This image of a section from developing bone shows trabeculae of woven bone, which is characterized by lacunae occupied by osteocytes, and a basophilic ground substance that lacks a lamellar substructure. The woven bone is often associated with fragments of cartilage matrix, which are palely stained and cell-free. In a couple of places, pink-staining lamellar bone has been laid down on the surface of the woven bone. Note that the lacunae of lamellar bone are in parallel rows, whereas the lacunae of woven bone show no particular arrangement. Two blood vessels containing erythrocytes can also be seen.
Stain = H&E.
