The human mammary epithelial cancer (HMEC) cell line was derived from the glandular tissue of a patient suffering from breast cancer. Research studies on the HMEC cell line have shown the cells exhibiting a cuboidal morphology with a series of patterned swirls. The HMEC cell line is very useful in pre-clinical biomedical research done at Altogen Biosystems involving breast cancer treatments.
