Why are nanofibers used in tissue engineering and regenerative medicine?

Nanofibers are extensively employed in tissue engineering and regenerative medicine due to their unique properties that (among others) mimic the extracellular matrix (ECM) and provide a suitable scaffold for cell growth and tissue regeneration. Their versatility and ability to mimic the ECM make nanofibers a valuable tool in the development of advanced therapies and treatments for various medical conditions and tissue defects.

Mimicking Extracellular Matrix (ECM)

Nanofibers used in tissue engineering - Mimicking extracellular matrix

Nanofibers can be designed to closely mimic the structure and composition of the natural ECM, providing a favorable environment for cell adhesion, growth, and tissue regeneration. Their nanoscale dimensions and fibrous structure resemble the native ECM, facilitating cell attachment, migration, and proliferation.

High Surface Area and Porosity

Nanofiber in tissue engineering - High surface area and porosity

Nanofibers have a large surface area and porosity, allowing for increased cell-material interactions and nutrient exchange. This property promotes cell adhesion, proliferation, and differentiation, supporting tissue growth and regeneration.

Controlled Biodegradability

Nanofiber in tissue engineering - Controlled biodegradability

Nanofibers can be engineered with tunable biodegradability, allowing them to degrade at a controlled rate. This property ensures that nanofibers provide temporary structural support during tissue regeneration while gradually degrading to make way for new tissue formation.

Drug and Growth Factor Delivery

Nanofiber tissue engineering - Drug and growth factor delivery

Nanofibers can serve as drug or growth factor delivery platforms, enabling localized and controlled release. Their high surface area and capacity for encapsulating therapeutic agents facilitate sustained and targeted delivery, enhancing the efficiency of tissue regeneration and healing.

Mechanical Strength and Flexibility

Electrospun Nanofiber applications in tissue engineering - Mechanical Strength and Flexibility

Nanofibers can be engineered to possess appropriate mechanical properties, such as tensile strength and flexibility, resembling those of native tissues. This property ensures that nanofiber scaffolds provide mechanical support to cells during tissue regeneration and can withstand physiological forces.

Electrical Conductivity

Electrospun Nanofiber applications in tissue engineering - Electrical conductivity

Nanofibers can be manufactured with additives to exhibit electrical conductivity, allowing for electrical stimulation of cells and tissues. This property can enhance cell differentiation, attachment, migration, and tissue regeneration processes, promoting more efficient tissue engineering outcomes.

Antibacterial Properties

Electrospun Nanofiber applications in tissue engineering - Antibacterial properties

Certain nanofibers can be functionalized with antibacterial agents or possess inherent antimicrobial properties. This property helps prevent infections during tissue regeneration, enhancing the overall efficiency and success of tissue engineering and regenerative medicine approaches.

Three-Dimensional (3D) Architecture

Electrospun Nanofiber applications in tissue engineering - 3D structure

Nanofibers can be assembled into 3D scaffolds, resembling the complex structure of native tissues. This 3D architecture provides a suitable environment for cell growth and tissue regeneration, facilitating efficient cell-cell interactions and tissue organization.
