Key characteristics during histopathological identification. (A) ON lesion was shown by trabecular bone containing many empty lacunae. (B) In ON⁺ rabbits, thrombi were predominantly found in small marrow vessels in ON⁺ rabbits, and marrow was mainly occupied by numerous fat cells with increased size in ON⁺ rabbits (D) compared to normal rabbits (C). Strong immunoreactivity was found in both marrow cells (E) and endothelium (G) in the CON group at week 1 and 2 post-induction. Weak immunoreactivity was found in both marrow cells (F) and endothelium (H) in either the baseline or H-ICT group at week 1 and 2 post-induction. Baseline information not shown here. Arrow pointed particles in G and H were angiographic substance.
