Differential staining of osteoid and bone with the RGB trichrome method. Osteoid seams (Ost) at the surface of bone (B) trabeculae (see A,B), and osteoid formation by osteoblasts (Ob in C,D), that become trapped and differentiate to osteocytes (Os in the inset in C). FT, fibrous tissue in the marrow.
