Abstract

The available data on DNA cosegregation in some stem cells are reviewed. Cairns was the first to assume cosegregation of template DNA strands for adult stem cells; i.e., all maternal DNA strands are preserved in one daughter cell, which remains a stem cell, while the newly synthesized DNA strands, which may contain errors, appear in the daughter cell that is committed to differentiation and passes to the transitory compartment of the cell population. The role of asymmetric mitosis in DNA cosegregation and maintenance of genetic information in stem cells is discussed.
