Data Management, Processing and Analysis

Data Management, Processing and Analysis

In the life cycle of a biological data, which goes from its acquisition to the formatting of results, the processing and analysis constitute a key step to making sens of the data. Analysis uses a set of mathematical and statistical operations whose goal is to improve the quality of the data and to extract relevant information.

Whether the data is acquired on or off site, the data management and analysis platform offers a set of skills and makes available to users computing and software resources covering the fields of processing, analysis, instrumental development and mathematics/statistics. It is therefore possible to propose targeted offers ranging from the reconstruction of raw data to their exploitation. Depending on the user’s request, dedicated staff will evaluate the needs and propose an adapted service ranging from support to autonomy.

Cytometry

Cytometry

The platform allows the phenotyping of cells through the detection and identification of membrane and intracellular molecules. In order to purify a cell subpopulation, we also perform high throughput cell sorting, based on multi-parametric cell analysis. These subpopulations can then be studied for different parameters (transcriptome, proteome, in vivo transfer...).

RESTORE cytometry platform is a partner of the Toulouse Imaging Network Platform (TRI). It is certified ISO 9001 version 2015. The platform has a cell sorter, two analyzers and an image cytometer and offers a strong expertise on cells coming from solid tissues (adipose tissue, muscles, gums…). All the equipment is integrated in a L2 containment area.

The use of the equipment is open to research teams from public and private institutions, subject to acceptance of the projects by the manager.

Image Stream X

The specific applications of the Image Stream X are multiple, we can mention in particular :

  • morphology analysis,
  • internalization,
  • cell signaling and molecular translocation,
  • co-localization, cell interactions, cell cycle, apoptosis,
  • spot counting,
  • autophagy and cell death.

The platform has an imaging flow cytometer: Image Stream X Mark II (Merck-Luminex). This apparatus is equipped with 3 objectives (20x, 40x and 60x), 3 lasers (405nm, 488nm and 642nm) and a camera and can therefore read 6 parameters simultaneously.

The image files consisting of tens of thousands of cell images can be routinely analyzed using the IDEAS software: analysis of up to 500 morphometric and photometric parameters for each cell image using patented algorithms. The software is present on the platform and can be used under reservation conditions.

Acquisitions are carried out by the platform staff as a “service” at the request of the research teams and after acceptance by the platform manager. Analyses can be carried out with the help or under the supervision of the platform personnel, in the form of a service or collaboration.

Imaging

One of the challenges in biological imaging is to visualize biological structures and living organisms in three or four dimensions. CERT has a range of instruments and expertise to perform this type of analysis.

expertise

One of the challenges in biological imaging is to visualize biological structures and living organisms in three dimensions and in depth. CERT has the instruments and expertise to perform this type of analysis.

TA-segmentation2: 3-dimensional reconstructions of the whole inguinal adipose tissue of mice.

Lightsheet ZEISS Z7

The Z7 illuminates an entire plane of the sample with a sheet of light. These acquisitions are combined to produce a 3D image of the sample. Fluorescence emitted by the sample is detected at 90° to the illumination plane.

Advantages of this technology :

In-depth visualization of large samples (up to 1cm in diameter)
Reduced photobleaching and phototoxicity
Rapid acquisition: for live samples, 2 channels can be imaged simultaneously.

MacroSPIM (unavailable)

The MacroSPIM, a macroscope based on a light sheet excitation, makes it possible after optical clearing to visualize tissues and whole organs by rapid in depth 3D optical sectioning. This novel approach offers multi-view acquisition possibilities and opens up new perspectives in biological observation. This unique equipment, based on developments carried out in Barcelona (IRB), is now made available to the entire scientific community by CERT.

Confocal biphotonique

Finally, CERT is also equipped with a biphotonic confocal microscope.   The use of an infrared laser for the excitation using higher wavelengths than in conventional fluorescence microscopy allows to penetrate more deeply into living samples and thus allows 3D and deep acquisitions.

Example videos made with these instruments

Spectral imaging coupled with linear unmixing is the technique of choice for detecting and differentiating fluorophores in a biological sample, even in situations where spectral overlap exists. Autofluorescence can also be treated as a separate fluorophore to resolve from the signal of interest.

Confocal microscopy

CERT has a confocal bi-photonic AxioExaminer microscope (LSM 880 Zeiss) equipped with a pulsed Ti/Sa (Chohérent) laser (NLO) and 3 visible lasers. 

