Engineered signaling centers for the spatially controlled patterning of human pluripotent stem cells

Matthias Lütolf, Felix Naef, Yoji Tabata, Eric Paquet, François Réal Rivest, Ambroise Roger Vuaridel, Andrea Manfrin

Signaling centers, localized groups of cells that secrete morphogens, play a key role in early development and organogenesis by orchestrating spatial cell fate patterning. Here we present a microfluidic approach that exposes human pluripotent stem cell (hP ...

Progress and potential in organoid research

Matthias Lütolf, Giuliana Rossi, Andrea Manfrin

Tissue and organ biology are very challenging to study in mammals, and progress can be hindered, particularly in humans, by sample accessibility and ethical concerns. However, advances in stem cell culture have made it possible to derive in vitro 3D tissue ...

3D Inkjet Printing of Complex, Cell-Laden Hydrogel Structures

Matthias Lütolf, Andrea Negro, Thibaud Cherbuin

Inkjet printing is widely considered a promising strategy to pattern hydrogels and living cells into three-dimensional (3D) constructs that structurally resemble tissues in our body. However, this approach is currently constrained by the limited control ov ...

Pharmacological induction of a progenitor state for the efficient expansion of primary human hepatocytes

Didier Trono, Matthias Lütolf, Evaristo Jose Planet Letschert, Marc Samuel Friedli, Nathalie Brandenberg, Marco Cassano, Carmen Maria Unzu Ezquerro

The liver is an organ with strong regenerative capacity, yet primary hepatocytes have a low amplification potential in vitro, a major limitation for the cell-based therapy of liver disorders and for ex vivo biological screens. Induced pluripotent stem cell ...

Organs-on-chip monitoring: sensors and other strategies

Philippe Renaud, Tugba Kilic, Sandro Carrara, Francesca Stradolini, Fatemeh Navaee

As a paradigm shifting player of tissue engineering, organs-on-chips (OOCs) are considered to hold great potential for future “clinical trials on chip” as well as a step forward to design personalized medicine. Despite all ethical concerns raised by commun ...

Two-Dimensional Label-Free Affinity Analysis of Tumor-Specific CD8 T Cells with a Biomimetic Plasmonic Sensor

Hatice Altug, Xiaokang Li, George Coukos, Maria Soler Aznar, Aurélian Michel John-Herpin

The screening and analysis of T cells functional avidity for specific tumor-associated antigens is crucial for the development of personalized immunotherapies against cancer. The affinity and kinetics of a T cell receptor (TCR) binding to the peptide-major ...
