Luminal cell and basal cell representation in prostate cDNA libraries: The luminal and basal cell genes are placed by their cluster ID number. The various cDNA libraries are identified on the top of the grid pattern. Presence in a particular library is indicated by colored boxes: black for normal, rose for PIN, red for primary carcinoma, light orange for primary carcinoma invasive, blue for metastatis, lavender for xenografts and cancer cell lines, and lime for cultured cells.

This figure was derived from data in the PEDB (Prostate Expression DataBase).
