Figure 5From: Decrease in expression of bone morphogenetic proteins 4 and 5 in synovial tissue of patients with osteoarthritis and rheumatoid arthritisImmunohistochemistry (IMH) and in situ hybridization (ISH) of synovial tissues for BMP-5. Histomorphological distribution of BMP-5 is comparable to that of BMP-4 (Figure 4). Original magnifications: immunohistochemistry (IMH): rheumatoid arthritis (RA), osteoarthritis (OA), normal donors (ND) ×20; in situ hybridization (ISH): RA, OA, ND ×40. BMP, bone morphogenetic protein.Back to article page
