title: The missing niche for spermatogonial stem cells: do blood vessels point the way?
abstract: Although spermatogonial stem cell niches have been defined in lower organisms, their definitive localization in mammalian seminiferous tubules has been elusive. In a recent Science paper, Yoshida et al. (2007) elegantly demonstrated a vascular and interstitial tissue-associated niche for undifferentiated spermatogonia in the mouse.
