PSS-based hydrogels support growth of HUES9 cells in vitro. (a) Schematic of PSS-based hydrogel(s) synthesized by copolymerizing acrylamide with sodium 4-vinyl benzene sulfonate with bisacrylamide as a crosslinking agent. Representative phase contrast images of HUES9 colonies on (b) PAm6-co-PSS2 hydrogel, (c) Matrigel, and (d) mouse embryonic fibroblasts (MEFs) after 7 days in culture in StemPro medium. (e) Population doubling of HUES9 cells over five days of B–D. Scale bar: 200µm. Values are shows as mean ± SD. *** p < 0.001.
