Genetic Regulation Of Hematopoietic Stem Cell Aging, Erin J. Oakley
Genetic Regulation Of Hematopoietic Stem Cell Aging, Erin J. Oakley
University of Kentucky Doctoral Dissertations
It is well documented that both quantitative and qualitative changes in the murine hematopoietic stem cell (HSC) population occur with age. In mice, the effect of aging on stem cells is highly strain-specific, thus suggesting genetic regulation plays a role in HSC aging. In C57BL/6 (B6) mice, the HSC population steadily increases with age, whereas in DBA/2 (D2) mice, this population declines. Our lab has previously mapped a quantitative trait locus (QTL) to murine chromosome 2 that is associated with the variation in frequency of HSCs between aged B6 and D2 mice. In these dissertation studies, I first aim to …
