Summary
Regenerating functional cartilage is challenging due to a lack of understanding of its structural regions and chondrocyte origins. Focusing on lamina splendens and calcified cartilage regeneration may improve long-term survival of engineered cartilage.
Area of Science:
- Biomedical Engineering
- Tissue Engineering
- Regenerative Medicine
Background:
- Articular cartilage, despite its apparent simplicity (avascular, single cell type: chondrocyte), is difficult to engineer for functional joint repair.
- Current challenges in cartilage regeneration may stem from an incomplete understanding of distinct structural regions and chondrocyte origins/maintenance.
Purpose of the Study:
- To review current knowledge on articular cartilage structural regions and stem cell populations within articulating joints.
- To emphasize the potential significance of regenerating specific cartilage regions for successful in vivo survival of engineered constructs.
Main Methods:
- Literature review of existing research on articular cartilage structure, chondrocytes, and stem cells.
- Analysis of the importance of different cartilage regions for tissue regeneration.
Main Results:
- Articular cartilage exhibits distinct structural regions with varying biological significance.
- Understanding chondrocyte origins and maintenance is crucial for effective tissue engineering.
- The lamina splendens (joint surface) and calcified cartilage (bone interface) are highlighted as critical regions for regeneration.
Conclusions:
- Successful cartilage regeneration requires a deeper appreciation of its complex regional anatomy and cellular dynamics.
- Regeneration strategies should prioritize the restoration of the lamina splendens and calcified cartilage for enhanced integration and long-term viability of engineered tissues.

01:27Growth 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...
01:19Mesenchymal Stem Cells
Mesenchymal stem cells (MSCs) are adult stem cells that can differentiate into most connective tissue cell types, except for hematopoietic cells, depending upon the source of MSCs. For example, bone-marrow-derived MSCs (BM-MSCs) can differentiate into osteocytes, hepatocytes, and pancreatic and neuronal cells. MSCs can be isolated from various sources such as bone marrow, placenta, adipose tissue, teeth, and Wharton’s jelly, a gelatinous substance in the umbilical cord. The ease of their access...
01:07Development of the Limb Synovial Joints
Joints form during embryonic development in conjunction with the formation and growth of the associated bones. The embryonic tissue that gives rise to all bones, cartilage, and connective tissues of the body is called mesenchyme.
The mesenchymal stem cells differentiate into chondrocytes that form the hyaline cartilage, and later the cartilaginous model of the bone. This model further transforms into a bone. This process is known as endochondral ossification.

01:17Stem Cell Culture
Stem cell research aims to find ways to use stem cells to regenerate and repair cellular damage. Over time, most adult cells undergo the wear and tear of aging and lose their ability to divide and repair themselves. Stem cells do not display a particular morphology or function. Adult stem cells, which exist as a small subset of cells in most tissues, keep dividing and can differentiate into a number of specialized cells generally formed by that tissue. These cells enable the body to renew and...
01:24Bone Formation by Endochondral Ossification
Bone formation, or ossification, begins around the sixth to seventh week of embryonic development. Most bones develop from a cartilaginous template through the process of endochondral ossification. Cartilage formation begins when clusters of mesenchymal cells differentiate into chondrocytes. These chondrocytes proliferate rapidly and secrete an extracellular matrix that becomes encased in a membrane called the perichondrium. The resulting cartilage model provides a template that resembles the...
01:21Stem Cell Therapy for Tissue Regeneration
Stem cell therapy is a method used in regenerative medicine to repair and restore function to damaged tissues and organs. Stem cells have the potential to proliferate and differentiate into various tissue types, making them ideal candidates for tissue regeneration. For example, hematopoietic stem cell transplants are commonly used in blood cancer treatment to replenish damaged bone marrow and restore healthy blood cells.
