Publication number: 20230270790Abstract: Amyotrophic lateral sclerosis (ALS) is a life-threatening neurodegenerative disease characterized by the progressive loss of motor neurons. Muse cells are endogenous reparative pluripotent-like stem cells distributed to various tissues. Once intravenously injected, such cells, upon sensing sphingosine-1-phosphate produced by damaged cells, settle selectively on damaged sites, and after homing, can exhibit multiphase effects including natural differentiation into tissue-protecting and tissue-reconstructing cells. In the present invention, with G93A-Tg mice serving as an ALS model, human Muse cells injected intravenously successfully homed into the lumbar cord, mainly at the pia mater and the lower white matter, and expressed glial-like forms and GFAP. Meanwhile, no such homing or differentiation was observed in the case of human mesenchymal stem cells (MSCs), and, rather, MSCs were found distributed to the lungs.Type: ApplicationFiled: July 15, 2021Publication date: August 31, 2023Applicants: NATIONAL UNIVERSITY CORPORATION OKAYAMA UNIVERSITY, TOHOKU UNIVERSITY, LIFE SCIENCE INSTITUTE, INC.Inventors: Koji ABE, Toru YAMASHITA, Mari DEZAWA, Yoshihiro KUSHIDA, Yumiko IWASE
