Cross-linking collagen with 8S-StarPEG decreased rate of glioma cell-mediated collagen hydrogel degradation. Glioma cells grown in collagen hydrogels cross-linked with different amounts of 8S-StarPEG. *p < 0.05, compared with collagen hydrogels with tumor cell growth at same time point. #p < 0.05, compared with non-crosslinked collagen hydrogels and hydrogels crosslinked with 0.5 mM 8S-StarPEG at same time point. ^p < 0.05, compared with non-crosslinked collagen hydrogels at same time point.
