| Research Abstract |
Osteophyte formation is a common phenomenon in osteoarthritis. Endochondral ossification is considered an important pathophysiological process for osteophyte fornlation. We investigated whether the deletion of smoothened (Smo), a key component of the hedgehog pathway in the process of enchondral ossification, inhibits osteophyte formation in nlouse osteoarthritis. The attenuation of osteophyte was shown in the mice deleted Smo, indicating that hedgehog signaling has a critical role in the osteoarthritis.
