UCLA researchers have discovered how prostate cancer stem cells evolve as the disease progresses, a finding that could help point the way to more highly targeted therapies. Following recent studies showing that prostate cancer originates in basal stem cells, UCLA researchers were surprised to discover that the cancer eventually begins to grow from a different type of cell called a luminal stem cell. The new discovery indicates that the basal stem cells evolve into luminal stem cells as the cancer grows. Existing prostate cancer drugs are designed to seek out and kill the basal stem cells that give rise to the cancer, so the evolution from basal to luminal stem cells creates a "moving target" that renders the drugs less effective over time.
