Customization Services for Paracrine Senescent Cells


It has been known that senescence-associated secretory phenotype (SASP) triggers senescence of the surrounding normal cells. SASP involves the secretion of various pro-inflammatory cytokines, chemokines, growth factors, and matrix-remodeling enzymes by senescent cells. This creates an inflammatory microenvironment that can induce senescence in neighboring normal cells through paracrine signaling.

At CD BioSciences, we offer a range of services focused on the customization of paracrine senescent cells. Our services provide researchers with the tools and resources necessary to investigate the effects of senescent cells on neighboring cells in vitro. By utilizing our expertise and techniques, clients can gain valuable insights into the molecular mechanisms, signaling pathways, and therapeutic interventions associated with paracrine cellular senescence.

Modeling Methods for Paracrine Senescent Cells

Influenza virus-induced paracrine cellular senescence

Influenza viruses are known to induce cellular senescence in host cells as a defense mechanism. Our team of experts can design and customize in vitro models to mimic this paracrine senescence phenomenon. We initiate the model by infecting the selected cell lines with the influenza virus at an appropriate multiplicity of infection at a specific time point. This step aims to induce viral infection in the host cells, triggering subsequent senescence-related responses. Our services allow clients to investigate the molecular changes and immunomodulatory effects associated with influenza-induced senescence.

Stromal cell-induced paracrine cellular senescence

Another area of expertise in our paracrine cellular senescence model customization services revolves around stromal cell-induced senescence. Our team specializes in establishing co-culture systems, where senescent cells and neighboring cells are cultured together. Our services setup mimics the paracrine communication between senescent cells and their surrounding microenvironment. We help clients construct customized in vitro models that incorporate stromal cells and senescent cells.

How Do We Customize Paracrine Senescent Cells?

CD BioSciences follows a meticulous workflow to construct highly customized paracrine senescent cells. This streamlined process ensures the delivery of reliable models that meet the specific requirements of our clients.

  • Project consultation. Our team of experts engages in comprehensive discussions with clients to understand their research goals, experimental design, and specific senescence-related questions. The initial step allows us to tailor the model construction process to the unique needs of each project.
  • Cell selection and characterization. Based on the project requirements, we carefully select appropriate cell types that exhibit paracrine senescence characteristics. We perform a thorough characterization of these cells to ensure their SASP and other relevant markers are in line with the desired model.
  • Model construction. We support model customization services using a variety of methods, including but not limited to influenza virus and stromal cell induction. Our services help clients to design co-culture models to mimic the paracrine effects of senescent cells on neighboring cells by co-culturing infected cells with uninfected cells, and senescent cells and their surrounding microenvironment.
  • Validation and quality control. Once the paracrine senescent cells are constructed, we rigorously validate their functionality and reliability. We assess key senescence markers, secretory profiles, and other relevant parameters to ensure accurate representation and reproducibility of the desired senescence model.
  • Data analysis and reporting. We provide robust data analysis and interpretation services. Additionally, we deliver detailed reports summarizing the findings and their implications in the context of the specific research objectives.

Through a well-defined workflow and leveraging our scientific expertise and technologies, CD BioSciences provides tailored solutions to construct paracrine senescent cells. If you are interested in our services, please feel free to contact us or make an online inquiry.
