Differential expression—the numbers are the ratio of the relative expression level of a specific gene in PC-treated hTERT-OA 13A FLSs compared with the relative expression level of the specific gene in the untreated hTERT-OA 13A FLSs. Differential expression—the numbers are the ratio of the relative expression level of a specific gene in PC-treated primary FLSs compared with the relative expression level of the specific gene in the untreated primary OA FLSs.
