Experimental groups. Chondrocytes were distributed to six experimental groups, exposing them to either static cell culture, static culture followed by RPM exposure or RPM exposure only. The medium was additionally supplemented with 20 mM gadolinium or left untreated.

Group Name	Chemical Treatment	Mechanical Treatment
Control, UT	Untreated	8 days static culture
Adherent, UT	Untreated	2 days static culture followed by 6 days RPM exposure
Suspended, UT	Untreated	8 days RPM exposure
Control, Gd	Gadolinium	8 days static culture
Adherent, Gd	Gadolinium	2 days static culture followed by 6 days RPM exposure
Suspended, Gd	Gadolinium	8 days RPM exposure
