Cells-Based Drug Delivery for Cancer Applications

Area of Science:

• Biomedical Engineering
• Oncology
• Drug Delivery Systems

Background:

• Cell-based drug delivery systems offer significant advantages in antitumor therapy, including reduced systemic toxicity and enhanced drug penetration to tumor cells.
• Various cell types, such as erythrocytes, white blood cells, platelets, immune cells, and tumor cells, are being investigated for their potential to encapsulate chemotherapy drugs.
• Recent advancements have diversified cell-based vectors to include photosensitizers, enabling combined chemotherapy, photothermal, and photodynamic therapies for enhanced antitumor effects.

Purpose of the Study:

• To review the latest developments in cell-derived drug delivery systems for cancer therapy.
• To highlight the potential of cell encapsulation for improving chemotherapy efficacy and targeting.
• To discuss the challenges and future prospects of translating these technologies into clinical practice.

Main Methods:

• Review of existing literature on cell-based drug delivery systems in cancer therapy.
• Analysis of studies utilizing different cell types for drug encapsulation.
• Examination of combined therapeutic approaches involving chemotherapy, photothermal, and photodynamic therapies.

Main Results:

• Cell encapsulation of chemotherapy drugs demonstrates superior antitumor effects compared to conventional chemotherapy alone.
• Cell-based vectors can be engineered to deliver both chemotherapeutic agents and photosensitizers, facilitating multi-modal cancer treatment.
• Coordinated treatment strategies using cell-based systems show promise against multidrug-resistant and metastatic tumors.

Conclusions:

• Cell-derived drug delivery systems hold great potential for future clinical applications in oncology due to their targeted delivery and reduced toxicity.
• Significant challenges, including the preservation of drug-loaded cells and safe in vivo administration, must be addressed for successful clinical translation.
• Further research and standardization are required to overcome current limitations and realize the full clinical potential of this innovative therapeutic approach.
