Cancer stem cells (CSCs) have been linked to the maintenance and progression of several tumours, but the properties of human CSCs are not well known. Reprogramming of human somatic cells during neoplastic in vitro transformation is shown to confer the properties of stem cells to primary differentiated fibroblasts. The cells that give rise to tumours in this case express the SSEA-1 antigen.
