Differential DNA Damage Response in Stem and Progenitor Cells.
Summary of "Differential DNA Damage Response in Stem and Progenitor Cells."
The long lifespan of tissue-specific stem cells suggests that they may respond differently to DNA damage than downstream cells. In this issue of Cell Stem Cell, two groups address this hypothesis by examining DNA damage responses in hematopoietic stem and progenitor cells (Milyavsky et al., 2010; Mohrin et al., 2010).

Medical and Biotech [MESH] Definitions
Multipotent Stem Cells
Specialized stem cells that are committed to give rise to cells that have a particular function; examples are MYOBLASTS; MYELOID PROGENITOR CELLS; and skin stem cells.

Myeloid Progenitor Cells
Stem cells derived from HEMATOPOIETIC STEM CELLS. Derived from these myeloid progenitor cells are the MEGAKARYOCYTES; ERYTHROID CELLS; MYELOID CELLS; and some DENDRITIC CELLS.
Relatively undifferentiated cells that retain the ability to divide and proliferate throughout postnatal life to provide progenitor cells that can differentiate into specialized cells.
Fetal Stem Cells
Cells derived from a FETUS that retain the ability to divide, proliferate and provide progenitor cells that can differentiate into specialized cells.
Hematopoietic Stem Cells
Progenitor cells from which all blood cells derive.
Redox status is a critical modulator of stem and progenitor cell function. In this issue of Cell Stem Cell, Le Belle et al. (2011) demonstrate that oxidation promotes self-renewal of neuroepithelial...
