Cell, 2009•cell.comGiven the importance of stem cells to adult tissues, it has long been postulated that stem
cells divide infrequently to preserve their long-term proliferation potential and to prevent the
acquisition of errors during DNA replication. Yet, some stem cells must be able to continually
churn out progeny in tissues that rapidly turn over or are subject to sudden injuries or growth
spurts. This Review explores the challenges that mammalian stem cells face in balancing
the competing demands of proliferation and differentiation in tissues.
