Abstract
The invention provides compositions for making hydrogels with improved mechanical properties, particularly for biological cultures. It provides methods for making the hydrogels and for using them. Exemplary hydrogels are made from irradiated or oxidized alginate compositions. Such hydrogels are useful for, especially, culturing follicles in vitro.
