Cell and Tissue Culture

  • Services
  • Members
  • Publications

Although cell culture and isolation of cells from tissues seems trivial at first, every cell culture is different. Depending on their origin, cells grow at a different rate, have different nutritional requirements, and have different periods of sustainability. Our cell lines include adherent cells and cells that can be maintained in suspension. Tumor cell lines are available to customers after they have been characterized (with knowledge of their mutations). Our cell lines include genetically modified cell lines that can be used in well-defined experiments. Our cell lines are of human or animal origin, we currently do not conduct experiments with plant cells.


Cell and tissue culturing

The Cell and Tissue Culture Core Facility provides the opportunity to design, prepare (thaw, passage and handle specific cell lines), perform experiments and evaluate results based on personalized cell and tissue cultures using its comprehensive instruments and equipments. In addition to the experimental set-up based on two-dimensional cell and tissue cultures, users have the option to set up an experimental model based on complex cell and tissue cultures. Users are also provided with the ability to dissociate primary cells from animal or human tissues or to separate a particular cell population from body fluids.

The available cell cultures are cultured in all cases at 37 °C incubators with 5% CO2 and high humidity. The experiments are performed in a laminar flow cabinet under sterile conditions. In addition to the instruments highlighted below, we have the essential instruments and tools needed for cell and tissue culture techniques, such as:

  • Microscope for monitoring cell cultures
  • Incubators
  • Cell culture hoods (even for cytostatic treatment)
  • Nitrogen tank suitable for long-term storage of our cell lines
  • Different types of cell culture media and supplements

Isolation and characterization of extracellular vesicles

Extracellular vesicles (EVs) are membrane-delimited particles released from all type of cells into the extracellular space. According to their size and biogenesis EVs can be differentiated into three subgroups such as exosomes, microvesicles and apoptotic bodies. These vesicles can be isolated from many body fluids (blood, urine, breast milk etc.) or from cell culture supernatant. Apoptotic bodies and microvesicles can be elutriated using high-speed centrifugation, but exosomes require PEG-based isolation method.

We are able to isolate exosomes from the following fluids:

  • blood serum
  • blood plasma
  • urine
  • cell culture supernatant
  • other body fluid (e.g. milk)

In our laboratory, it is possible to characterize the isolated vesicles (based on size and quantity), which is performed with the Malvern NanoSight NS300 device using nanoparticle tracking analysis (NTA).


ESCO biological safety cabinet (C214)

Esco biological safety cabinet provides appropriate environment for basic cell culture procedures, expreimental set-ups and ensures the required sterile condition.

EuroClone Safemate CYTO Cytotoxic Drug Handling Cabinet (C214)

The EuroClone s@femate 1.2 cyto safety cabinet allows safe handling of cytostatics in the Cell and Tissue Culture Core Facility, keeping both the operator and the sample as well as the environment protected thanks to the built-in 3 H14 HEPA filters. To use the cabinet, wearing protective clothing and following the rules for working with cytostatics is obligatory!

NanoSight NS300

The Malvern Panalytical NanoSight NS300 Instrument provides an easy-to-use, reproducible platform for nanoparticle characterization, especially size characterization of extracellular vesicles. Particles in liquid suspension are loaded into a sample chamber. In the path of the beam the particles scatter the laser light which is easily collected by the microscope objective and is viewed with a digital camera. The camera captures a video of the particles moving under Brownian motion. The NS300 allows rapid analysis of the size distribution and concentration of all types of nanoparticles from 10 nm - 2 µm in diameter, depending on the instrument configuration and sample type. With the ability to be supplied with interchangeable laser modules and the introduction of a motorized filter wheel means different fluorescent labels can be analyzed.

Detectable particle size: 10nm - 2000nm

Lasers: 488nm (Blue), 532nm (Green)

Concentration: 109 particle / ml

NS300 can be applied in the development of different delivery system studies:

  • Viral vaccine research
  • Nano-toxicology and viral vaccine detection
  • Protein aggregation studies
  • Extracellular vesicle characterization in different stages of diseases
  • Exosome and microvesicle characterization

nCounter SPRINT Profiler

The nCounter SPRINT Profiler is a platform that allows you to measure nearly 800 targets simultaneously in 12 samples in just 7 hours. It is also able to analyze samples from relatively low concentrations: 1 - 50 ng for RNA, 5 - 300 ng for DNA, 250 ng - 2.5 μg for protein, which requires only a short sample preparation process.

The analysis of raw data can be done easily with the help of nSolver ™ Analysis Software.

More information about the instrument is available here.

Available panels and assays:

QuantStudio™ 12K Flex Real-Time PCR System

The QuantStudio™ 12K Flex Real-Time PCR system takes qPCR technology to a next level with maximum throughput and minimal resources.
