科罗拉多州的一个研究团队开发出了实验性骨关节炎疗法，这些疗法似乎能再生受损关节，而不仅仅是缓解疼痛。在动物实验中，单次注射在数周内即将关节炎关节恢复至健康状态，而另一种疗法则通过利用机体自身的愈合细胞修复了软骨和骨缺损。
The work recently received a major boost from the federal Advanced Research Projects Agency for Health (ARPA-H), which announced that the team will move forward to the next stage of a project worth up to $33.5 million. The research is part of the ARPA-H Novel Innovations for Tissue Regeneration in Osteoarthritis (NITRO) program, led by ARPA-H Program Manager Dr. Ross Uhrich.
