Publication number: 20250250531Abstract: The invention primarily relates to a method for isolating and characterizing nucleus pulposus progenitor cells. The method initially involves cutting nucleus pulposus tissue into multiple tissue blocks and then enzymatically digesting these blocks. After digestion, these tissue blocks are cultured in a culture dish. When cells form clusters at the bottom of the dish, specific embryonic stem cell genes (such as Nanog, Oct-4, SOX2) are used to select nucleus pulposus progenitor cells from the clusters. Furthermore, this method employs specific proteins and genetic markers to select nucleus pulposus progenitor cells with mobility and/or mesenchymal stem cell characteristics, as well as to further select cells with anti-inflammatory abilities. Finally, the invention discloses a use of the nucleus pulposus progenitor cells obtained by the method in the manufacture of a pharmaceutical composition for the treatment of lower back pain, offering a new strategy for the treatment of lower back pain.Type: ApplicationFiled: April 22, 2024Publication date: August 7, 2025Applicant: ASTEROGENE Biomedical Co., Ltd.Inventors: WEI-HUNG CHEN, SHIH-CHEN TSAI
