Objectives
1. To characterise the morphometric and physiological parameters of a NPC tumour based on anatomy of tumour biopsies for the design of a 3D biomimetic microsystem. 2. To establish a 3D cell culture microsystem as a realistic mimicry of a tumour, in particular human NPC, based on the morphometric data obtained in Objective 1, with cancer cells and stromal fibroblasts infiltrated by tubules with endothelial cells that resemble blood capillaries, through the development of advanced reversal nanoimprint and nanotechnology, novel materials, sensors, and multiple fluidic control elements with precise positioning and movement of cells, molecules, and chemicals. 3. To validate the 3D microsystem developed in Objective 2 as a biomimetic tumour model by comparing cancer cell growth kinetics obtained from the 3D engineered platform with xenograft NPC tumours and to further optimise the design of the 3D bioreactor. 4. To build quantitative models on tumour survival, proliferation, and drug responses by systematically comparing the effect of cell ratio, supply of oxygen, chemicals, and cytotoxic drug in the 3D microsystem optimised in Objective 3.
