An ad hoc planning committee will plan and conduct a public workshop to examine and discuss stem cell tourism. The goal of the workshop will be to examine the extent of unsubstantiated stem cell therapy offerings, the potential risks involved, the evidentiary basis for claims of efficacy, and to discuss whether there is a need for coordinated efforts to regulate stem cell clinic offerings globally. One issue that will be considered at the workshop is whether the information available to the public is adequate to sort out options. The workshop will advance discussions among a broad array of stakeholders which may include government officials, industry representatives, professional societies, academic researchers, regulators, providers, and patients. The planning committee will develop the workshop agenda, select and invite speakers and discussants, and moderate the discussions. An individually-authored summary of the workshop will be prepared by a designated rapporteur in accordance with institutional policy and procedures. This workshop will be held jointly with the International Society for Stem Cell Research.
