The Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD) seeks research and development partners or licensees for novel composite hydrogels that can be used in tissue repair and other applications. Single gel networks used in tissue engineering and tissue repair applications generally become softer and more flaccid as they swell. The gels described in this technology, however, which comprise a swellable crosslinked polymer hydrogel dispersed in a crosslinked polymer matrix, mimic critical material properties of tissue extracellular matrix (ECM), for instance, becoming stiffer and tougher upon swelling.
Researchers at the National Eye Institute (NEI), have developed a cryopreservation and cell recovery system designed specifically for the efficient cryopreservation, transportation and subsequent thawing of monolayers and tissues on a substrate. This closed cryopreservation/defrost system allows for sterility in addition to increased viability, recovery and safety of tissues that can be used for in vitro culture or surgical transplantation.
Surgery specialists from Johns Hopkins University, in collaboration with researchers at the National Cancer Institute (NCI), developed peptide hydrogel compositions and methods to suture blood vessels during microsurgery. The hydrogels particularly benefit surgeons in whole tissue transplant procedures. The NCI seeks co-development research collaborations for further development of this technology.
