Technologies

Cell isolation form different donor tissue (e.g. umbilical cord, adipose tissue, bone marrow)

Advanced 3 D techniques for stem cell isolation

Cultivation of cell under hypoxic conditions

Application of dynamic (3 D) culture conditions incl. mechanical stimulation (e.g. shear stress, straining/loading)

Characterization and functional testing of stem cells

Biomaterial testing

Co- culture systems

Integration of sensors in tailor made cultivation systems for monitoring cell culture processes (e.g. oxygen, pH, glucose)

Bioreactor Systems

  • A small catheter inside of the reaction chamber delivers real time data of the graft cultured.
  • Stirred tanks are widely used in fermentation, but can also be used for dynamic culture of (stem) cells.
  • These small reactor chambers are connected to peristaltic pumps and enable continuous or dynamic perfusion of small TE-grafts
  • Porous scaffolds seeded with cells can be perfused in parallel
  • As the name implies this reactor consists of tightly packed hollow fibres. The space inside and outside of the fibres can be seeded with cells and perfused indipendently.
  • The individual fibres in more detail.
  • Similar as a sirred tank, but the mixing of the cells is done by a vertical wheel ("Hamsterrad") that can be driven by magnetic force.
  • Another perfusable reactor; the chamber is devided by a permeable membrane where the cells can grow on both the top and bottom side.
  • The experimental set up including media reservoir and pump inside a cell culture incubation system

Laboratory Equipment

  • Equipped with 3 pumps, 3 motors and a dark field microscope
  • With the use of nitrogen it is possible to provide a "hypoxic" (5% O2) environment within our incubators for the cells
  • One of 4 sterile work benches for aseptic cell culture
  • The ZRP system allows for dynamic cell culture in a closed and independent system with different reactor chambers available.
