Fibroblast-like synoviocytes derived from patients with rheumatoid arthritis


ABSTRACT: Fibroblast-like synoviocytes (FLS) were cultured from synovial tissues from 19 RA patients. RNA was isolated using the Fast Track 2.0 kit (Invitrogen, Carlsbad, California)from the FLS cultures. Fluorescent cDNA probes were prepared from 1 ug experimental mRNA by oligo dT-primed polymerization using Superscript II reverse transcriptase in the presence of Cy5 labeled dCTP. A common reference mRNA sample (CRE) that consists of a mixture of mRNAs isolated from 11 different cell-lines, was labeled with Cy3. The Cy5 and Cy3 labeled cDNAs were pooled and hybridized to a 24,000 cDNA microarray. Set of arrays that are part of repeated experiments Biological Replicate Using regression correlation

Fibroblast-like synoviocytes derived from patients with rheumatoid arthritis show the imprint of synovial tissue heterogeneity: evidence of a link between an increased myofibroblast-like phenotype and high-inflammation synovitis.

<h4>Objective</h4>Given the heterogeneity of gene expression patterns and cellular distribution between rheumatoid arthritis (RA) synovial tissues, we sought to determine whether this variability was also reflected at the level of the fibroblast-like synoviocyte (FLS) cultured from RA synovial tissues.<h4>Methods</h4>Gene expression profiles in FLS cultured from synovial tissues obtained from 19 RA patients were analyzed using complementary DNA microarrays and hierarchical cluster analysis.
