Single-cell proteomics involves the qualitative and quantitative analysis of protein expression profiles at the single-cell level, enabling researchers to study the protein landscape of individual cell subpopulations. Several advanced techniques are now available for single-cell proteome analysis, including antibody-based single-cell mass cytometry, cytokine panel detection for single-cell functional protein analysis, and TMT-labeled spectrum technology for single-cell protein quantification. These methods allow for the clustering of cell subpopulations based on their unique protein expression profiles at various scales.
Among the cargo carried by exosomes, proteins play a critical role as signaling molecules, directly participating in the regulation of various biological pathways and influencing the function of recipient cells. Recent studies have identified potential donor cells for tissue-derived exosomes using single-cell and exosome transcriptomics, proposing a potential mechanism for tissue exosome transport. Similarly, the advent of single-cell proteomics provides a more precise approach to tracing the origins and communication pathways of tissue exosomes at the protein level.
Combined proteomics research, which integrates single-cell and tissue exosome analyses, is poised to significantly advance our understanding of the protein-mediated mechanisms behind exosome-driven biological phenomena. This comprehensive approach will help researchers achieve high-quality, in-depth insights and produce high-impact research outcomes.
At Creative Biolabs, we offer efficient tissue permeabilization techniques for isolating both cell and exosome collections. By leveraging the most appropriate single-cell and exosome proteomics technologies, we assist clients in identifying the parent cell types responsible for producing key proteins found in exosomes.
