Claim 0:
1. A composition comprising stem cells; a cell culture medium; and a polyacrylamide hydrogel,
wherein the polyacrylamide hydrogel comprises acrylamide monomers, a cross-linking agent, and N-hydroxyethyl acrylamide (HEA), wherein a weight percent of the HEA is greater than 0% and less than 0.02% of a total weight of the polyacrylamide hydrogel,
wherein an elasticity modulus of the polyacrylamide hydrogel is 1 to 200 Pa,
wherein the stem cells are mesenchymal stem cells,
wherein a molar ratio of the acrylamide monomers and the cross-linking agent is from 150:1 to 1000:1, and
wherein the mesenchymal stem cells are encapsulated in the polyacrylamide hydrogel such that the polyacrylamide hydrogel supports viability and proliferation of the stem cells.
