    Cell Stem Cell. 2009 Jul 2;5(1):6-8.

    Stem cell aging and aberrant differentiation within the niche.

    Comment on:

    Stem cells age, but the underlying mechanisms remain unclear. In a recent issue of Cell, Inomata and colleagues (2009) show that DNA damage, a prime suspect in stem cell aging, causes graying and loss of melanocyte stem cells by inducing premature differentiation, without inducing apoptosis or senescence.
