Clones in blood and stratified epithelial cells, and their drivers
1Institute of Medicine, University of Tsukuba.
Abstract:
The term "clone" is commonly used in the medical and life sciences to denote a genetically identical population, at both the individual and cellular levels. The concept of clonal expansion is of fundamental importance in cancer research. The advent of advanced sequencing technologies has elucidated the clonal nature of intermediates between normal cells and cancer cells. This review underscores seminal discoveries in the blood and stratified squamous epithelial systems, emphasizing the pivotal role of mutations in DNA modifier genes and Notch pathway genes, respectively, as drivers of clonal expansion. Despite the distinct nature of these systems and their genetic backgrounds, a common biological principle emerges.

Adult stem cells
Adult stem cells are tissue-specific; hence, they divide to develop the tissue from which they originate. One type of adult stem cell is the epithelial stem cell, which gives rise to the keratinocytes in the multiple layers of epithelial cells in the epidermis of the skin. Adult bone marrow has three distinct types of stem cells:...
