Certain conditions, including inflammation and cancer, require augmentation of the urinary bladder. However, the conventional approach of using bowel tissue suffers from risks and post-surgery complications.
UroPrint proposes the use of Laser-Induced Forward Transfer (LIFT) to generate bladder tissue for autologous transplantation that would meet the biological, mechanical and functional properties of the human bladder. To this end, primary urothelial and smooth muscle cells will be obtained from healthy donors and expanded in fully Good Medical Practice compliant methodologies. These will be combined with novel natural autologous scaffold material obtained from platelet lysates. Then, a novel approach in the generation of bladder transplant will be utilized, combining intestine denudation and in vivo printing during surgery using a novel prototype LIFT printer that achieved high spatial resolution (<10 μm), high cell viability (>95%) single-urothelial cells.
