Patent number: 10883080Abstract: An object of the present invention is to obtain a thicker animal cell composition by a simple and less expensive method. Namely, an object of the present invention is to provide a method for culturing a thicker animal cell composition by eliminating the hypoxia associated with animal cell compositions, a method for producing an animal cell composition containing unicellular algae, and an animal cell composition. The present invention provides a method for culturing an animal cell composition in a culture medium in the presence of unicellular algae and under exposure to light. According to the method of the present invention, oxygen can be continuously supplied in the culture medium, cell damage is alleviated, and a thicker cell composition can be obtained in the absence of a capillary network.Type: GrantFiled: June 24, 2016Date of Patent: January 5, 2021Assignee: TOKYO WOMEN'S MEDICAL UNIVERSITYInventors: Tatsuya Shimizu, Yuji Haraguchi, Yuki Kagawa, Katsuhisa Sakaguchi
