Cancer Stem Cells and Tumor Maintenance

4.3K
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

3.8K
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

27.8K
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...

Stem Cell Therapy for Tissue Regeneration

3.8K
Stem cell therapy is a method used in regenerative medicine to repair and restore function to damaged tissues and organs. Stem cells have the potential to proliferate and differentiate into various tissue types, making them ideal candidates for tissue regeneration. For example, hematopoietic stem cell transplants are commonly used in blood cancer treatment to replenish damaged bone marrow and restore healthy blood cells.

Mesenchymal Stem Cells01:19

Mesenchymal Stem Cells

4.5K
Mesenchymal stem cells (MSCs) are adult stem cells that can differentiate into most connective tissue cell types, except for hematopoietic cells, depending upon the source of MSCs. For example, bone-marrow-derived MSCs (BM-MSCs) can differentiate into osteocytes, hepatocytes, and pancreatic and neuronal cells. MSCs can be isolated from various sources such as bone marrow, placenta, adipose tissue, teeth, and Wharton’s jelly, a gelatinous substance in the umbilical cord. The ease of their...

Area of Science:

  • Oncology
  • Stem Cell Biology

Background:

  • The Cancer Stem Cell (CSC) hypothesis posits that a small cell population initiates and drives cancer progression.
  • CSCs are implicated in various solid tumors, including prostate cancer (PCa), potentially explaining treatment failures.
  • CSCs share properties with normal stem cells, making their study crucial for understanding cancer pathomechanisms.

Purpose of the Study:

  • To review existing data on Cancer Stem Cells (CSCs) in prostate cancer (PCa).
  • To explore putative phenotypic markers, the role in tumor biology, and therapeutic relevance of PCa CSCs.

Main Methods:

  • Literature review of existing data on CSCs in prostate cancer.
  • Analysis of studies focusing on CSC phenotypic markers and their biological roles.
  • Examination of therapeutic implications and strategies related to CSCs in PCa.

Main Results:

  • CSCs are proposed as the key drivers of tumorigenesis in a hierarchical model, distinct from stochastic or clonal evolution.
  • The existence of CSCs in PCa may explain the ineffectiveness of current therapies.
  • Understanding normal stem cell biology can illuminate CSC pathomechanisms and therapeutic targets.

Conclusions:

  • CSCs play a critical role in prostate cancer initiation, progression, and therapeutic resistance.
  • Further research into CSC markers and biology is essential for developing targeted therapies.
  • Investigating the link between normal and cancer stem cells offers promising avenues for novel PCa treatments.
