Abstract

Development of metastasis is a leading cause of cancer-induced death. Acquisition of an invasive tumor cell phenotype suggests loss of cell adhesion and basement membrane breakdown during a process termed epithelial-to-mesenchymal transition (EMT). Recently, cancer stem cells (CSC) were discovered to mediate solid tumor initiation and progression. Prostate CSCs are a subpopulation of CD44+ cells within the tumor that give rise to differentiated tumor cells and also self-renew. Using both primary and established prostate cancer cell lines, we tested the assumption that CSCs are more invasive. The ability of unsorted cells and CD44-positve and -negative subpopulations to undergo Matrigel invasion and EMT was evaluated, and the gene expression profiles of these cells were analyzed by microarray and a subset confirmed using QRT-PCR. Our data reveal that a subpopulation of CD44+ CSC-like cells invade Matrigel through an EMT, while in contrast, CD44 cells are non-invasive. Furthermore, the genomic profile of the invasive cells closely resembles that of CD44+CD24 prostate CSCs and shows evidence for increased Hedgehog signaling. Finally, invasive cells from DU145 and primary prostate cancer cells are more tumorigenic in NOD/SCID mice compared with non-invasive cells. Our data strongly suggest that basement membrane invasion, an early and necessary step in metastasis development, is mediated by these potential cancer stem cells.

Error bars represent SEM from two independent samples and were normalized to expression of 18S rRNA. All changes are significantly different from top cells (P < 0.05) with the exception of TGFB1 and vimentin in LNCaP cells. Fold-induction changes for LNCaP cells: 0.355-CD24, 0.308-E-cadherin, 0.733-vimentin, 3.622-BMI1, 3.690-Nanog, 3.355-FGF2 and 1.2 for TGFB1.
