Carrageenan-induced arthritis model. (a) Experimental design of carrageenan-induced arthritis model. Twenty-eight male mice (12-week-old) were registered in this study. Mice were randomly divided into two groups: carrageenan group (CA) and carrageenan + follistatin (CA + FLT) group (/group). Histological analyses were performed at days 3 and 14. (b, c) Procedure of intra-articular injection of carrageenan. PT: patellar tendon.
