A cDNA clone of about 2500 base pairs was prepared from the human osteosarcoma cell line U-2 OS by hybridizing with a v-sis probe. Sequence analysis showed that this cDNA contains the coding region for the PDGF-B chain. It is discussed that the mitogen secreted by these osteosarcoma cells contains the PDGF-B chain and is probably a homodimer of two B-chains.
通过与v-sis探针杂交，从人骨肉瘤细胞系U-2 OS制备了一个约2500个碱基对的cDNA克隆。序列分析表明，该cDNA包含血小板源性生长因子-B链（PDGF-B链）的编码区。据讨论，这些骨肉瘤细胞分泌的促有丝分裂原含有PDGF-B链，可能是两条B链的同二聚体。
