Summary
Prostate cancers have diverse cells, with low prostate-specific antigen (PSA) cells showing tumor-initiating potential. These cells may drive resistance to androgen-deprivation therapies in prostate cancer patients.
Area of Science:
- Oncology
- Stem Cell Biology
- Urology
Background:
- Human prostate cancers exhibit cellular heterogeneity, with varying levels of prostate-specific antigen (PSA) expression.
- Prostate-specific antigen (PSA) is a key differentiation marker in the prostate gland.
Discussion:
- The study identifies distinct cell populations within human prostate cancers based on PSA expression levels.
- PSA expression levels correlate with cellular characteristics and potential roles in cancer progression.
Key Insights:
- Prostate cancer cells with low or undetectable PSA (PSA(-/lo)) possess tumor-initiating capabilities.
- These PSA(-/lo) cells may be crucial in the development of resistance to androgen-ablative therapies.
Outlook:
- Further research into PSA(-/lo) cells could reveal new therapeutic targets for overcoming treatment resistance.
- Understanding cellular heterogeneity in prostate cancer is vital for developing more effective treatment strategies.

Cancer Stem Cells and Tumor Maintenance
Early diagnosis and treatment can often cure cancer. However, even with treatment, residual cells called cancer stem cells (CSC) might remain, often causing tumor recurrence. These cancer stem cells possess the potential for self-renewal and multi-lineage differentiation and are often responsible for the therapeutic resistance displayed in most cancers.
Cancer stem cells are thought to originate from tissue-specific normal stem cells or progenitor cells. The normal stem cells usually reside in...

Distinctive Features of Adult Stem Cells vs Cancer Stem Cells
A stem cell is an unspecialized cell that can divide without limit as needed and can, under specific conditions, differentiate into specialized cells.
Adult stem cells
Adult stem cells are tissue-specific; hence, they divide to develop the tissue from which they originate. One type of adult stem cell is the epithelial stem cell, which gives rise to the keratinocytes in the multiple layers of epithelial cells in the epidermis of the skin. Adult bone marrow has three distinct types of stem cells:...

Adult Stem Cells
Stem cells are undifferentiated cells that divide and produce more stem cells or progenitor cells that differentiate into mature, specialized cell types. All the cells in the body are generated from stem cells in the early embryo, but small populations of stem cells are also present in many adult tissues including the bone marrow, brain, skin, and gut. These adult stem cells typically produce the various cell types found in that tissue—to replace cells that are damaged or to continuously renew...
