Characterization and identification of fibrocytes was performed at T0 and T8 by FACS (Beckman Coulter Company) using anti-CD45 (anti-CD45-krome orange, Beckman Coulter Company), anti-COL I (anti-COL I-FITC, Milli-Mark, Millipore), anti-CXCR4 (anti-CXCR4-PE, Beckman Coulter Company), anti-CD14, anti-CD86, and anti-HLA-DRII monoclonal antibodies (anti-CD14-alexa Fluor 750, anti-CD86-PC7, and anti-HLA-DRII-PC5.5, Beckman Coulter Company) [30 (link)].
Relevant isotype controls for each monoclonal antibody were used in the initial setup and frequently between tests.
