Expression of transforming growth factor β isoforms in osteosarcoma variants: association of tgfβ1 with high-grade osteosarcomas

Abstract excerpt

Studies on osteosarcoma cell lines point to the potential importance of transforming growth factor beta (TGF beta) as an autocrine factor which controls the growth of human osteosarcomas. To define further the role of TGF beta isoforms in these neoplasms, a series of 27 osteosarcomas was studied using immunohistochemical, mRNA in situ hybridization, and reverse transcriptase-polymerase chain reaction (RT-PCR)...
