Description: Human mammary epithelium, HME1 cell line, was derived from a 53-year-old patient undergoing reduction mammoplasty surgery (no history of breast cancer). The HME1 cells were immortalized by infection with the retrovirus pBabepuro+hTERT vector and cultured in complete growth medium containing puromycin until stable clones were selected. These cells do not undergo growth arrest; in cell culture, due to the exogenous expression of the telomerase gene (1-5).
