Nat. Biotechnol. 23, 807–815 (2005)

On page 808, in Table 1, the entry for MacroPore Biosurgery (which since the publication of this article has changed its name to Cytori Therapeutics) erroneously listed “liver-assist device (with subsidiary Xenogenics)” after “Cell-based therapies, bioresorbable therapies” in the business model column. It should have read simply, “Cell-based therapies, bioresorbable therapies.”
