Deep tissue injuries, such as severe burns and volumetric muscle loss result in significant function loss from inadequate tissue regeneration. Current treatment options are not optimal. There is a need for a device to recellularize thick tissue scaffolds to promote tissue regeneration in large tissue injuries. This project was aimed at developing a micro/nanoneedle system capable of delivering precise volumes of cell suspension to decellularized tissue scaffolds at least one centimeter thick. The final device consists of two parts: 30g needles and a cell suspension reservoir attached to a motor-driven syringe pump. Verification and validation testing showed that the device can efficiently deliver cell suspension to decellularized tissue up to one centimeter deep.
