CEPCs-Targeted Exosome Modification Service

CEPCs-Targeted Exosome Modification Service enables the engineering of exosomes to specifically recognize and deliver therapeutic molecules to circulating endothelial progenitor cells (CEPCs), offering a novel, efficient, and precise delivery platform for vascular repair, regenerative therapy, and targeted drug delivery.

CEPCs are a cell population with vascular regenerative potential and have been widely applied in the treatment of cardiovascular diseases, vascular repair, and regenerative medicine research. However, conventional delivery methods often fail to achieve precise targeting and efficient delivery, limiting their clinical utility.

Exosomes, nanoscale vesicles secreted by cells, exhibit excellent biocompatibility, stability, and delivery capability. By modifying the exosomal membrane with specific targeting peptides, antibodies, or aptamers, exosomes can be endowed with targeting specificity toward CEPCs. These engineered exosomes can bind to receptors on the CEPC surface, enter the cells via endocytosis, and release their therapeutic cargo, thereby modulating CEPC function and promoting vascular repair and regeneration.

Analysis Workflow

1. Targeting Ligand Design and Screening

Design and screen peptides, antibodies, or aptamers targeting CEPCs based on research needs, ensuring high affinity and specificity.

 

2. Construction of Modified Expression System

Fuse the targeting ligand to exosomal membrane proteins (e.g., Lamp2b, CD63), and establish engineered cell lines for the secretion of targeted exosomes.

 

3. Exosome Isolation and Purification

Exosomes are isolated from the engineered cell culture supernatant using methods such as ultracentrifugation, size-exclusion chromatography (SEC), or immunomagnetic bead separation.

 

4. Functional Molecule Loading (Optional)

Load miRNA, siRNA, proteins, or small-molecule drugs into the exosome interior using electroporation, sonication, or other methods to enhance therapeutic potential.

 

5. Targeting Validation

Evaluate whether the modified exosomes can specifically bind to and be taken up by CEPCs.

 

6. Delivery and Reporting

Provide a comprehensive experimental data report, including modification methods and targeting performance.

FAQ

Q. How to select the right targeting molecule to ensure specific recognition and binding to CEPCs?

Targeting molecules for exosomes are typically ligands that bind specifically to receptors expressed on the surface of CEPCs, such as anti-CD34 antibodies or CXCR4 peptides. These ligands must have high affinity and specificity, and their targeting performance should be validated via flow cytometry, co-culture assays, and other techniques. Selection is based on surface marker profiles of CEPCs, ensuring the exosomes can efficiently recognize and bind to the target cells, thereby enhancing delivery precision.
