The tumour microenvironment plays a vital role in the development of solid malignancies. Here we describe an in vitro human prostate cancer microtissue model that facilitates the incorporation and interrogation of key elements of the local prostatic tumour microenvironment. Primary patient-derived cancer-associated fibroblasts (CAFs) were cultured in three-dimensional (3D) melt electrowritten scaffolds where they deposited extensive extracellular matrix (ECM) and promoted significant changes in prostate epithelial morphology, when compared to matched non-malignant prostatic fibroblasts (NPFs). The addition of mast cells, a resident prostatic immune population that is expanded during early ma..
