Cell viability in response to glutaraldehyde used for crosslinking of the hydrogels. Cells were plated onto unloaded (no protein added) hydrogels crosslinked with various concentrations of glutaraldehyde. Glutaraldehyde concentration did not appear to affect cellular viability/proliferation using bright field inverted microscopy. 10× magnification.
