Abstract

In this video, we demonstrate the culturing of isolated mouse prostate epithelial cells using a matrix gel-ring based culture technique. This approach can provide complementary information about the differentiation capacity of prostate epithelial cells to form 3D glandular structures in response to genetic or pharmacological manipulation.
Protocol
1. Plating Sorted Prostate Epithelial Cells into Primary Mouse Organoid Culture — TIMING: 2-3 H (Excluding Poly-HEMA-coated Plate Preparation) NOTE: Plates are coated with Poly-HEMA to prevent 2D colony formation on the surface of the well beneath the matrix gel. Prepare Poly-HEMA-coated plates 1 day prior to plating sorted basal or luminal prostate epithelial cells into mouse organoid culture. Thaw 1 mL aliquots of reduced growth factor matrix …
