Dissecting the role of biliary epithelial cells during non-alcoholic fatty liver disease progression

Ece Yildiz

The liver is the largest solid organ and the only one capable of using regenerative mechanisms to recover its mass fully. Although liver regeneration from acute injuries has been effective and extensively studied, chronic liver damage has adverse effects o ...

Targeted search for scaling genes reveals matrix metalloproteinase 3 as a scaler of the dorsal-ventral pattern in Xenopus laevis embryos

Daria Korotkova

How embryos scale patterning according to size is still not fully understood. Through in silico screening and analysis of reaction-diffusion systems that could be responsible for scaling, we predicted the existence of genes whose expression is sensitive to ...

Towards an artificial cell: Development of a system which self-regenerates the protein components of the PURE system in microfluidic reactors

Barbora Lavickova

Thanks to recent advancements in synthetic biology, the dream of creating a synthetic cell has become feasible. However, due to its inherent complexity, one of the fundamental functions of all living systems, i.e., self-replication, remains to be introduce ...

Appendage regeneration is context dependent at the cellular level

Can Aztekin

Species that can regrow their lost appendages have been studied with the ultimate aim of developing methods to enable human limb regeneration. These examinations highlight that appendage regeneration progresses through shared tissue stages and gene activit ...

All-Polymer Printed Low-Cost Regenerative Nerve Cuff Electrodes

Silvestro Micera

Neural regeneration after lesions is still limited by several factors and new technologies are developed to address this issue. Here, we present and test in animal models a new regenerative nerve cuff electrode (RnCE). It is based on a novel low-cost fabri ...

A partially self-regenerating synthetic cell

Sebastian Maerkl, Barbora Lavickova, Nadanai Laohakunakorn

Self-regeneration is a fundamental function of all living systems. Here we demonstrate partial molecular self-regeneration in a synthetic cell. By implementing a minimal transcription-translation system within microfluidic reactors, the system is able to r ...

Smart Hydrogels for the Augmentation of Bone Regeneration by Endogenous Mesenchymal Progenitor Cell Recruitment

Matthias Lütolf, Olaia Maria Naveiras Torres-Quiroga, Aline Roch, Philipp Sebastian Lienemann, Stéphanie Elisabeth Metzger, Queralt Vallmajó Martín, Martin Ehrbar, Vincent Milleret, Manuel Koch, Panagiota Papageorgiou

The treatment of bone defects with recombinant bone morphogenetic protein-2 (BMP-2) requires high doses precluding broad clinical application. Here, a bioengineering approach is presented that strongly improves low-dose BMP-2-based bone regeneration by mob ...

The Transcription Factor Nfix Requires RhoA-ROCK1 Dependent Phagocytosis to Mediate Macrophage Skewing during Skeletal Muscle Regeneration

Giuliana Rossi

Macrophages (MPs) are immune cells which are crucial for tissue repair. In skeletal muscle regeneration, pro-inflammatory cells first infiltrate to promote myogenic cell proliferation, then they switch into an anti-inflammatory phenotype to sustain myogeni ...

Active biomaterials for mechanobiology

Mahmut Selman Sakar, Berna Ayse Özkale Edelmann

Active biomaterials offer novel approaches to study mechanotransduction in mammalian cells. These material systems probe cellular responses by dynamically modulating their resistance to endogenous forces or applying exogenous forces on cells in a temporall ...

Bile Acids Signal via TGR5 to Activate Intestinal Stem Cells and Epithelial Regeneration

Kristina Schoonjans, Alessia Perino, Maroun Bou Sleiman, Giovanni Sorrentino, Ece Yildiz, Gaby El Alam

BACKGROUND & AIMS: Renewal and patterning of the intestinal epithelium is coordinated by intestinal stem cells (ISCs); dietary and metabolic factors provide signals to the niche that control ISC activity. Bile acids (BAs), metabolites in the gut, signal nu ...
