TGFB2 and chondrosarcoma: Masi et al. showed that chondrosarcomas that overexpress TGF-β1 and TGF-β2 have significantly higher expression of the cell proliferation marker, MIB-127, whereas Boeuf et al. found no effect of TGF-β or BMP signalling on the growth of chondrosarcoma cell lines, JJ012 and SW135328.
