“…Conversely, C-20/A4 tested positive for MMP-3 unlike previously shown [Finger et al, 2004], with more modest levels of aggrecan compared to A13/BACii. The expression of MMP-3, MMP-9 and MMP-13 has been associated with chondrosarcomas [Kawashima et al, 1997;Soderstrom et al, 2001;Kuroki et al, 2002;Zyada and Shamaa, 2008], and correlates with their grading and capacity to metastasize to the lungs [Sakamoto et al, 1999;Hou et al, 2011], coincidentally, the main target for B[ ␣ ]P tumourgenesis in vivo. As some established chondrosarcoma cell lines including swarm rat chondrosarcoma [Breitkreutz et al, 1979], OUMS-27 [Kudo et al, 2007] and HCS-TG [Kudawara et al, 2004] produce col2, it may be suggested that A13/BACii is a B[ ␣ ]P-transformed chondrosarcoma cell line.…”
