Transcriptomic data of MDA-MB-231 cells adapted to culture in media containing 0 mM or 2 mM metformin and cultured as mammospheres

We report the single-cell RNA sequencing data obtained from MDA-MB-231 breast cancer cells cultured in standard DMEM (high glucose) media, or adapted to culture in standard DMEM (high glucose) media containing 2 mM metformin, and then cultured as mammospheres Examination of transcriptomic changes in MDA-MB-231 breast cancer cells mammospheres in response to adaptation to culture in 2 mM metformin
