A-F: Immunohistochemistry for CD42b in ET (A, B), prefibrotic PMF mf0 (C, D) and fibrotic PMF (E, F). Confocal laser microscopy reveals dendritic processes (B, D, F; green staining) whereas in conventional immunohistochemistry predominantly cross sections are seen (brown staining) which increase in density in fibrotic PMF (CD42b; ×400) [17].
