Immunohistochemistry for PLIN2 (A-D) and PLIN3 (E, F) on paraffin sections. In the healthy endometrium PLIN2 positive lipid droplets were present in the surface (A) and glandular epithelium (C). In pyometra samples a high number of PLIN2 stained lipid droplets were seen in surface, glandular and crypt epithelia (B, D). Healthy endometrial samples were almost devoid of PLIN3 signals (E), whereas pyometra sections showed moderate to strong signals in the surface epithelium (F). Scale bars (A, B) = 100 μm, (C) = 20 μm, (D) = 50 μm, (E, F) = 50 μm
