Growth of Cartilage and Bone Tissue

Growth of Cartilage and Bone Tissue

Chondrocytes form a temporary cartilaginous model by dividing and secreting a thick gel-like extracellular matrix. Once the chondrocytes undergo programmed cell death, osteoblasts enter the site of the cartilaginous model. The process of replacing the temporary cartilaginous model with bone in an ordered manner is called endochondral ossification. In endochondral ossification, not all of the cartilage is replaced by bone tissue. Some cartilage that performs a protective and supportive function...

Background:

Osteochondral tissue engineering aims to repair defects in cartilage and underlying bone.
Stratified scaffolds are designed to mimic the distinct layers of osteochondral tissue: cartilage, transitional zone, and subchondral bone.
Utilizing specific biomaterials for each layer is crucial for successful tissue regeneration.

Purpose of the Study:

To review current biomaterials and fabrication methods for stratified multilayered scaffolds in osteochondral tissue engineering.
To present cell seeding techniques used for characterizing these advanced scaffolds.
To highlight the potential of stratified scaffolds in mimicking the native osteochondral interface.

Main Methods:

Literature review of biomaterials used in stratified scaffold fabrication.
Analysis of various fabrication techniques (e.g., 3D printing, electrospinning, layer-by-layer assembly).
Examination of cell seeding strategies and characterization methods for multilayered constructs.

Main Results:

Diverse biomaterials, including polymers, ceramics, and hydrogels, are employed for different layers.
Fabrication methods are tailored to achieve specific structural and mechanical properties for each tissue layer.
Cell seeding techniques vary depending on the scaffold architecture and desired cell distribution.

Conclusions:

Stratified scaffolds represent a sophisticated strategy for osteochondral regeneration.
The choice of biomaterials and fabrication methods significantly impacts scaffold performance.
Further research into cell-matrix interactions and vascularization is essential for clinical translation.
