Synthetic dynamic hydrogels promote degradation-independent in vitro organogenesis

Matthias Lütolf, Nicolas Antoine Vincent Broguiere, Saba Rezakhani, Antonius Chrisnandy, Delphine Lorraine Perle Blondel

Epithelial organoids are most efficiently grown from mouse-tumour-derived, reconstituted extracellular matrix hydrogels, whose poorly defined composition, batch-to-batch variability and immunogenicity limit clinical applications. Efforts to replace such il ...

ISSCR standards for the use of human stem cells in basic research

Matthias Lütolf

The laboratory culture of human stem cells seeks to capture a cellular state as an in vitro surrogate of a biological system. For the results and outputs from this research to be accurate, meaning-ful, and durable, standards that ensure reproducibility and ...

Patterned gastrointestinal monolayers with bilateral access as observable models of parasite gut infection

Matthias Lütolf, Moritz Hofer

Organoids for modelling the physiology and pathology of gastrointestinal tissues are constrained by a poorly accessible lumen. Here we report the development and applicability of bilaterally accessible organoid-derived patterned epithelial monolayers that ...

The heparin binding domain of von Willebrand factor binds to growth factors and promotes angiogenesis in wound healing

Jeffrey Alan Hubbell, Matthias Lütolf, Yoji Tabata

During wound healing, the distribution, availability, and signaling of growth factors (GFs) are orchestrated by their binding to extracellular matrix components in the wound microenvironment. Extracellular matrix proteins have been shown to modulate angiog ...

3D Reconstitution of the Patterned Neural Tube from Embryonic Stem Cells

Matthias Lütolf, Adrian Ranga

Inducing organogenesis in 3D culture is an important aspect of stem cell research. Anterior neural structures have been produced from large embryonic stem cell (ESC) aggregates, but the steps involved in patterning such complex structures have been ill def ...

Perturbation of single hematopoietic stem cell fates in artificial niches

Matthias Lütolf

Hematopoietic stem cells (HSCs) are capable of extensive self-renewal in vivo and are successfully employed clinically to treat hematopoietic malignancies, yet are in limited supply as in culture this self-renewal capacity is lost. Using an approach at the ...

Capturing Cardiogenesis in Gastruloids

Matthias Lütolf, Romain Guiet, Nicolas Antoine Vincent Broguiere, Mehmet Ugur Girgin, Giuliana Rossi, Andrea Boni

Organoids are powerful models for studying tissue development, physiology, and disease. However, current culture systems disrupt the inductive tissue-tissue interactions needed for the complex morphogenetic processes of native organogenesis. Here, we show ...

Artificial three-dimensional niches deconstruct pancreas development in vitro

Matthias Lütolf, Anne Grapin-Botton, Adrian Ranga, Samy Gobaa, Chiara Greggio, Filippo De Franceschi

In the context of a cellular therapy for diabetes, methods for pancreatic progenitor expansion and subsequent differentiation into insulin-producing beta cells would be extremely valuable. Here we establish three-dimensional culture conditions in Matrigel ...

Development of bioactive hydrogel capsules for the 3D expansion of pluripotent stem cells in bioreactors

Matthias Lütolf, Yoji Tabata

Pluripotent stem cells hold great promise for many pharmaceutical and therapeutic applications. However, the lack of scalable methodologies to expand these cells to clinically relevant numbers is a major roadblock in realizing their full potential. To addr ...

Cell specific ingrowth hydrogels

Matthias Lütolf

Extracellular mimetic hydrogels formed from peptide crosslinkers and polyethylene glycol monomers permit cell-controlled invasion. The use of matrix metalloproteinase specific peptides might further allow for selective control of different cell-type invasi ...

Antiangiogenic immunotherapy suppresses desmoplastic and chemoresistant intestinal tumors in mice

Matthias Lütolf, Michele De Palma, Mauro Delorenzi, Mario Leonardo Squadrito, Sina Nassiri, Nikolche Gjorevski, Alan Nicolas Thierry Guichard

Mutations in APC promote colorectal cancer (CRC) progression through uncontrolled WNT signaling. Patients with desmoplastic CRC have a significantly worse prognosis and do not benefit from chemotherapy, but the mechanisms underlying the differential respon ...

Live mammalian cell arrays

Matthias Lütolf, Sebastian Maerkl, Samy Gobaa, Kristina Pan Woodruff, Luis Miguel Fidalgo Rabanera

High-content assays have the potential to drastically increase throughput in cell biology and drug discovery, but handling and culturing large libraries of cells such as primary tumor or cancer cell lines requires expensive, dedicated robotic equipment. We ...

Tissue geometry drives deterministic organoid patterning

Matthias Lütolf, Nathalie Brandenberg, Nikolche Gjorevski, Mikhail Nikolaev, Olga Mitrofanova

Epithelial organoids are stem cell-derived tissues that approximate aspects of real organs, and thus they have potential as powerful tools in basic and translational research. By definition, they self-organize, but the structures formed are often heterogen ...

Patient-derived mini-colons enable long-term modeling of tumor–microenvironment complexity

Matthias Lütolf, Nicolas Antoine Vincent Broguiere, Jakob Josef Langer, Lucie Carrié Tillard

Existing organoid models fall short of fully capturing the complexity of cancer because they lack sufficient multicellular diversity, tissue-level organization, biological durability and experimental flexibility. Thus, many multifactorial cancer processes, ...

Designing materials to direct stem-cell fate

Matthias Lütolf

Proper tissue function and regeneration rely on robust spatial and temporal control of biophysical and biochemical microenvironmental cues through mechanisms that remain poorly understood. Biomaterials are rapidly being developed to display and deliver ste ...

Metabolic control of adult neural stem cell activity by Fasn-dependent lipogenesis

Matthias Lütolf, Marlen Knobloch

Mechanisms controlling the proliferative activity of neural stem and progenitor cells (NSPCs) have a pivotal role to ensure life-long neurogenesis in the mammalian brain(1). How metabolic programs are coupled with NSPC activity remains unknown. Here we sho ...

Hydrogel microfluidics for the patterning of pluripotent stem cells

Matthias Lütolf, Steffen Cosson

Biomolecular signaling is of utmost importance in governing many biological processes such as the patterning of the developing embryo where biomolecules regulate key cell-fate decisions. In vivo, these factors are presented in a spatiotemporally tightly co ...
