Cancers in the upper layers of the skin are sustained by a continually renewing supply of aberrant stem cells, known as cancer stem cells. In a paper appearing in the journal Nature, a team led by EPFL/ISREC professor Joerg Huelsken has identified how this supply of cancer stem cells gets topped up, showing that a critical protein involved in cell signaling is important to maintain their numbers. The discovery could lead to treatments that would target the protein, thus destroying the cancer. (source: actualites.epfl.ch)
