Rabbit Study of an In Situ Forming Hydrogel Vitreous Substitute

Abstract: The fact that this process of in situ gelation gives rise to hydrogels that are biocompatible and physically and optically similar to the natural vitreous suggests its suitability as a permanent vitreous substitute. Hydrogel candidates will be further studied to evaluate long-term biocompatibility and degradation in vivo.

“…The protocol was as follows: under a dry nitrogen atmosphere, 0.5 g of macromonomer (6) was dissolved in DMF and 5 g of AMPS-Na þ was added. Additionally, DMF (20 mL in total) was added dropwise until a clear homogenous solution was obtained.…”

“…[4,5] Swindle-Reilly et al presented an in situ gelling copolymer hydrogel using disulfide crosslinks formed by air oxidation. [6] Therefore, the design of novel polymers and regarding to those in situ forming systems appears especially attractive. We propose a new concept as a practical consideration for vitreous substitutes, based on thermoresponsive in situ gelation.…”

“…18 There is a type of hydrogel that can undergo sol-gel transformation by inducing an oxidationreduction reaction or a thermal difference, but its use is extremely inconvenient because the hydrogel must be handled in a vacuum or under a controlled temperature immediately prior to injection. 19,20 A self-assembling peptide, SPG-178, spontaneously assembles itself into nanofibers, creating a stable b-sheet structure in water. The fibers then spontaneously build themselves into a three-dimensional mesh net (Fig.…”
