摘要

We have established a new co-culture system in which human mammary epithelial cells (HMEC) and human mammary tumor cells (HMT) are physically grown together. We hypothesized that cells in co-culture (CC) would generate gene expression profiles different from homogeneous cell populations. In this study, cells were incubated with blue or red CellTracker Dyes and co-cultured. Our novel capture system allowed cells to be co-cultured and then quickly separated while maintaining 90% viability. Using deconvolution microscopy, co- cultured HMEC were observed to form focal, gland-like structures surrounded by TTUderived from an invasive ductal carcinoma. Using a differential trypsinization technique, cell populations were rapidly separated to perform RNA extractions performed.
