INSERT TITLE. Marrow fibrosis/reticulin content is graded in the reticulin-stained section (right), the corresponding hematoxylin and eosin (H&E)–stained section (left), and autofluorescence of the H&E-stained section (center). The bone marrow images were taken with an Olympus BH2 microscope (Olympus, Tokyo, Japan) with a 20× objective and a final magnification of 100×. The numeric aperture of the Plan Apochromat lens was 0.70. Images were transferred by JPEG high resolution (24-bit color at 1200×) using 800 software Olympus DP-12 and Olympus DP-12 BW acquisition software. Adobe Photoshop CS version 8 (Adobe Systems, San Jose, CA) was used as word processing software.
