Viscoelastic Mechanics: From Pathology and Cell Fate to Tissue Regeneration Biomaterial Development

Area of Science:

• Biophysics
• Biomaterials Science
• Regenerative Medicine

Background:

• Viscoelasticity is a critical mechanical property of living tissues and the extracellular matrix (ECM).
• It acts as a crucial biophysical cue regulating cell function, tissue development, homeostasis, and disease progression.
• Dysregulation of matrix viscoelasticity is implicated in various pathological conditions.

Purpose of the Study:

• To review the relationship between matrix viscoelasticity and tissue functions in physiological and pathological states.
• To explore cell responses to ECM viscoelasticity and underlying mechanisms.
• To highlight the potential of viscoelastic biomaterials in tissue regeneration and disease treatment.

Main Methods:

• Literature review focusing on the role of matrix viscoelasticity in tissue function and disease.
• Analysis of cell responses to varying ECM viscoelasticity.
• Review of advances in viscoelastic biomaterials for tissue repair.

Main Results:

• Matrix viscoelasticity is integral to tissue development, regeneration, and homeostasis.
• Altered viscoelasticity is linked to aging, fibrosis, degenerative diseases, and cancer.
• Cellular responses to ECM viscoelasticity are complex and mechanistically driven.
• Viscoelastic biomaterials mimicking native ECM show promise for tissue repair.

Conclusions:

• Understanding matrix viscoelasticity provides insights for developing biomaterials for regenerative medicine.
• Tunable viscoelastic biomaterials that match native tissue properties are crucial for promoting tissue regeneration.
• These biomaterials offer potential therapeutic applications in degenerative diseases and organ development.
