Cell cycle, 2010•Taylor & FrancisAging is associated with profound changes in bone mass and body composition. Emerging
evidence supports the hypothesis that alterations in mesenchymal stromal cell fate are a
critical etiologic factor. In addition, timekeeping at the cellular level is affected as aging
progresses, particularly in the adipocyte. In this Extra View we discuss the interactive role of
three molecules, PPARγ, nocturnin and IGF-I in regulating stem cell fate in the marrow, and
the potential implications of this network for understanding cellular aging.
