MAP PLATFORM TECHNOLOGY
Microporous Annealed Particle (MAP) gel, invented by Dr. Griffin, is a synthetic injectable material that forms an open pore scaffold in situ, promoting extensive tissue ingrowth and accelerated wound closure. MAP gel is composed of polyethylene glycol (PEG) microspheres that form a solid, open pore scaffold, resulting in a minimal immune response. MAP gel has shown tissue integration due to interconnected microporosity, which can have tunable physical and degradation properties.
Our research focuses on controlling MAP surface chemistry, porosity, and delivery in order to promote tissue integration and regeneration.
Microporous annealed particle scaffolds consist of a slurry of hydrogel microspheres that undergo annealing to form a solid scaffold. We are interested in further optimizing this technology for a variety of clinical uses by exploring new chemistries.
