Table 1 Viable ALDH Hi , ALDH Low , side population and non-side population cells in human prostate tissue specimens

From: Aldehyde dehydrogenase and ATP binding cassette transporter G2 (ABCG2) functional assays isolate different populations of prostate stem cells where ABCG2 function selects for cells with increased stem cell activity
