Project Summary Our overall strategy for Hesperos is to utilize microphysiological systems in combination with functional readouts to establish platforms capable of sophisticated analysis of chemicals and drug candidates for toxicity and efficacy during pre clinical testing with initial emphasis on predictive toxicity This is a service based company and is developing low cost in vitro systems utilizing a novel pumpless microphysiological platform described in US Patent B June The compartments each representing a tissue or organ are connected by a serum free medium which mimics the blood The pumpless integrated system using a rocking motion to pump the serum free cellular medium reduces the complexity and cost of the fluidic circuit design and simplifies set up and operation of the device Hickman has developed microelectrode arrays and cantilever systems that are integrated on chip that allows for noninvasive electronic and mechanical readouts We will utilize microfluidic analytical components with this system for rapid and sensitive biomarker chemical protein and small molecule assessment However the number of biomarkers to be monitored for cell health and function will be greatly reduced in our systems from use of the functional readouts We have constructed physiological systems that represent cardiac muscle and liver function that are being used at Hesperos and in Hickman s lab by pharmaceutical and cosmetic companies We have demonstrated multi organ toxicity in the organ system composed of neuronal cardiac liver and muscle components This system is the first microfluidic model to demonstrate the capacity to promote the survival and functional competence of interconnected tissue modules in serum free medium over extended culture periods Further evidence of the commercial viability of our platform is that we have just been awarded a Phase II SBIR grant from National Center for Advancing Translational Sciences NCATS to apply advanced manufacturing techniques to our basic organ platform in collaboration with National Institute of Standards and Technology NIST In this proposal we extend the organ system to include a model of the human kidney as a step toward a more complete ADMETox model Our first aim will be to design fabricate and test a kidney module to model aspects of elimination through the kidney We will then incorporate the kidney module with the existing organ module This requires the addition of another layer to allow flow of a dialysis stream to mimic excretion through the kidney The kidney will have glomerulus and proximal tubule compartments Electrodes to directly measure TEER transepithelial electrical resistance will be integrated into the kidney module The existing system will measure functional readouts of force for skeletal muscle and cardiac and electrical activity of neurons and patterned cardiomyocytes The system will be validated with drugs and chemicals that have shown to effect kidney function Project Narrative Public Health Relevance The overall strategy for Hesperos is to utilize organ on a chip systems and sensors to model the interactions of body organs such as the nervous system circulatory system and kidney and offer this as a service to pharmacology companies who seek analysis of potential drug candidates This system can be utilized in drug discovery and toxicity studies and shows potential of decreasing the cost of the drug development process which should lead to less expensive drugs for the public at large
