Antagonism between pro-chondrogenic growth factors and pro-inflammatory cytokines and the chondrogenic differentiation of human
INTRODUCTION: Cartilage loss through trauma or arthritis presents an important clinical challenge. Because sources of autograft are limited, the generation of cartilage repair tissue using mesenchymal progenitor cells (MPCs) – either ex vivo or in situ – represents an attractive alternative. Various members of the transforming growth factor (TGF) superfamily have been shown to direct chondrogen...
متن کاملFactors Regulating Chondrogenic Differentiation
Chondrogenesis is a co-ordinated differentiation process in which mesenchymal cells condensate, differentiate into chondrocytes and begin to secrete molecules that form the extracellular matrix. It is regulated in a spatio-temporal manner by cellular interactions and growth and differentiation factors that modulate cellular signalling pathways and transcription of specific genes. Moreover, post...
متن کاملAcid Ceramidase Maintains the Chondrogenic Phenotype of Expanded Primary Chondrocytes and Improves the Chondrogenic Differentiation of Bone Marrow-Derived Mesenchymal Stem Cells
Acid ceramidase is required to maintain the metabolic balance of several important bioactive lipids, including ceramide, sphingosine and sphingosine-1-phosphate. Here we show that addition of recombinant acid ceramidase (rAC) to primary chondrocyte culture media maintained low levels of ceramide and led to elevated sphingosine by 48 hours. Surprisingly, after three weeks of expansion the chondr...
متن کاملEffects of BIO on proliferation and chondrogenic differentiation of mouse marrow-derived mesenchymal stem cells
In vitro expansion of mesenchymal stem cell (MSCs) into large number is necessary for their application in cell-based treatment of articular cartilage defects. On the other hand, some studies have indicated that BIO (6-Bromoindirubin-3-Oxime) possesses mitogenic effects on cell culture. The objective of the present study was to examine the effect of BIO on in vitro expansion and chondrogenic di...
متن کاملRepressing of SOX6 and SOX9 in Situ Chondrogenic Differentiation of Rat Bone Marrow Stromal Cells
Introduction: SOX9 is a transcriptional activator which is necessary for chondrogenesis. SOX6 are closely related to DNA-binding proteins that critically enhance its function. Therefore, to carry out the growth plate chondrocyte differentiation program, SOX9 and SOX6 collaborate genomewide. Chondrocyte differentiation is also known to be promoted by glucocorticoids through unknown molecular mec...
