Patent number: 11649433Abstract: The present invention relates to a method for controlling differentiation of pluripotent stem cells, which method comprises selecting a laminin or a fragment thereof based on binding affinity for the pluripotent stem cells and inducing differentiation of the pluripotent stem cells in the presence of the laminin or a fragment thereof. Here, the binding affinity for cells can be assessed by time-course observation of the survival rate and motility of the cells. According to the present invention, a cell population containing any desired proportion of differentiated cells can be produced from pluripotent stem cells in a simple manner. The cell population obtained by this production method is very useful for cell therapy-based treatment strategies for diseases.Type: GrantFiled: January 31, 2018Date of Patent: May 16, 2023Assignee: Osaka UniversityInventors: Kohji Nishida, Kiyotoshi Sekiguchi, Ryuhei Hayashi, Shun Shibata

Publication number: 20210046122Abstract: The present invention addresses the problem of providing a novel therapeutic agent that is effective against diseases involving stratified squamous epithelial cells such as dry eye syndrome. The present invention is an agent for promoting normal differentiation/maturation of stratified squamous epithelial cells, which comprises a secretion of mesenchymal stem cells. It is preferable that the secretions not include animal serum, that the mesenchymal stem cells be adipose-derived mesenchymal stem cells, umbilical cord-derived mesenchymal stem cells, or bone marrow-derived mesenchymal stem cells, and that the stratified squamous epithelial cells be at least one selected from the group consisting of corneal epithelial cells, conjunctival epithelial cells, epidermal keratinocytes, oral epithelial cells, epiglottic epithelial cells, esophageal epithelial cells, vaginal epithelial cells, vocal fold epithelial cells, nasal epithelial cells, and nasal vestibular epithelial cells.Type: ApplicationFiled: January 11, 2019Publication date: February 18, 2021Applicants: OSAKA UNIVERSITY, ROHTO PHARMACEUTICAL CO., LTD.Inventors: Kohji NISHIDA, Ryuhei HAYASHI, Shun SHIBATA, Toru OKUBO, Yoichi HONMA
