UC San Diego secured an ARPA‑H Personalized Regenerative Immunocompetent Nanotechnology Tissue (PRINT) award to develop patient‑specific, 3D‑bioprinted human livers, receiving up to $25.77 million for a 60‑month project. The multidisciplinary effort will combine rapid high‑resolution bioprinting, patient‑derived cells, vascular engineering and AI‑driven design to create transplantable liver tissue and reduce reliance on donor organs. Project leaders at UCSD described capabilities to fabricate complex, multi‑cellular vascular networks and to integrate AI for design and scale‑up. The award places the work within ARPA‑H’s push to accelerate high‑risk, high‑reward regenerative solutions and positions the team to generate data to support future clinical translation and regulatory interactions.