Using the QUASAR technology, this microscope offers the great advantage of simultaneous spectral detection in a single scan. It is possible, in a single acquisition, without loss of time and without space-time shift, to acquire and perfectly separate more than 4 fluorochromes whose spectra overlap.

  • This technology also makes it possible to eliminate autofluorescence signal generated by tissues.
  • The NLO system also gives access to the second harmonic generation (SHG) signal, thus allowing to reveal the organization of collagen fibers of the extracellular matrix or the striations of skeletal muscles without labelling.
  • This equipment also allows to perform 3D and 4D imaging in vivo in small animals.

This technology makes it possible to follow living organisms over time with cellular resolution.

Videomicroscopes, Biphotons, SPIM

Real-time microscopy consists of imaging living samples over time with cellular resolution while maintaining temperature and respiratory conditions compatible with the survival of the samples. Samples can be cell cultures or whole organisms (mice, fish, drosophila), including tissue explants and spheroids.

We propose a variety of equipment : videomicroscopes, Biphotons, SPIM, that are all capable of Real-Time imaging. These equipments are coupled with specific modules that control the survival parameters of the samples (thermostatic chambers, CO2, anesthesia, respiratory and small animal monitoring systems).

Physioxia & Hypoxia

Physioxia
& Hypoxia

Within tissues, the oxygen level is much lower than that of the atmosphere in which cells are conventionally grown (21% O2). In order to study cell metabolism in conditions close to those present in tissues, it is essential to grow them in an oxygen-controlled atmosphere. Cell oxygenation, at the heart of Inserm and Restore's research, has been awarded a prize in 2019.

expertise

This incubator mimics the physiological oxygenation conditions of cells or tissues throughout their culture, without fluctuation of the atmospheric environment. It allows the study of different populations of stem cells in conditions close to those encountered in vivo and to lead to new therapeutic leads. (complete article).

The X-Vivo apparatus (Biospherix) is an enclosure with a fully controlled oxygen atmosphere. It allows, thanks to its different modules, to realize simultaneously different cultures with different levels of oxygen (1%, 2%, 5%, …) according to the experimental demands and this throughout the culture:

  • 6 independent incubators with specific oxygen control

  • 2 independent working modules with specific oxygen control

  • 2 independent transfer airlocks

  • 1 module with a microscope

Fluxomics

Fluxomics

In the recent years, the study of metabolism has been at the heart of physiology and health challenges. The applications are numerous and include the comprehensive understanding of normal and pathological physiology, the identification of new therapeutic targets and personalize medicine and therapeutic follow-up. The ability to thoroughly investigate metabolism is therefore a major challenge in the comprehensive understanding of aging and in the fight against diseases such as cancer.

eMotion is a facility (scientific head: Prof. JC Portais) that provide to the scientific community with the tools and expertise to measure metabolic fluxes, including both carbon (matter) and electrons (energy) fluxes, at the biological scales ranging from 2D/3D cultured cells to whole organisms. eMotion encompasses one experimental plateau and two analytical plateaus:

  • The experimental plateau (Head Dr Yannick Jeanson) integrates all the experimental stages ranging from the experimental design to its implementation until the samples collection. It also contains appropriate labs to perform in vitro or in vivo isotopic tracing experiments.
  • The FluxoVivo plateau (Head Dr Spiro Khoury) which is dedicated to measuring carbon fluxes using isotopic tracing approaches.
  • The RedoxHome plateau (Head Dr Yannick Jeanson) which contains different analytical devices allowing to assess electron fluxes (respiration, redox states of coenzymes, redox potential).

The name eMotion contains the idea of dynamics, and the overall objective of the facility is to provide support to measure the actual dynamics of metabolism.

La mitochondrie est le site majeur de la production d’ATP au sein de la cellule et joue un rôle primordial dans le métabolisme redox cellulaire. L’activité mitochondriale peut être modifiée lors de la mise en place de pathologies telles que les maladies métaboliques, le cancer ou encore lors du vieillissement. Cette activité mitochondriale peut être évaluée grâce à la mesure de la consommation en oxygène à l’aide d’un oxygraphe.

Oxygraphes

Les oxygraphes de type Oroboros présents sur le CERT sont des instruments très sensibles grâce à leurs cuves hermétiques et leurs sondes de Clark. Ils permettent d’étudier l’activité mitochondriale sur tissus (homogénats, perméabilisés), cellules et mitochondries isolées grâce à l’utilisation de différents substrats et drogues. Les oxygraphes de type Oroboros ne sont pas limités en nombre d’injection par expérience ce qui permet une étude plus précise de l’activité mitochondriale :
