METHOD OF PRESERVING TISSUE EQUIVALENT AND TISSUE EQUIVALENT PRESERVED IN FROZEN STATE

摘要

A method of preserving a tissue equivalent in a frozen state whereby the survival ratio of frozen cells and the biological activity of thawed cells are elevated and the steps are simplified; and a tissue equivalent preserved in a frozen state which is obtained by this method. Cells suspended in a liquid for frozen preservation are inoculated into a substrate and then frozen before the cells adhere to the substrate.
