Current cell-based repair strategies have proven unsuccessful for treating cartilage defects and osteoarthritic lesions, consequently advances in innovative therapeutics are required and mesenchymal stem cell-based (MSC) therapies are an expanding area of investigation. MSCs are capable of differentiating into multiple cell lineages and exerting paracrine effects. Due to their easy isolation, e...

As a key molecule of the extracellular matrix, laminin provides a delicate microenvironment for cell functions. Recent findings suggest that laminins expressed by cartilage-forming cells (chondrocytes, progenitor cells and stem cells) could promote chondrogenesis. However, few papers outline the effect of laminins on providing a favorable matrix microenvironment for cartilage regeneration. In t...

Degradable scaffolds represent a promising solution for tissue engineering of damaged or degenerated articular cartilage which due to its avascular nature, is characterized by a low self-repair capacity. To estimate the articular cartilage regeneration process employing degradable scaffolds, we propose a mathematical model as the extension of Olson and Haider's work (Int. J. Pure Appl. Math. 53...

The regeneration of damaged cartilage due to injuries and diseases is a major goal for the future. Cartilage has limited healing capacity. There have been a number of studies shown to induce cartilage regeneration both in vitro and in vivo. Yet we are far from obtaining regenerated cartilage that has the properties similar to the native cartilage. Chondrogenesis of mesenchymal stem cells (MSCs)...

INTRODUCTION Transplantation of mesenchymal stem cells (MSCs) derived from synovium is a promising therapy for cartilage regeneration. For clinical application, improvement of handling operation, enhancement of chondrogenic potential, and increase of MSCs adhesion efficiency are needed to achieve a more successful cartilage regeneration with a limited number of MSCs without scaffold. The use of...

Background: Autologous periosteal grafting is used as treatment for articular cartilage defect. Objective: To study the effect of bone morphogenetic protein (BMP) on articular cartilage regeneration following periosteal grafting. Methods: 16 healthy 15-week-old New Zealand white rabbits of both sexes (32 knees) were randomly divided into experimental group (group A) and control group (group B)....

OBJECTIVE To investigate ultrasonic evaluation methods for detecting whether the repair tissue is hyaline cartilage or fibrocartilage in new cartilage regeneration therapy. METHODS We examined four experimental rabbit models: a spontaneous repair model (group S), a large cartilage defect model (group L), a periosteal graft model (group P) and a tissue-engineered cartilage regeneration model (...

hyaline cartilage is a vascular and neural tissue with scanty chondrocytes and limited regenerative ability. after some serious injuries of the cartilage, healing process will take place through the formation of fibrocartilage structures. currently, tissue engineering and cell therapy are 2 interesting therapeutic fields dealing with regenerative medicine. in this regard, tissue regeneration ha...
