Your project of experiment with PRIMO

“The team is studying the recruitment mechanisms of white blood during an immune response. The complex orchestration of white blood cells traffic between blood/lymph systems, lymph nodes and inflammation zones relies on sophisticated but still poorly understood signaling routes that guide cells toward precise targets.
Our aim is to develop in vitro experimentation to decipher guiding mechanisms involved in vivo.”

PRIMO technology is particularly adapted to design in vitro microdevices patterned with controlled patches of the signaling proteins relevant for white blood cell migration.

Primary human T lymphocytes on specific adhesion strips.


“We previously used PDMS microstamping but the amount of deposited proteins was uncontrolled and we had difficulties to print gradients.
We chose to use PRIMO because it allows to print gradients as well as a combination of several proteins”

Little extra which makes all the difference

Performances :

The optical printing system of PRIMO is highly performant and user-friendly. The best is still to come.

“We are working on the generation of 3D cellular microenvironments to reproduce Hematopoietic Niches. PRIMO will be used to generate 3D photo-polymerized microenvironments and to pattern them to localize different cell populations involved in the hematopoiesis.”

“My research focuses on the mechanical aspects of cell division. With the PRIMO system we wanted to control cellular geometry to impose spatial constraints during mitotic progression.”

“We are interested in imaging subcellular localization of certain cell-surface receptors and check whether they colocalize with focal-adhesion complexes. For this purpose, we are interested in making different types of patterns of Fibronectin with subcellular dimensions.”

“My research project aims at unravelling how a T cell switches from a fast migratory state to a stationary state upon activation. To do so, I perform live cell imaging of T cells migrating inside micro-fabricated channels coated with activating molecules. However, with this approach, I do not control when and where a T cell encounters the activating molecules.”

“Protein micropatterning represents an excellent tool to probe the behavior and functions of cellular systems. PRIMO is specially suited for our experiments, in which the cell-substrate interaction needs to be precisely adjusted both throughout the substrates and in time, in order to control the dynamic behaviour of cell monolayers.”
