We have been using the U-CUP perfusion bioreactor for approximately 1 year. Due to excellent technical assistance, detailed protocols and a hands-on introduction at the facilities, only a short time was needed to get everything up and running in our lab.  We have carried out studies for up to 28 days with primary cells.  The system takes up little space, is easily handled and manipulated ensuring sterility and the results are highly reproducible between multiple samples. The team at CellecBiotek AG, especially Ms. Anna Gril and Dr. Adam Papadimitropoulos have provided professional guidance before and after the purchase, as well as well as excellent scientific support. It is not a matter of course that critical questions are discussed and that scientific details are openly shared – and for this we are very grateful!

We work on hematopoietic niches, more precisely on the interactions between hematopoietic stem cells and their microenvironment. We had previously developed an in vitro 3D niche composed of different bone marrow stromal cells and demonstrate the functionality of our model by its capacity to maintain or promote stemness/quiescence of hematopoietic stem cells. We wanted to increment our system by adding flow to better fit with the bone marrow physiology. We have purchased the U-CUP perfusion bioreactor from CELLEC. We really see that CELLEC proposes a “ready-to-use” system. 

However, despite the very user-friendly side of the U-CUP, we faced several difficulties to have a good flow and to correctly colonize our biomaterial. We wrote to the scientific expert to have advices and each time we had a quick and powerful answer adapted to our problems. They really perfectly know their product and have a large scientific culture to bring adapted solutions.

The U-CUP from Cellec fulfilled our wishes and, even more, open to us new research fields!

U-CUP flyer Poster

By adding the third dimension to cells environment one attempts to approach the milieu of the most biological tissues and organs found in nature, which are organised in 3D and to recapitulate the complex cellular interactions encountered therein. Therefore, 3D cell culture-based models are expected to capture similar aspects of those observed in vivo, leading thus to more relevant scientific results. In creating 3D cell culture models, U-CUP becomes an essential part of this process by both simplifying the procedure itself and generating solid scientific data.

How does it work?


Options for cell or tissue culture in the U-CUP bioreactor
  • Cell retrieval: Cells can be efficiently retrieved thanks to the perfusion flow by enzymatic digestion and then analyzed with typical lab equipment (e.g. RT-PCR, FACS)
  • Tissue harvesting: Tissue constructs are employed as such for in vitro analyses (e.g. histology) or pre-clinical use (e.g. in vivo implantation)
Porous scaffolds, providing a 3D template for cells to settle and grow or develop a tissue, are also available through our website
