Abstract:
The present disclosure provides a method for freeze-drying cells in a hydrogel comprising nanofibrillar cellulose, the method comprising providing a hydrogel comprising nanofibrillar cellulose, providing cells, combining the cells and the hydrogel comprising nanofibrillar cellulose to form a cell system, and freeze drying the cell system to obtain dried cells in a hydrogel comprising nanofibrillar cellulose. The present disclosure also provides a freeze-dried hydrogel comprising nanofibrillar cellulose and cells.
