Cell membrane-coated nanocarriers: the emerging targeted delivery system for cancer theranostics

Area of Science:

• Biomedical Engineering
• Nanotechnology
• Oncology

Background:

• Cancer remains a major global health challenge, driving the need for innovative therapeutic strategies.
• Conventional nanocarriers (NCs) show promise in cancer therapy but often lack specificity and exhibit poor biodistribution, limiting their clinical efficacy.
• Targeted drug delivery is crucial for enhancing therapeutic outcomes and minimizing side effects in cancer treatment.

Purpose of the Study:

• This review explores the preparation, targeting mechanisms, and therapeutic applications of cancer cell membrane-coated nanocarriers (CCMCNCs).
• The aim is to highlight how CCMCNCs address the limitations of conventional NCs in cancer therapy.
• To provide insights into the potential of CCMCNCs for enhanced tumor-specific drug delivery.

Main Methods:

• Discussion of preparation methods for CCMCNCs, focusing on incorporating cancer cell membrane components.
• Analysis of homologous targeting mechanisms inherent to CCMCNCs.
• Review of current applications and case studies of CCMCNCs in preclinical and clinical cancer therapy.

Main Results:

• CCMCNCs demonstrate superior specificity and enhanced intratumoral penetration compared to conventional NCs.
• The cell membrane coating provides robust, cell-specific targeting and extended blood circulation.
• CCMCNCs achieve higher tumor-specific accumulation, leading to improved therapeutic efficacy.

Conclusions:

• CCMCNCs represent a promising advancement in targeted cancer therapy by leveraging cancer cell membrane properties.
• Their ability to target tumors specifically and improve drug accumulation offers a significant advantage over traditional nanocarriers.
• Further research and development of CCMCNCs hold great potential for revolutionizing cancer treatment strategies.
