Could you please clarify what type of stem cells are used in this treatment—for example, whether they are autologous (from the patient), allogeneic (from a donor), or specifically mesenchymal stem cells? Additionally, are these stem cells and the treatment protocols officially approved or regulated by Korean health authorities such as the Ministry of Food and Drug Safety (MFDS)? I’m also interested in understanding how safety, sourcing, and quality control are ensured throughout the process.
