Cutting-edge research in regenerative medicine demonstrates substantial progress. A novel scalable platform enables mass production of standardized extracellular vesicles from induced mesenchymal stem cells, ensuring consistent quality for clinical applications, including treatment of pulmonary fibrosis. Advances in 3D printing have produced personalized implants for anterior cervical spine surgery, marking the first clinical case with custom-fitted devices. Stem cell-derived liver organoids further the study of dengue virus pathogenesis, while bioengineered co-grafts show promise for retinal repair, expanding therapeutic possibilities in tissue regeneration.
