Expression data of 4T1 mammary cancer cells cultured in MSC-conditioned medium or co-cultured with MSCs. Mus musculus

4T1 mammary cancer cells exihibit higher proliferation and metastatic ability when cultured in conditioned medium from mesenchymal stem cells . Also, co-implantation with MSCs, 4T1 tumors show higher tumor growth and metastasis. We used microarrays to detail the global programme of gene expression underlying the alteration of cell behaviour Overall design: RNA was extrated from 4T1 cells cultured in MSC-CM or regular medium as well as 4T1 cells isolated from co-cultured with MSCs. Gene expression of these cell groups was acquired from Affymetrix microarray analysis using mouse 430 2.0 array chip.
