Extracellular matrix grafts: From preparation to application (Review)

Area of Science:

• Biomaterials Science
• Regenerative Medicine
• Tissue Engineering

Background:

• Traumatic soft tissue injuries pose significant clinical challenges.
• Current surgical interventions often yield unsatisfactory outcomes.
• Novel regenerative approaches are needed for effective tissue repair.

Purpose of the Study:

• To review decellularized extracellular matrix grafts (ECM-G) for tissue engineering.
• To summarize ECM-G characteristics and decellularization methods.
• To analyze the impact of bioactive factors and residual cells on ECM-G function and host response.

Main Methods:

• Review of decellularization techniques (physical and chemical) for various tissues.
• Analysis of ECM-G properties, including biomechanical and biochemical conditions.
• Evaluation of in vitro cell seeding and in vivo implantation studies.

Main Results:

• Decellularization methods aim to remove cellular antigens while preserving ECM integrity.
• ECM-G can provide a conducive environment for cell behavior and tissue remodeling.
• Bioactive factors and residual cellular components influence biological function and host response.

Conclusions:

• Decellularized matrix grafts (ECM-G) are a viable alternative for tissue engineering and regenerative medicine.
• Understanding decellularization methods and their impact is crucial for optimizing ECM-G.
• ECM-G show potential for facilitating in vivo tissue repair and remodeling.
