Abstract:
Major limitations in the effective treatment of neurological cancer include systemic cytotoxicity of chemotherapy, inaccessibility, and inoperability. The capability to successfully target a drug to the tumor site(s) without incurring serious side effects-especially in the case of aggressive tumors, such as glioblastoma and neuroblastoma-would represent a significant breakthrough in therapy. Orthotopic systems, capable of storing and releasing proteins over a prolonged period at the site of a tumor, that utilize nanoparticles, liposomes, and hydrogels have been proposed. One candidate for drug delivery is Micro-Fragmented Adipose Tissue (MFAT). Easily obtained from the patient by abdominal subcutaneous liposuction (autologous), and with a high content of Mesenchymal Stem Cells (MSCs), mechanically derived nanofat is a natural tissue graft with a structural scaffold organization. It has a well-preserved stromal vascular fraction and a prolonged capacity to secrete anti-tumorigenic concentrations of pre-absorbed chemotherapeutics within extracellular vesicles. This review discusses current evidence supporting the potential of drug-modified MFAT for the treatment of neurological cancer with respect to recent preclinical and in vitro studies. Possible limitations and future perspectives are considered.
Insights
Micro-Fragmented Adipose Tissue (MFAT) shows promise for delivering chemotherapy directly to neurological cancer sites. This autologous tissue graft, rich in Mesenchymal Stem Cells (MSCs), can store and release anti-tumor drugs, minimizing systemic side effects.
Area of Science:
- Biomedical Engineering
- Oncology
- Regenerative Medicine
Background:
- Neurological cancer treatment faces challenges like chemotherapy's systemic toxicity and tumor inaccessibility.
- Targeted drug delivery to brain tumors (e.g., glioblastoma, neuroblastoma) is crucial for improved efficacy and reduced side effects.
- Existing drug delivery systems (nanoparticles, liposomes, hydrogels) have limitations.
Purpose of the Study:
- To review the potential of drug-modified Micro-Fragmented Adipose Tissue (MFAT) for treating neurological cancers.
- To evaluate MFAT as an orthotopic drug delivery system utilizing its inherent properties.
- To discuss preclinical and in vitro evidence supporting MFAT's therapeutic application.
Main Methods:
- Review of current preclinical and in vitro studies on MFAT for neurological cancer.
- Analysis of MFAT's composition, including Mesenchymal Stem Cells (MSCs) and stromal vascular fraction.
- Evaluation of MFAT's capacity for prolonged drug storage and release via extracellular vesicles.
Main Results:
- MFAT, an autologous tissue graft, possesses a natural scaffold structure and high MSC content.
- Mechanically derived nanofat (MFAT) can store and release pre-absorbed chemotherapeutics in anti-tumorigenic concentrations.
- Extracellular vesicles within MFAT contribute to sustained drug delivery at the tumor site.
Conclusions:
- Drug-modified MFAT presents a promising strategy for targeted neurological cancer therapy.
- MFAT's autologous nature and MSC content offer a biocompatible and potentially effective drug delivery platform.
- Further research into MFAT's limitations and future applications is warranted for clinical translation.
