Figure 6From: Atrial fibrosis in a chronic murine model of obstructive sleep apnea: mechanisms and prevention by mesenchymal stem cellsFibrosis assessment in OSA + MSC and Sham + S rats. A. Picrosirius-stained photomicrographs of atrial sections, right ventricular (RV) sections and left ventricular (LV) sections from Sham + Saline (n = 7) and OSA + MSC (n = 8) rats. Atria and ventricular samples were stained in different days, and pictures obtained at different magnification, so results from atria and ventricles should not be compared. B. Quantification of collagen fraction in the atria, RV and LV measured in Picrosirius-red stained samples (Mean ± SEM).Back to article page
