Abstract: A hydrogel material for use in a human subject or other mammal includes a collection of microgel particles having one or more network cross linker components, wherein the microgel particles, when exposed to an endogenous or exogenous annealing agent, links the microgel particles together in situ to form a covalently-stabilized scaffold of microgel particles having pores formed between the microgel particles wherein the pores are substantially devoid of hydrogel.

Abstract: A microporous gel system for certain applications, including biomedical applications, includes an aqueous solution containing plurality of microgel particles including a biodegradable crosslinker. In some aspects, the microgel particles act as gel building blocks that anneal to one another to form a covalently-stabilized scaffold of microgel particles having interstitial spaces therein. In certain aspects, annealing of the microgel particles occurs after exposure to an annealing agent that is endogenously present or exogenously added. In some embodiments, annealing of the microgel particles requires the presence of an initiator such as exposure to light. In particular embodiments, the chemical and physical properties of the gel building blocks can be controlled to allow downstream control of the resulting assembled scaffold. In one or more embodiments, cells are able to quickly infiltrate the interstitial spaces of the assembled scaffold.

Abstract: Disclosed herein are therapeutic polymer gel systems for promoting healing of a wound or surgical site in a subject. The therapeutic polymer gel forms a microporous network and may be applied or injected in a fluid form and annealed or crosslinked after application to the wound or surgical site. The microporous gel may optionally contain various therapeutic agents throughout the therapeutic polymer gel which are released.
