Tissue Exosome Related Therapeutic Research Service

Tissue-derived exosomes are extracellular vesicles extracted from specific tissues such as tumors, neural tissue, or liver. With a typical diameter of 30–150 nm, they are enriched with proteins, lipids, RNAs (mRNA, miRNA), and metabolites that reflect the molecular characteristics of their tissue of origin. These exosomes play vital roles in intercellular communication, signal transduction, immune regulation, inflammation control, tissue repair, and regeneration.

 

Recent studies have highlighted the critical regulatory functions of tissue-derived exosomes in the progression of various diseases. For instance, tumor-derived exosomes can promote cancer cell metastasis, immune evasion, and therapy resistance. Neural tissue exosomes contribute to neuronal signaling and repair, while liver-derived exosomes are involved in inflammation and fibrosis. Therefore, isolating and analyzing exosomes from tissue samples offers valuable insights into disease mechanisms and presents a foundation for developing novel therapeutic strategies and biomarkers.

Tissue-derived exosomes are also gaining recognition as a promising therapeutic modality. By profiling the molecular composition and functional roles of these exosomes, and investigating their interaction with target cells, researchers can design precise and targeted treatment strategies. This approach is particularly beneficial for diseases that are difficult to treat with conventional therapies, including neurodegenerative disorders, malignancies, and chronic inflammatory conditions.

 

Services at MtoZ Biolabs

MtoZ Biolabs provides a Tissue Exosome Related Therapeutic Research Service designed to systematically explore the therapeutic potential of tissue-derived exosomes through high-purity isolation, advanced omics profiling, and in vivo functional validation. This service is tailored for researchers and drug developers working in oncology, neurology, immunology, and fibrosis research. Our aim is to uncover exosome-mediated molecular mechanisms and facilitate the discovery of biomarkers and cell-free therapeutic strategies.

 

We offer the following services:

1. Standardized isolation and purification of tissue-derived exosomes  

2. Exosome size and morphology analysis (TEM/NTA)  

3. Integrated omics analysis: proteomics, miRNA/mRNA transcriptomics, lipidomics, metabolomics  

4. Functional evaluation of exosomal delivery (cellular uptake and behavior assays)  

5. In vivo model validation (biodistribution, therapeutic function, toxicity assessment)  

6. Biomarker discovery and clinical relevance evaluation  

7. Research reporting and data interpretation support  

 

Analysis Workflow

1. Sample Preparation and Preprocessing  

Clients may provide frozen or fresh tissue specimens. MtoZ Biolabs implements standardized sample processing to preserve exosome integrity.

 

2. Efficient Extraction and Purification  

We use differential centrifugation, ultracentrifugation, membrane filtration, and size exclusion chromatography to obtain high-purity exosomes with minimal contamination.

 

3. Multidimensional Characterization  

Morphological and marker-based validation using transmission electron microscopy (TEM), nanoparticle tracking analysis (NTA), and Western blotting (CD63, TSG101, Alix).

 

4. Functional Omics Profiling  

Comprehensive molecular profiling through proteomics, miRNA/mRNA sequencing, lipidomics, and metabolomics to generate detailed exosomal signatures.

 

5. In Vitro and In Vivo Functional Validation (Optional)  

Evaluation of biological effects via cellular assays (uptake, inflammation, repair) and animal models for distribution, efficacy, and safety.

 

6. Biomarker and Therapeutic Molecule Discovery  

Based on omics data, we identify candidate molecules for therapeutic development and provide translational insights for future applications.
