Drug Delivery Systems Using Surface Markers for Targeting Cancer Stem Cells

Area of Science:

• Oncology
• Nanomedicine
• Cancer Biology

Background:

• Cancer stem cells (CSCs) possess inherent resistance to chemotherapy and radiation.
• CSCs drive tumor aggressiveness, relapse, and metastasis.
• Targeting CSCs is crucial for effective cancer treatment.

Purpose of the Study:

• To review surface markers that identify CSC populations across various cancers.
• To discuss novel nanomedicine-based strategies for targeting CSCs and their niches.

Main Methods:

• Literature review of CSC surface markers.
• Analysis of nanomedicine delivery systems (liposomes, nanoparticles, carbon nanotubes, viral vectors).

Main Results:

• CSCs are identified by diverse surface markers.
• Nanomedicine formulations show promise for targeted CSC elimination.
• Targeting CSC niches alongside CSCs is a developing strategy.

Conclusions:

• Specific CSC surface markers can be targeted using advanced nanomedicine.
• Targeted delivery systems offer a promising approach to overcome chemoresistance.
• Eliminating CSCs is key to preventing tumor recurrence and metastasis.
