Gene expression of invasive lobular carcinoma tumor epithelium and tumor stroma isolated by laser-capture microdissection

We used laser-capture microdissection (LCM) to separate tumor epithelium (TE) from stroma (TS) in 23 ILC samples. Gene expression analysis was used to identify genes that are enriched in the stroma of ILC, but not IDC or normal breast. Gene expression data was generated for a total of 22 TE and 18 TS samples, including 17 pairs of TE and TS samples from the same patients.
