Bacterial nanocellulose: biosynthesis, structural properties and vascular tissue engineering applications.

Area of Science:

• Biomaterials Science
• Cardiovascular Tissue Engineering
• Regenerative Medicine

Background:

• Autologous vein and artery grafts are the gold standard for coronary artery bypass grafting (CABG), but have limitations.
• Limitations include vein availability and suitability, especially in older patients or those requiring reoperation.
• There is a need for biocompatible alternative materials for cardiovascular grafts.

Purpose of the Study:

• To review methods for controlling bacterial nanocellulose (BNC) production.
• To optimize the mechanical and physicochemical properties of BNC for cardiovascular tissue engineering applications.
• To explore BNC as a promising alternative graft material.

Main Methods:

• Review of literature on bacterial nanocellulose (BNC) production and modification.
• Analysis of BNC's physicochemical and mechanical properties.
• Assessment of BNC's potential for endothelial cell adhesion and integration.

Main Results:

• BNC possesses excellent biocompatibility, mechanical strength, and non-toxicity.
• Current BNC formulations face challenges with endothelial cell adhesion and mimicking native vessel properties.
• Controlled production methods can enhance BNC's surface and mechanical characteristics.

Conclusions:

• Bacterial nanocellulose (BNC) is a viable candidate for cardiovascular tissue engineering.
• Further research into controlled BNC production is essential to overcome current limitations.
• Optimized BNC grafts could offer a superior alternative to autologous materials in CABG.
