Ultra-rapid prototyping of flexible, multi-layered microfluidic devices via razor writing

Matthias Lütolf, Nathalie Brandenberg, Steffen Cosson

The fabrication of microfluidic devices is often still a time-consuming and costly process. Here we introduce a very simple and cheap microfabrication process based on "razor writing", also termed xurography, for the ultra-rapid prototyping of microfluidic ...

Drug discovery through stem cell-based organoid models

Matthias Lütolf, Adrian Ranga, Nikolche Gjorevski

The development of new drugs is currently a long and costly process in large part due to the failure of promising drug candidates identified in initial in vitro screens to perform as intended in vivo. New approaches to drug screening are being developed wh ...

Next-generation cancer organoids

Matthias Lütolf, Nicolas Antoine Vincent Broguiere

Organotypic models of patient-specific tumours are revolutionizing our understanding of cancer heterogeneity and its implications for personalized medicine. These advancements are, in part, attributed to the ability of organoid models to stably preserve ge ...

3D extrusion bioprinting

Matthias Lütolf, Tania Hübscher

Three-dimensional (3D) bioprinting strategies use computer-aided processes to enable automated simultaneous spatial patterning of cells and/or biomaterials. These technologies are suitable for a broad range of biomedical applications owing to their capabil ...

Microscale patterning of hydrogel stiffness through light-triggered uncaging of thiols

Matthias Lütolf, Katarzyna Mosiewicz, Laura Kolb

Mammalian cell behavior is strongly influenced by physical and chemical cues originating from the extracellular matrix (ECM). In vivo, ECM signals are displayed in a spatiotemporally complex fashion, often composed as gradients and in concentration profile ...

Enhancing the Reliability and Throughput of Neurosphere Culture on Hydrogel Microwell Arrays

Matthias Lütolf, Stefan Kobel

The neurosphere assay is the standard retrospective assay to test the self-renewal capability and multipotency of neural stem cells (NSC) in vitro. However, it has recently become clear that not all neurospheres are derived from a NSC and that on conventio ...

Biomaterials meet microfluidics: building the next generation of artificial niches

Matthias Lütolf, Stefan Kobel

Biomaterials are increasingly being developed as in vitro microenvironments mimicking in vivo stem cell niches. However, current macroscale methodologies to produce these niche models fail to recapitulate the spatial and temporal characteristics of the com ...

Engineering Stem Cell Self-organization to Build Better Organoids

Matthias Lütolf

Organoids form through self-organization processes in which initially homogeneous populations of stem cells spontaneously break symmetry and undergo in-vivo-like pattern formation and morphogenesis, though the processes controlling this are poorly characte ...

NAD+ repletion improves mitochondrial and stem cell function and enhances life span in mice

Johan Auwerx, Matthias Lütolf, Kristina Schoonjans, Dongryeol Ryu, Hongbo Zhang, Davide D'Amico, Keir Joe Menzies, Xu Wang, Karim Laurent Gariani, Peiling Luan

Adult stem cells (SCs) are essential for tissue maintenance and regeneration yet are susceptible to senescence during aging. We demonstrate the importance of the amount of the oxidized form of cellular nicotinamide adenine dinucleotide (NAD(+)) and its imp ...

Stem cell niche engineering through droplet microfluidics

Matthias Lütolf, Simone Allazetta

Stem cells reside in complex niches in which their behaviour is tightly regulated by various biochemical and biophysical signals. In order to unveil some of the crucial stem cell-niche interactions and expedite the implementation of stem cells in clinical ...

Multimodal characterization of murine gastruloid development

Matthias Lütolf, Alexandre Gauthier Aurèle Mayran, Stefano Davide Vianello, Raphaël Ortiz

Gastruloids are 3D structures generated from pluripotent stem cells recapitulating fundamental principles of embryonic pattern formation. Using single-cell genomic analysis, we provide a resource mapping cell states and types during gastruloid development ...

Next-generation patient models for colorectal cancer research

Matthias Lütolf, Luis Francisco Lorenzo Martin

Lab-grown 'mini-colons' enable the simulation of colorectal tumor dynamics and the high-resolution study of interactions with cells from the tumor's native microenvironment. These next-generation organoids offer a wealth of new experimental opportunities, ...

Heparin-binding domain of fibrin(ogen) binds growth factors and promotes tissue repair when incorporated within a synthetic matrix

Jeffrey Alan Hubbell, Matthias Lütolf, Adrian Ranga, Priscilla Suhasna Maithili Briquez

By binding growth factors (GFs), the ECM tightly regulates their activity. We recently reported that the heparin-binding domain II of fibronectin acts as a promiscuous high-affinity GF-binding domain. Here we hypothesized that fibrin, the provisional ECM d ...
