Humanizing Miniature Hearts through 4-Flow Cannulation Perfusion Decellularization and Recellularization
Abstract Despite improvements in pre-clinical drug testing models, predictability of clinical outcomes continues to be inadequate and costly due to poor evidence of drug metabolism. Humanized miniature organs integrating decellularized rodent organs with tissue specific cells are translational model...
