular networks to meet metabolic demands.
• Physical and electrical stimulation promote cell differentiation and construct maturation.
• Co-culture systems offer precise control over cellular development via paracrine signaling.

Conclusions:

• Functional skeletal muscle tissue engineering is advancing rapidly.
• Integration of vascular systems and advanced stimulation techniques are key.
• Promising strategies show potential for broad application across tissue engineering disciplines.
