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.
Researchers at the National Institutes of Health Clinical Center (NIHCC) and Northern Arizona University (NAU) seek licensing and/or co-development research collaborations for a wearable, pediatric, robotic exoskeleton that facilitates knee extension during walking to provide motorized movement assistance and training through the gait cycle. The Robotic Exoskeleton is specifically designed for therapy of crouch gait in children with cerebral palsy (CP). The design is a customizable human-machine interface that allows an individualized assistance protocol to help preserve and enhance muscle strength and control. Early clinical results from this intervention appear promising for a condition having few effective long-term interventions.
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.
