Delivery of Agents Into Articular Cartilage With Electric Spark-Induced Sound Waves

Study of Differentiation Potential of the Dedifferentiated Chondrocytes From Rat Articular Cartilage into Skeletal Cell Lineages

Purpose: Dedifferentiation of the chondrocyte from rat articular cartilage with multiple subcultures and study of the redifferentiation potential of the cells into bone, cartilage and fat cell lineages. Materials and Methods: In this experimental study, chondrocytes from rat articular cartilage were isolated and expanded through several successive subcultures during which the expression levels ...

Feasibility of MHz High-Intensity Focused Ultrasound (HIFU) to Deliver Agents Locally into Articular Cartilage

Magnetic Targeted Delivery of Induced Pluripotent Stem Cells Promotes Articular Cartilage Repair

Cartilage regeneration treatments using stem cells are associated with problems due to the cell source and the difficulty of delivering the cells to the cartilage defect. We consider labeled induced pluripotent stem (iPS) cells to be an ideal source of cells for tissue regeneration, and if iPS cells could be delivered only into cartilage defects, it would be possible to repair articular cartila...

Hydrogel-Based Controlled Delivery Systems for Articular Cartilage Repair

Delivery of bioactive factors is a very valuable strategy for articular cartilage repair. Nevertheless, the direct supply of such biomolecules is limited by several factors including rapid degradation, the need for supraphysiological doses, the occurrence of immune and inflammatory responses, and the possibility of dissemination to nontarget sites that may impair their therapeutic action and ra...

Articular cartilage and changes in Arthritis: Collagen of articular cartilage

The extracellular framework and two-thirds of the dry mass of adult articular cartilage are polymeric collagen. Type II collagen is the principal molecular component in mammals, but collagens III, VI, IX, X, XI, XII and XIV all contribute to the mature matrix. In developing cartilage, the core fibrillar network is a cross-linked copolymer of collagens II, IX and XI. The functions of collagens I...
