Figure 5From: Isolation and characterization of rheumatoid arthritis synovial fibroblasts from primary culture — primary culture cells markedly differ from fourth-passage cellsMorphology of negatively isolated RA-SFB and macrophages upon reculture. When recultured, the RA-SFB obtained by negative isolation with Dynabeads® M-450 CD14 showed almost exclusively spindle-shaped, flat or stellate morphology (A). Recultured CD14+ cells (B) exhibited small, round, macrophage-like morphology with attached magnetobeads, and contained only very few cells with FB morphology.
