stably transfected cells

https://doi.org/10.1351/goldbook.14193
Eukaryotic cells into which recombinant DNA has been introduced and incorporated into the genome, so that the cells replicate the new DNA in a stable fashion.
Note: The biological material thus obtained is expected to show low variability and therefore increase assay reproducibility.
