Adaptive Hyaluronic Acid Hydrogels for Regenerative Wound Healing: From Microenvironment Sensing to ECM Reprogramming...

Area of Science:

• Biomaterials Science
• Regenerative Medicine
• Tissue Engineering

Background:

• Impaired wound healing involves oxidative stress, enzyme imbalance, and extracellular matrix (ECM) degradation.
• Conventional dressings fail to adequately address these complex healing challenges.
• Hyaluronic acid (HA) hydrogels show promise due to inherent bioactivity and tunable structures.

Purpose of the Study:

• To review recent advancements in stimulus-responsive HA hydrogels for wound healing.
• To highlight how HA hydrogels translate stimuli (pH, ROS, enzymes, mechanical) into therapeutic actions.
• To provide a design-oriented perspective for next-generation regenerative medicine materials.

Main Methods:

• Review of literature on stimulus-responsive HA hydrogels.
• Analysis of structure-function relationships in hydrogel design.
• Exploration of hydrogel orchestration of cellular behavior and ECM remodeling.

Main Results:

• pH-responsive, ROS-responsive, and MMP-sensitive HA hydrogels demonstrate precise control over inflammation, angiogenesis, and repair.
• These adaptive hydrogels dynamically regulate biochemical signaling and matrix mechanics.
• Emerging strategies like spatiotemporal control and AI-assisted design enhance predictability and translation.

Conclusions:

• Stimulus-responsive HA hydrogels represent a significant advancement in regenerative medicine for wound healing.
• Tailoring hydrogel responsiveness to specific wound microenvironments enables precise therapeutic delivery and tissue regeneration.
• Further development focusing on multi-signal integration and AI-driven design will accelerate clinical translation.
