| Title |
Normal human prostate (NHP) epithelial cells: Senescent and immortalized cells compared to young progenitors |
| Organism |
Homo sapiens |
| Experiment type |
Expression profiling by array

| Summary |
Normal human prostate (NHP) epithelial cells undergo senescence in vitro and in vivo, but the underlying molecular mechanisms remain incompletely understood. Here we first show that multiple primary strains of NHP cells are all immunophenotyped as CK5+/CK18+CD44+α2β1+p63+hTERT+ progenitor cells, which gradually lose progenitor markers as they lose proliferative capacity. NHP cell senescence involves loss of telomerase expression, upregulation of p16, and activation of p53. Using genetically defined manipulations of these three signaling pathways, we show that p16 is the primary determinant of the NHP cell proliferative capacity and hTERT is required for unlimited proliferative lifespan. Hence, suppression of 16 alone significantly extends NHP cell lifespan but both p16 inhibition and hTERT are required to immortalize NHP cells. Importantly, the immortalized NHP cells are normal progenitors that possess the ability to differentiate into functional prostatic glands containing both basal and luminal cells and, frequently, neuroendocrine cells. The immortalized NHP cells possess gene expression profiles characteristic of proliferating progenitor cells. Our studies shed light on the molecular mechanisms regulating the proliferative lifespan of NHP progenitor cells and provide direct evidence that basal-like progenitor cells can regenerate the entire prostatic glands in vivo. The availability of these cells should facilitate future studies of prostate cancer development.

| Overall design |
Total 7 sets of two color arrays with 3 technical replicates in each set (total 21 individual arrays) were performed and each individual array included a test sample (experimental condition) and a control (young NHP progenitors) sample.
