A Physiology-Inspired Multifactorial Toolbox in Soft-to-Hard Musculoskeletal Interface Tissue Engineering.

Area of Science:

• Biomaterials Science
• Regenerative Medicine
• Tissue Engineering

Background:

• Musculoskeletal diseases cause widespread physical disability.
• Soft and hard tissues integrate at specific interfaces crucial for movement.
• Injuries at these interfaces are difficult to regenerate due to compositional and structural gradients.

Purpose of the Study:

• To review tissue engineering strategies for soft-to-hard tissue interfaces.
• To highlight the limitations of biomaterials alone in guiding cell transplantation.
• To propose a multifactorial approach for engineering clinically relevant interfaces.

Main Methods:

• Review of current tissue engineering strategies.
• Analysis of biomaterial advancements in controlling biophysical parameters.
• Discussion on integrating biological, biophysical, and biochemical tools.

Main Results:

• Biomaterial design allows control over biophysical parameters.
• Biomaterials alone are insufficient for cell guidance and support.
• A multifactorial toolbox is necessary for effective tissue engineering.

Conclusions:

• Tissue engineering strategies are advancing for soft-to-hard tissue interfaces.
• Combining biomaterials with biological, biophysical, and biochemical tools is essential.
• This integrated approach aims to engineer clinically relevant interfaces for musculoskeletal regeneration.
