Abstract: 
Prostate cancer is one of the malignant tumors endangering human life. Multilayered paper-based cell culture, as an in vitro three-dimensional (3D) cell culture method, has been frequently used to research drug bioavailability, therapeutic efficacy and dose-limiting toxicity in malignant tumors. This paper proposes a heterogenous multilayer paper stacking co-culture system to establish a model of natural killer cells (NKs) from the endothelium layer, which attack tumor spheroids. This system consists of three layers: a bottom tumor spheroids layer, a middle invasion layer, and a top endothelium layer. NK-92 cells were placed in the supernatant on top of the three layers. After two days of co-culture, the attack of tumor spheroids by NKs was observed. We additionally examined the infiltration of NK-92 cells within the tumor spheroids at different Z-axis depths using a confocal microscope, and the results suggested that the system successfully realizes NKs traveling cross the endothelium layer to form tumor infiltrating NKs (TINKs). The potential application of multilayered papers for co-culture models involving cancer cells and immune cells holds great promise for exploring the interaction dynamics of these two cell types.
