Changes in rheological behavior of hydrogels following in situ gelation modeling with a normal (1.8 mM) Ca²⁺ concentration. Strain sweeps demonstrating the effect of incubation in Ca²⁺ containing media on (A) A25/C0/G0/Ca22, (B) A25/C125/G1/Ca23, (C) A25/C25/G05/Ca18, (D) A5/C0/G0/Ca22, (E) A5/C125/G1/Ca24, and (F) A5/C25/G01/Ca20 hydrogels. n = 3, mean ± standard deviation. (* denotes significance between day 0 and day 2. + denotes significance between day 0 and day 5. # denotes significance between day 2 and day 5.)
