Extracellular Matrix Delays Articular Chondrocyte Dedifferentiation and Enhances Redifferentiation
Introduction Articular cartilage is a highly specialized tissue that is vulnerable to injury and disease and has a limited capacity for self-regeneration. The autologous chondrocyte transplantation technique has not been successful because of rapid dedifferentiation of chondrocytes in monolayer culture, producing fibroblast-specific markers (mainly collagen I) rather than a cartilage-specific m...
متن کاملInfluence of ivabradine on reverse remodelling during mechanical unloading.
AIMS Ivabradine (Iva) has shown beneficial structural and functional effects in clinical and experimental heart failure (HF), but its action in combination with mechanical unloading (MU), such as during treatment with left ventricular assist devices (LVAD), is unknown. The aim of this study was to investigate the effects of Iva during MU, in a rodent model of HF. METHODS AND RESULTS We studie...
متن کاملInjurious mechanical compression of bovine articular cartilage induces chondrocyte apoptosis.
A bovine cartilage explant system was used to evaluate the effects of injurious compression on chondrocyte apoptosis and matrix biochemical and biomechanical properties within intact cartilage. Disks of newborn bovine articular cartilage were compressed in vitro to various peak stress levels and chondrocyte apoptotic cell death, tissue biomechanical properties, tissue swelling, glycosaminoglyca...
متن کاملthe influence of the neo-platonic concept of poetic imagination on wordsworth’s poetry
بر اساس نظریه افلاطون در باره شعر خلاقیت هنری مورد انتقاد قرار گرفته است. نظریه کلی در مورد شعر این بود که شعر از ظواهرتقلید میکند و نه حقیقت. چون سایه ای از حقیقت است. اما با پیدایش فلسفه نو افلاطونی، انتقاتات قبلی در مورد شعر و شاعری اصلاح شد. فلوطین در کتاب انئید، اساس خلق هنری را بر محور مُثل افلاطونی قرار داد. وی باور داشت که هنر مندان در خلق آثار هنری، تحت تاثیر مُثل افلاطونی بوده و عوالمی ...
Articular Chondrocyte Mechanics at Different Loading Rates
INTRODUCTION Mechanical impact loading is known to cause cell death and to lead to the onset and progression of osteoarthritis [1]. In order to understand why in-situ cells die readily following impact loading but remain unaffected when the same load is applied at a slow rate, we used a Finite Element model of articular cartilage and chondrocytes to study the in-situ cell mechanics, which canno...
