Culture medium composition

Abstract

The present invention provides a culture method of cells and/or tissues including culturing cells and/or tissues in a suspended state by using a medium composition having an effect of preventing sedimentation of cells and/or tissues, which is afforded by substantially retaining the cells and/or tissues without substantially increasing the viscosity of the solution by nanofibers which have been added to the solution and uniformly dispersed in the liquid medium, and the like.

1 . A liquid composition comprising:
 (1) a culture medium,   (2) an adherent cell, and   (3) a chitin nanofiber,   
       wherein the chitin nanofiber is dispersed in the culture medium and form a three-dimensional network in the culture medium so that the adherent cell can be dispersed while spreading three-dimensionally and proliferate in the state of being attached to the chitin nanofiber. 
     
     
         2 . The liquid composition of  claim 1 , wherein the liquid composition has a chitin nanofiber content of 0.001% (weight/volume) to 0.1% (weight/volume).
