A new approach to design artificial 3D micro-niches with combined chemical, topographical and rheological cues
The in vitro methods to recapitulate environmental cues around cells are usually optimized to test a specific property of the environment (biochemical nature or the stiffness of the extra cellular matrix (ECM), or nanotopography) for its capability to induce defined cell behaviors (lineage commitment, migration). Approaches that combine different environmental cues in 3D to assess the biological response of cells to the spatial organization of different biophysical and biochemical cues are growingly being developed. … Read the scientific paper

In situ photopatterning of pressure-resistant hydrogel membranes with controlled permeabilities in PEGDA microfluidic channels.
We report the fabrication of highly permeable membranes in poly(ethylene glycol) diacrylate (PEGDA) channels, for investigating ultra- or micro-filtration, at the microfluidic scale. More precisely, we used a maskless UV projection setup to photopattern PEG-based hydrogel membranes on a large scale (mm–cm), and with a spatial resolution of a few microns. Read the scientific paper

Altered microtubule dynamics and vesicular transport in mouse and human MeCP2- deficient astrocytes.
Rett syndrome (RTT) is a rare X-linked neurodevelopmental disorder, characterized by normal post-natal development followed by a sudden deceleration in brain growth with progressive loss of acquired motor and language skills, stereotypic hand movements and severe cognitive impairment.

Multiprotein Printing by Light-Induced Molecular Adsorption.
Light-induced molecular adsorption of proteins (LIMAP) allows for quantitative sub-micrometer-resolution printing of multiple biomolecules. Surface-bound gradients are patterned within minutes over an entire glass cover-slip. LIMAP is used to perform selective immuno-assays, to dynamically control the adhesion of individual cells, and to achieve hierarchical co-cultures instrumental for tissue engineering.
