Most of these devices are easy to use, allowing the elaboration of products and its application within the same procedure. Regardless of the questionable efficacy and safety of many of the treatments offered under the claim of stem cells or regenerative medicine, most of the centres and professionals offering these treatments are unaware of the legal requirements and implications of their use. A common confusion consists in not distinguishing between the authorization required by the equipment itself, considered a medical device, and the authorization for the use of the product obtained, usually considered a medicinal product (whether advanced therapy or not) or a transplant. Moreover, these treatments frequently have an experimental nature. In that case, in addition to requiring the corresponding ethical evaluation and the authorization of various regulatory bodies, their administration must be offered free of charge, obtaining the patient's informed consent and after contracting a specific insurance policy. In this article we present a brief summary of the main requirements for the application of these autologous biological products with the aim of serving as a guide both for the professionals who prescribe them and for those who inspect the centres where the products are administered. Finally, we include some recommendations for patients. YR 2020 FD 2020-03-09 LK http://hdl.handle.net/10668/15234 UL http://hdl.handle.net/10668/15234 LA es DS RISalud RD Apr 10, 2025
