Stem cell niche models. In “simple” niches stem cells divide asymmetrically to make one stem cell daughter and a committed progenitor daughter. In “storage” niches stem cells near the niche boundary respond to the attractive signal by migrating out of the niche and subsequently differentiating. Remaining stem cells divide symmetrically to replenish the stem cell pool.
