This study developed a novel biomimetic scaffold using decellularized meniscus extracellular matrix (dME) and synthetic nanofibers. The scaffold enhances meniscus cell function and promotes the formation of meniscus-like tissue for potential knee repair therapies.
Area of Science:
- Biomaterials Science
- Tissue Engineering
- Orthopedic Research
Background:
- The meniscus is vital for knee function but prone to injury, with limited natural repair capabilities in adults due to low cell density, dense matrix, and poor vascularity.
- Menisci are fibrocartilaginous tissues with a fibrous extracellular matrix (ECM) and a mix of chondrocyte-like and fibroblast-like cells.
Purpose of the Study:
- To develop a fibrous scaffold system incorporating decellularized meniscus ECM (dME) within a synthetic material to support and enhance meniscus cell function and matrix production.
- To create a biomimetic scaffold that mimics native meniscus morphology and composition for improved therapeutic strategies.
Main Methods:
- Electrospinning was used to create a fibrous scaffold system from poly(e-caprolactone) and decellularized meniscus ECM (dME).
- The scaffold's properties, including hydrophilicity and susceptibility to enzymatic digestion, were characterized.
- In vitro studies assessed meniscus cell spreading, proliferation, and gene expression on the scaffold.
Main Results:
- Incorporation of dME into synthetic nanofibers increased scaffold hydrophilicity.
- The dME-containing scaffold significantly enhanced meniscus cell spreading, proliferation, and fibrochondrogenic gene expression.
- The scaffold supported the secretion of collagen and proteoglycans and facilitated meniscus-like tissue formation.
Conclusions:
- A novel biomimetic scaffold combining synthetic materials with dME shows promise for meniscus tissue engineering.
- This scaffold provides appropriate signals and a suitable template for meniscus fibrochondrocytes, supporting cell growth and matrix production.
- The developed scaffold represents a potential therapeutic strategy for substituting or replacing injured meniscus tissue.
