Journal of Translational Medicine 2011 9 29 http content 9 1 29 TRANSLATIONAL MEDICINE REVIEW Open Access Risk factors in the development of stem cell therapy Carla A Herberts1 Marcel SG Kwa2 Harm PH Hermsen1 Abstract Stem cell therapy holds the promise to treat degenerative diseases cancer and repair of damaged tissues for which there are currently no or limited therapeutic options. The potential of stem cell therapies has long been recognised and the creation of induced pluripotent stem cells iPSC has boosted the stem cell field leading to increasing development and scientific knowledge. Despite the clinical potential of stem cell based medicinal products there are also potential and unanticipated risks. These risks deserve a thorough discussion within the perspective of current scientific knowledge and experience. Evaluation of potential risks should be a prerequisite step before clinical use of stem cell based medicinal products. The risk profile of stem cell based medicinal products depends on many risk factors which include the type of stem cells their differentiation status and proliferation capacity the route of administration the intended location in vitro culture and or other manipulation steps irreversibility of treatment need possibility for concurrent tissue regeneration in case of irreversible tissue loss and long-term survival of engrafted cells. Together these factors determine the risk profile associated with a stem cell based medicinal product. The identified risks . risks identified in clinical experience or potential theoretical risks . risks observed in animal studies include tumour formation unwanted immune responses and the transmission of adventitious agents. Currently there is no clinical experience with pluripotent stem cells . embryonal stem cells and iPSC . Based on their characteristics of unlimited self-renewal and high proliferation rate the risks associated with a product .
