EXPANSION OF LUMINAL PROGENITOR CELLS IN THE AGING MOUSE AND HUMAN PROSTATE
In a new study published in Cell Reports, co-first authors Preston Crowell and Jonathan Fox from the Goldstein Lab led a team of researchers at UCLA and UT Southwestern to determine the mechanisms by which aging increases disease risk in the prostate. The group determined that a specific type of progenitor cell (luminal progenitor cell) is increased in the aging mouse and human prostate. The luminal progenitor cells have previously been shown to be able to develop into prostate cancer in response to oncogenic insults, which means that there are more cells at risk for developing into cancer in the aging prostate. Future studies will be aimed at determining what causes the age-related increase in luminal progenitor cells so that we can develop strategies to slow or prevent this process and reduce the risk of disease in the prostate.
