Contribution of stem cells and differentiated cells to epidermal tumours

David M Owens et al. Nat Rev Cancer. 2003 Jun.

Abstract

The outer covering of the skin--the epidermis--is subject to sustained environmental assaults. As a result, many cells acquire potentially oncogenic mutations. Most cells are lost through differentiation, and only long-term epidermal residents, such as stem cells, accumulate the number of genetic hits that are necessary for tumour development. So, what genetic and environmental factors determine whether a mutant stem cell forms a tumour and what type of tumour will develop?
