[Cloning cDNA for the ha-SDGF gene from a Syrian hamster cell line with increased metastatic potential using...

Using subtractive hybridization, a cDNA library containing over 50% of clones specific for a highly metastatic cell line was obtained from two hamster embryo fibroblast lines with different metastatic potentials. Most of the clones (83%) contained new sequences. One clone contained the ha-SDGF gene cDNA homologous to SDGF cDNA from rodents. The level of ha-SDGF mRNA expression was considerably higher in the highly metastatic cell line.
