mmer Bioengineering Conference, June 25-29, Sonesta Beach Resort in Key Biscayne, Florida in synovial joints is exposed to compressive normal activity. These mechanical signals are and homeostasis of the tissue. Consequently ng has been proposed within a tissue stimulation of isolated cells seeded within 3D antation. However, the mechanotransduction ch cells are able to sense and respond to thin 3D scaffolds are poorly understood. A groups have utilised a well characterised odel to examine the influence of compressive lism and the associated intracellular signalling ntrast the effect of shear strain has received ble due to the complex test rigs required [3-4]. e development and characterisation of a new the application of static or cyclic shear strain ts.

Molecular analysis of chondrocytes cultured in agarose in response to dynamic compression
BACKGROUND Articular cartilage is exposed to high mechanical loads under normal physiological conditions and articular chondrocytes regulate the composition of cartilaginous matrix, in response to mechanical signals. However, the intracellular pathways involved in mechanotransduction are still being defined. Using the well-characterized chondrocyte/agarose model system and dynamic compression, ...
متن کاملDesign and validation of an in vitro loading system for the combined application of cyclic compression and shear to 3D chondrocytes-seeded agarose constructs.
Physiological loading is essential for the maintenance of articular cartilage by regulating tissue remodelling, in the form of both catabolic and anabolic processes. To promote the development of tissue engineered cartilage which closely matches the long term functionality of native tissue, bioreactors have been developed to provide a combination of loading modalities, which reflect the nature ...

Osteoarthritis is a severe socio-economical disease, for which a suitable treatment modality does not exist. Tissue engineering of cartilage transplants is the most promising method to treat focal cartilage defects. However, current culturing procedures do not yet meet the requirements for clinical implementation. This article presents a novel bioreactor device for the functional tissue enginee...
متن کاملMechanical compression influences intracellular Ca2+ signaling in chondrocytes seeded in agarose constructs.
Ca2+ signaling forms part of a possible mechanotransduction pathway by which chondrocytes may alter their metabolism in response to mechanical loading. In this study, a well-characterized model system utilizing bovine articular chondrocytes embedded in 4% agarose constructs was used to investigate the effect of physiological mechanical compressive strain applied after 1 and 3 days in culture. T...
متن کاملThe Effect of Dynamic Shear Force on Chondrocyte Biosynthesis in Agarose Gels
The dense extracellular matrix (ECM) within the articular cartilage derives its compressive modulus from the electrostatic and osmotic interactions between highly charged glycosaminoglycan (GAG) chains. Furthermore, the structural integrity of the ECM comes from the tightly interwoven collagen network, which accounts for the tensile and shear stiffness of the cartilage. Due to the avascular, an...
