Nature Biotechnology replies:

The current version of Stemedica's website (http://www.stemedica.com/) neither publicizes treatments in stem cell clinics nor promotes them. In the process of fact checking the Qiu article, Nature Biotechnology editors twice checked the Stemedica website in June and August. When the website was checked on June 24, 2009, wording was present on the website indicating that the company was still publicizing treatments in stem cell clinics at that time. A subsequent check of the website on August 24 was unsuccessful as the website was not working. Evidence from the Internet Archive—as recent as 2008—does indicate that Stemedica publicized treatments in the past on its website (http://web.archive.org/web/20080222212144/www.stemedica.com/treatmentcenters/; http://web.archive.org/web/20071008142206/www.stemedica.com/patients/application/).
