Since stem cells have the unique ability to produce more of themselves (i.e. to "self-renew") and to generate specialized tissue cells, they are an ideal source of cells for regenerative medicine and in vitro tissue models. In order to fully exploit this p ...

The aim of this study was to gain a better understanding of orbitally shaken bioreactors (OSRs) operated without controllers for pH and dissolved oxygen (DO) concentration. We used cylindrical OSRs with working volumes ranging from 250mL to 200L to determi ...

OrbShake Bioreactors for Mammalian Cell Cultures

Stéphanie Tissot

Most of the biopharmaceuticals nowadays are produced by animal cells. The worldwide demand for a specific group of biopharmaceuticals, the monoclonal antibodies (mAbs), has significantly increased this last decade. The mAbs are used as therapeutics in part ...

Carbon Nanotubes-Based Electrochemical Sensing for Cell Culture Monitoring

Giovanni De Micheli, Sandro Carrara, Cristina Boero, Giovanna Del Vecchio

Monitoring of metabolic compounds, such as glucose and lactate, is extensively reported in literature, especially for clinical purposes. Instead, the application of such technologies for monitoring metabolites in cell cultures has not been explored. From o ...

The growing demand of biopharmaceutical products is boosting the market for therapeutic recombinant proteins (r-proteins). More than half of the 140 r-proteins that have gained approval for human therapeutic use are manufactured in mammalian cells that mak ...

Determination of a scale-up factor from mixing time studies in orbitally shaken bioreactors

Christos Comninellis, Florian Maria Wurm, Mohamed Farhat, David Hacker, Stéphanie Tissot

Efficient mixing in bioreactors is essential in order to avoid concentration gradients which can be harmful for mammalian cells. To study mixing and its scalability in orbitally shaken cylindrical bioreactors, we measured mixing times in containers with no ...

Use of Orbital Shaken Disposable Bioreactors for Mammalian Cell Cultures from the Milliliter-Scale to the 1,000-Liter Scale

Alfio Quarteroni, Florian Maria Wurm, David Hacker, Mathieu Benjamin Stettler, Xi Zhang

Driven by the commercial success of recombinant biopharmaceuticals, there is an increasing demand for novel mammalian cell culture bioreactor systems for the rapid production of biologicals that require mammalian protein processing. Recently, orbitally sha ...

Microfluidics-generated immobilized biomolecule gradients on hydrogels

Matthias Lütolf, Stefan Kobel, Steffen Cosson

Extra-cellular matrix (ECM) tethered morphogen gradients play an important role in tissue development and regeneration. There is currently only a limited set of model systems which can mimic these gradients in an artificial ECM-like environment. We have de ...

Most tissue engineering approaches include the delivery of reparative cells to a damaged host tissue. Generally these cells are sought to be of a stem cell character since they retain a high potential for proliferation and differentiation into diverse phen ...
