My lab is interested in the question of how and why somatic stem cells dysfunction with age. Throughout life, stem cells are responsible for replenishing and regenerating tissue, fundamentally maintaining “youthfulness.” With aging, this ability is lost, resulting in effects such as cognitive impairment, reduced immune response, deterioration of skeletal muscle, and difficulty in wound healing, for example. To develop methods to improve or rescue aging of somatic stem cells, we must understand not only how they age, but also how they remain young.
Recently we have shown that neural stem cells (NSCs) asymmetrically segregate cargoes (e.g. damaged proteins) when they divide, leaving one daughter cell more “clean” than the other. That daughter cell which inherits the damage has a slower proliferation rate than the more “clean” daughter, suggesting that this process may be used for cellular rejuvenation (Moore et al, 2015 Science). This asymmetric segregation is affected with age, suggesting that investigating the mechanisms and cargoes involved in this asymmetric inheritance may reveal a means to improve stem cell aging.
