This project focuses on the development of a reproducible human omentum model using three-dimensional (3D) bioprinting technology, which allows spatially controlled deposition of cells and biomaterials in an automated process. We aim to mimic the defined structure of the human omentum and evaluate its capacity to simulate the in vivo condition both in healthy and diseased states. Additionally,visualization and characterization to investigate adhesion and migration property of cancer cells into this 3D human omentum tissue is envisaged.
