Abstract:

The incidence of chronic kidney disease (CKD) continues to increase globally and progresses to end-stage renal disease (ESRD) . For patients with ESRD, dialysis or kidney transplantation has always been the leading clinical treatment. However, dialysis treatment is associated with several complications and limits a patient's lifestyle and social activities. Kidney transplantation is another viable treatment option for ESRD but is limited due to issues such as donor shortage and rejection. Therefore, many strategies for kidney regeneration are under investigation. As a tissue engineering technology, 3D bioprinting has made progress in fabricating in vitro kidney tissue models and kidney-like structures. It is expected to solve the problem of organ donor shortage by creating artificial organs/tissues. While the technology has been adapted to a variety of cell types and biomaterials, many issues still need to be addressed. Examples include cell and biomaterial selection and simulating vascular networks. This article aims to review the latest progress of 3D bioprinting in the field of kidney regeneration, including commonly used 3D bioprinting technologies and biomaterial selection, 3D bioprinting to generate partial nephrons, and challenges and future development directions.

Key words: 3D bioprinting, Bioink, Kidney cells, Induced pluripotent stem cells
