A nanocellulose (NC)-containing medium is a promising candidate for cell storage that allows cell floating without any stirring. We here found that the NC medium was spatially heterogeneous in terms of its rheological properties. The characteristic length of the heterogeneity was a few tens of micrometers and it decreased upon sonication treatment. The length scale of the heterogeneity affected the cell suspension; the NC medium having a smaller length scale suppressed the cell sedimentation effectively.
