Research Topics


CyFlow is a facility devoted to cellular analysis through flow cytometry and other technological approaches. Multi-parametric cell phenotyping and multi-parametric cell sorting including single cell sorting can be performed using various equipment. To meet the growing need for high throughput single cell analysis, the facility will also soon provide nanofluidic single cell partitioning for omics studies. CyFlow is located in the research building of the Faculty of Medicine and Pharmacy in Rouen. It is open to academic and nonacademic researchers. Depending on their need and their basic knowledge, access to the facility is offered either as “autonomous users” after training, “scientific collaborators” or “customers (request of service)”. Access to the facility is dependent on the biosafety levels of the samples. Application form is available by contacting gaetan.riou@inserm.fr.

Facilities


INSTRUMENTS FOR ANALYSIS:
FACSCanto (BD Bioscience): 2-laser fully digital analyzer with up to 6-color simultaneous analysis,  equipped with a carrousel loader for automated analysis of 40 tubes. CytoFlex(Beckman Coulter): 2-laser fully digital analyzer with up to 4-color simultaneous analysis, with capacity for microparticule detection (down to 200 nm). LSRFortessa(BD Bioscience): This analyzer is a sophisticated analytical instrument, used for multiparametric analysis of cell samples. It is equipped with five lasers and is theoretically capable of up to 18-color analysis (in practice, 12-color simultaneous analysis).   INSTRUMENT FOR CELL SORTING:
FACSAria-IIIu(BD Bioscience): This fully digital high-speed cell sorter is used for sorting of cell samples based on multiple phenotypic parameters. Equipped with 4 lasers and capable of up to 12-color simultaneous analysis, it can also be used for single cell cloning in 96-well plates.


Activity


Main activities

CyFlow offers the use of different multi-parametric flow cytometry analyzers and one high-speed FACS cell sorter.  The technical characteristics and advantages of each of these apparatus are described above. CyFlow equipment may be used for the following applications and studies:
  • Cell immuno-phenotyping with the simultaneous measurement of up to 12 fluorescence parameters
  • DNA content, ploidy and cell cycle analysis
  • Assessment of apoptosis and cell death
  • Cellular functional studies (calcium flux, oxidative burst, cell proliferation)
  • Multiplexed and micro-particle-based analysis (fluorescence bead arrays)
  • Detection of microparticule (down to 200 nm such as bacterias, yeasts, microalgae…)
  • Molecularcytogenetics
    • Micro-biological applications (detection of heterogeneous microbial population using nucleic acid probes, evaluation of sensitivity/resistance to drug)
  • Cell sorting based on the simultaneous analysis of up to 12 fluorescence parameters at high speed (20,000 cells per second) and high purity (>95% purity)
  • Single-cell flow cloning in 96-well plates for cell culture and molecular biology applications
The facility is also extending its activities to cell analysisusing other approaches than flow cytometry. It will soon provide a nanofluidic technology for single cell omics analysis.

Complementary activities

 The following activities can be provided on demand:
  • Consulting in flow cytometry technologies and multiparametric cell sorting
  • Training and education
  • Scientific animations
  • Industrial partnerships and support to start-up development
  • Scientific information release and science promotion to public

Main Contributions


The CyFlow facility has allowed IRIB teams to obtain the following scientific results:
  • Role of NAD in the functions, survival and phenotype of regulatory T cells
  • Phenotypic, quantitative and functional characterization of regulatory T cells after treatment with biodrugs in human clinical trials
  • Mechanism of immunological tolerance toward muscle-expressed antigens
  • Phenotypic and functional characterization of muscle stem cells
  • Phenotypic and functional characterization of cultured myoblast used in clinical trials
  • Phenotypic, functional characterization and cell sorting of olfactory ensheathing cells from the olfactory bulb
  • Phenotypic analysis and sorting of drosophila neurons
  • Immune monitoring of T cell responses in secondary lymphoid organs and tissues following immunization in experimental models
  • Analysis of B cell phenotype, number and function after treatment with biodrugs in pemphigus
  • Analysis of B cell phenotype, number and function during hypersensitivity reaction to drugs (DRESS syndrome)
