The theory that cancer may be originated and sustained by a small proportion of stem-like, self-renewing cells (termed 'cancer stem cells') has gained support in recent years. Breast cancer stem cells have been identified as CD44+CD24- breast tumour cells and have recently been isolated and propagated in vitro. It has been demonstrated that these cells exclusively retain the ability to form new tumours in mouse models and that they display stem/progenitor cell properties.

However, at present, direct evidence that breast cancer-initiating cells can be propagated in vitro is still lacking. We report here the isolation and in vitro propagation of breast cancer-initiating cells from three breast cancer lesions and from an established breast carcinoma cell line.
