IOP Publishing Aug 12 2025 Scientists at Tsinghua University have developed a method to grow kidney tumors in the lab using cells from real patients, offering a potential new tool in the fight against renal cancer. Their research, published in the journal  Biofabrication , outlines how 3D bioprinting technology can be used to replicate the unique characteristics of each patient's tumor. The team combined tumor cells with other cell types, including blood vessel-like structures, to mimic the
