Degradation and release dynamics of LLC hydrogel. (A) Sequential images of vials containing the LLC hydrogel formulation on days 1, 4, 7, 14, 21, 28, 42, and 60, visually demonstrating the gradual degradation and structural changes of the hydrogel matrix over time. (B) A degradation curve showing the percentage of hydrogel degradation at each of these time points, clearly illustrating the reduction in structural integrity over the 60-day period. (C) Release profile of SDF-1α from the LLC hydrogel over specific time intervals (1, 2, 4, 6, 24, 48, 72, and 144 h), demonstrating a sustained and controlled release pattern essential for the effective delivery of the bioactive compound.
