Indeed, we have already demonstratedmechano-NPS’s ability to distinguish between LEP and MEP lineages in mixedpopulations, between epithelial cells from pre- or post-menopausal women, andbetween normal and immortal transformed epithelial cells from the same individual.The proportions of MEP and LEP subpopulations in mammary epithelium is highlyassociated with age of women47, and when combined with distinct deformationrecovery phenotypes in normal and transformed cells, mechano-NPS may yield valuableinformation regarding risk or diagnosis of breast cancer. Here, LEP is linked to breast cancer.
