3D Co-culture System of Mouse Prostatic Wild-type Fibroblasts withHuman Prostate Cancer Epithelial Cells.

Abstract

Heterogeneous prostatic carcinoma-associated fibroblasts (CAF) contribute to tumor progression. This was established using transgenic mouse models. Paracrine interactions between fibroblasts and epithelial cells were further interrogated using isolated 2D cell culture systems, but 3D culture systems currently being developed can better mimic reciprocal interactions potentially found in the native tissue. To understand paracrine and juxtacrine signaling among fibroblasts and epithelia, 3D co-cultures with species differences allows for further subsequent analysis of the cultures. The use of mouse and human cells, for example, in one system allows for species-specific FACS or quantitative PCR analysis. This protocol describes the use of a 3D Co-culture System of Mouse Prostatic Wild-type Fibroblasts with Human Prostate Cancer Epithelial Cells.
