A method for freeze-drying a hydrogel composition is disclosed, the method comprising providing the hydrogel composition, wherein the hydrogel composition comprises cellulose nanofibrils and/or cellulose nanocrystals, at least one saccharide, at least one amino acid, and biologics; and freeze-drying the hydrogel composition, thereby obtaining a freeze-dried hydrogel composition.

Method for freeze-drying a hydrogel composition and a freeze-dried hydrogel composition

The present disclosure relates to a method for controlling freeze-drying of a hydrogel wherein the method comprises adjusting the residual water content of the freeze-dried hydrogel, and to a freeze-dried hydrogel composition comprising nanoscale cellulose and a at least one biomolecule selected from an oligosaccharide or a disaccharide. The present disclosure further concerns the use of the freeze-dried hydrogel composition for cell culturing, a cell culturing scaffold as well as a process for manufacturing a reconstituted hydrogel.

Controlling freeze-drying of a hydrogel

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.
