Chondrocyte proliferation promoter, chondrocyte proliferation promoter method, and chondrocyte proliferation promoter screening method

摘要

It contains as an active ingredient an agonist for at least one receptor selected from adiponectin receptor 1 (PAQR1), adiponectin receptor 2 (PAQR2), adiponectin receptor 3 (PAQR3), and adiponectin receptor 4 (PAQR4). Provided are a chondrocyte proliferation promoting agent, a chondrocyte proliferation promoting method using the chondrocyte proliferation promoting agent, and a screening method for a chondrocyte proliferation promoting agent.
