Abstract (original English)

The concept of utilizing biological waste as a resource dates back centuries, with early practices in traditional medicine repurposing discarded tissues for healing purposes. In recent decades, advances in stem cell biology have revitalized this concept by identifying multipotent stem cells within various waste materials, including urine, adipose tissue, follicular fluid, umbilical cord blood, fetal annexes, menstrual blood, and dental pulp byproducts. These sources offer a minimally invasive, ethically sound, and cost-effective alternative to conventional stem cell harvesting methods. Stem cells derived from waste materials exhibit robust proliferative abilities and multilineage differentiation potential, positioning them as valuable tools for regenerative medicine, tissue engineering, and personalized therapeutic applications. Clinical studies highlight their promise. For example, mesenchymal stem cells from adipose tissue and umbilical cord blood have shown safety and some effectiveness in early trials. These studies report improvements of up to 30-40% in recovery scores for osteoarthritis and ischemic heart disease, as well as a 20-35% decrease in inflammatory markers for autoimmune disorders. Cord blood stem cell transplants have shown 70-90% survival rates in children with blood cancers. This underscores the clinical potential of waste-derived stem cells. However, regulat
