Patent registration for exosome separation method for chondrocyte regeneration and proliferation at Barunseang Hospital has been completed
Oct 16, 2025
The method of separating exosomes for cartilage regeneration for cartilage regeneration and proliferation applied by Barunseang Hospital (Hospital Director Seo Dong-won) recently completed domestic patent registration.
The Barunseang Hospital Cartilage Regeneration Research Institute has carried out a national project organized by the Ministry of Health and Welfare and the Ministry of Science and ICT, and has continued research on knee joint cartilage regeneration treatment.
In the process, ▲'Exosome separation method for cartilage cell regeneration and proliferation'▲' A composition for the treatment of arthritis containing exosomes separated from platelet rich plasma as active ingredients' has been patented, and the second one has already been registered last year.
The patent relates to a method of separating exosomes for chondrocyte regeneration and proliferation among treatment strategies that induce damaged cartilage regeneration using exosomes separated from the patient's platelet-rich plasma (PRP).
The institute completed the patent by increasing the yield of exosomes through its own separation method and confirming that the proliferation and recovery rate of chondrocytes is significantly improved when treated with damaged chondrocytes.
Lee Yong-soo, director of the Cartilage Regeneration Research Institute, said "Exosomes are substances produced by cells and have anti-inflammatory and cell regeneration effects and are applied in various therapeutic fields. However, the expected effects are also different due to the wide variety of separation methods. The newly registered patent is the result of independently developing a separation method for chondrocyte proliferation and regeneration exosomes. It is expected to be used as a key technology for the development of cartilage regeneration treatments in the future because it is a composition for chondrocyte regeneration and proliferation containing exosomes as an active ingredient and has high yield and excellent regeneration effects at the same time."
