The use of PRIMO in this context proved absolutely essential since it allowed us to create artificial microniches in 3D where we could control up to 150 combinations of environ-mental cues.
My research work consists in understanding how microenvironmental cues influence, guide and shape cell-cell contacts. We are currently particularly interested in determining the role of the biophysical environment in the establishment of apico-basal polarity in mammary gland cells and in liver cells.
We are proud to collaborate with Leica Microsystems to ensure you obtain the best cell samples for cryo-ET! PRIMO micropatterning + Leica cryo-CLEM = Advanced workflow for whole cell cryo-ET
