TBX3 and chondrosarcoma: Therefore, before we engineered hMSCs to overexpress TBX3, we compared the status of TBX3 mRNA and protein in three adipose-derived hMSC cell lines (hMSC line 1-3) as well as chondrosarcoma (SW1353) and liposarcoma (SW872) cells by qRT-PCR and western blotting respectively.
