Links between cancer stem cells and epithelial-mesenchymal transition

Area of Science:

• Oncology
• Cell Biology
• Cancer Research

Background:

• The epithelial-mesenchymal transition (EMT) is a key process in cancer invasion and metastasis.
• Cancer stem cells (CSCs) initiate and maintain tumors, also contributing to metastasis.
• Mesenchymal cells, including some CSCs, exhibit self-renewal properties.

Purpose of the Study:

• To review the molecular mechanisms linking EMT and CSCs in cancer progression.
• To elucidate how EMT contributes to the metastatic potential of CSCs.
• To understand the role of CSC self-renewal in cancer metastasis.

Main Methods:

• Literature review of studies on EMT and CSCs.
• Analysis of molecular pathways connecting EMT and CSC characteristics.
• Synthesis of current research on EMT-CSC interactions in cancer metastasis.

Main Results:

• EMT confers CSC properties, enhancing self-renewal and metastatic potential.
• A subset of EMT-activated cells possess CSC traits crucial for distant organ colonization.
• Specific molecular mechanisms underpin the interplay between EMT and CSCs.

Conclusions:

• The EMT program is intrinsically linked to CSC biology and cancer metastasis.
• Targeting the EMT-CSC axis presents a potential therapeutic strategy for advanced cancers.
• Further research into the molecular dialogue between EMT and CSCs is warranted.
