FIG. 4.
Presence of side population in WT and Abcg2 null prostate cells. (A) Lin− side population of WT ventral prostate is 0.7% of total Lin− cells, while Lin+ side population is 5.2% of total Lin− cells in a representative experiment. Experiment was performed thrice. (B) Population hierarchy statistics generated by BDFACS Diva software showing Scahigh (56.4%) and CD44high (35.1%) cells in Lin− side population from WT ventral prostate. (C) Elimination of Lin− side population from WT ventral prostate with 1 μM reversan treatment. (D) Lin− side population in Abcg2 null ventral prostate cells. (E) Elimination of Abcg2 null Lin− side population with 1 μM reversan treatment. Color images available online at www.liebertpub.com/scd
