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 کاملStudy of Expression Level of Cartilage Genes in Rat Articular Chondrocyte Monolayer and 3D Cultures using Real Time PCR
Purpose: to compare the expression level of certain genes related to cartilage and non-cartilage tissues at monolayer and alginate cultures derived from rat articular cartilage. Materials and Methods: Articular cartilage was harvested from knee joints of 10 male rats and was digested using enzymatic solution consisting of 0.2% collagenase I and 0.1% pronase. Released chondrocyte were then plate...
متن کاملStudy 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 ...
متن کاملThe Interplay between Chondrocyte Redifferentiation Pellet Size and Oxygen Concentration
Chondrocytes dedifferentiate during ex vivo expansion on 2-dimensional surfaces. Aggregation of the expanded cells into 3-dimensional pellets, in the presence of induction factors, facilitates their redifferentiation and restoration of the chondrogenic phenotype. Typically 1×10(5)-5×10(5) chondrocytes are aggregated, resulting in "macro" pellets having diameters ranging from 1-2 mm. These macro...
متن کاملExpression patterns of chondrocyte genes cloned by differential display in tibial dyschondroplasia.
Tibial dyschondroplasia (TD) appears to involve a failure of the growth plate chondrocytes within growing long bones to differentiate fully to the hypertrophic stage, resulting in a mass of prehypertrophic chondrocytes which form the avascular TD lesion. Many biochemical and molecular markers of chondrocyte hypertrophy are absent from the lesion, or show reduced expression, but the cause of the...
