BACKGROUND Tumor initiating stem-like cells (TISCs) are a subset of neoplastic cells that possess distinct survival mechanisms and self-renewal characteristics crucial for tumor maintenance and propagation. The induction of epithelial-mesenchymal-transition (EMT) by TGFβ has been recently linked to the acquisition of TISC characteristics in breast cancer.(More)
Interactions between embryonic cells are generally thought to have a central role in the control of development. When these morphogenic interactions are interrupted by either physical intervention or genetic defects, normal development is impaired. In accord with these experiments, specific interactions between embryonic cells have been demonstrated in(More)
