Bone Structure

Bone Structure

Within the skeletal system, the structure of a bone, or osseous tissue, can be exemplified in a long bone, like the femur, where there are two types of osseous tissue: cortical and cancellous.

Spindle Assembly

Spindle Assembly

Spindle assembly occurs through three, often coexisting, pathways – the centrosome-mediated pathway, the chromatin-mediated pathway, and the microtubule-mediated pathway – collectively contributing to form a robust spindle apparatus.
In most cells, centrosomes are the primary microtubule nucleation centers. In the centrosome-mediated pathway, the G2-prophase transition triggers centrosome maturation and increased microtubule nucleation. Progressive nucleation results in a microtubule array...

Bone as Supporting Connective Tissue

Bone as Supporting Connective Tissue

Bone tissue forms the internal skeleton of vertebrate animals, providing structure to the body.
Bone Matrix
Bone, or osseous tissue, is a connective tissue that has a large amount of two different types of matrix material. The organic matrix is similar to the matrix material found in other connective tissues, including some amount of collagen and elastic fibers. This gives strength and flexibility to the tissue. The inorganic matrix consists of mineral salts— mostly calcium salts— that give the...

Spongy Bone

Spongy Bone

All bones comprise an outer layer of compact bone, and an interior made up of spongy bone tissue, also called cancellous or trabecular bone. In long bones, spongy bone tissue is mainly found in the interior of the epiphyses (broad ends of the bone).
Spongy bone is more porous, and less dense compared to compact bone. It is composed of concentric lamellae that are arranged irregularly to form the trabecular network. In some bones, the spaces between trabeculae contain red marrow, where...

Background:

Osteochondral damage from trauma, tumors, or degenerative diseases poses a significant clinical challenge due to limited natural tissue repair.
Current treatments for osteochondral defects often lead to substantial patient trauma and variable clinical results.
Advances in bone and cartilage tissue engineering offer innovative therapeutic strategies for osteochondral defect repair.

Purpose of the Study:

To review the selection and design of advanced scaffold materials for osteochondral regeneration.
To highlight key fabrication techniques and their impact on scaffold properties.
To discuss the potential of multiphasic scaffolds in mimicking native tissue architecture for enhanced regeneration.

Main Methods:

Review of natural (collagen, chitosan) and synthetic (polylactic acid) materials for scaffold fabrication.
Inclusion of inorganic components like bioactive glass and nano-hydroxyapatite (nHAp) in scaffold design.
Analysis of fabrication techniques including freeze-drying, electrospinning, and 3D printing for optimizing scaffold characteristics.

Main Results:

Scaffolds incorporating diverse biomaterials and fabricated using advanced techniques demonstrate improved porosity and mechanical integrity.
Multiphasic scaffold designs effectively mimic the native osteochondral tissue structure, enhancing cell interactions.
Optimized scaffolds support both cartilage and subchondral bone regeneration, addressing the complexity of osteochondral defects.

Conclusions:

Scaffold-based tissue engineering presents a viable and promising approach for treating osteochondral damage.
Tailored material selection, advanced fabrication, and multiphasic designs are crucial for successful osteochondral regeneration.
Further research into overcoming current obstacles is essential for advancing clinical applications in osteochondral repair.
