In Vivo Pre-Instructed HSCs Robustly Execute Asymmetric Cell Divisions In Vitro

Matthias Lütolf, Aline Roch, Mukul Girotra, Vincent Trachsel

Hematopoietic stem cells (HSCs) are responsible for life-long production of all mature blood cells. Under homeostasis, HSCs in their native bone marrow niches are believed to undergo asymmetric cell divisions (ACDs), with one daughter cell maintaining HSC ...

Measurement of Mitochondrial Mass and Membrane Potential in Hematopoietic Stem Cells and T-cells by Flow Cytometry

Olaia Maria Naveiras Torres-Quiroga, George Coukos, Mukul Girotra, Nicola Vannini, Alexandre Harari

A fine balance of quiescence, self-renewal, and differentiation is key to preserve the hematopoietic stem cell (HSC) pool and maintain lifelong production of all mature blood cells. In recent years cellular metabolism has emerged as a crucial regulator of ...

The NAD-Booster Nicotinamide Riboside Potently Stimulates Hematopoiesis through Increased Mitochondrial Clearance

Johan Auwerx, Matthias Lütolf, Bart Deplancke, Carlos Canto Alvarez, Olaia Maria Naveiras Torres-Quiroga, George Coukos, Aurélien Laurent Jean-Charles Oggier, Loïc Tauzin, Dongryeol Ryu, Eija Riitta Pirinen, Pedro Romero, Vasco Ledebur de Antas de Campos, Mukul Girotra, Joanna Ratajczak, Josefine Catharina Pedersen Tratwal, Nicola Vannini, Pernille Yde Rainer, Gennady Nikitin, Federico Sizzano, Simone Ragusa, Vincent Trachsel, Sonja Giger, Shanti Rojas-Sutterlin, Yannick Lionel Yersin, Martin Ehrbar

It has been recently shown that increased oxidative phosphorylation, as reflected by increased mitochondrial activity, together with impairment of the mitochondrial stress response, can severely compromise hematopoietic stem cell (HSC) regeneration. Here w ...

Specification of haematopoietic stem cell fate via modulation of mitochondrial activity

Johan Auwerx, Matthias Lütolf, Olaia Maria Naveiras Torres-Quiroga, Aline Roch, Vasco Ledebur de Antas de Campos, Mukul Girotra, Nicola Vannini, Gennady Nikitin, Sonja Giger

Haematopoietic stem cells (HSCs) differ from their committed progeny by relying primarily on anaerobic glycolysis rather than mitochondrial oxidative phosphorylation for energy production. However, whether this change in the metabolic program is the cause ...

Methods & compounds useful in hematopoietic stem cell medicine

Johan Auwerx, Matthias Lütolf, Olaia Maria Naveiras Torres-Quiroga, Mukul Girotra, Nicola Vannini

The present invention relates to a specific marker for stem cells having long-term multi-lineage blood reconstitution capability and uses thereof for the preparation of cell composition in view of hematopoietic stem cell medicine and in particular regenera ...

Deciphering Metabolic Regulation of Hematopoietic Stem Cell Fate

Mukul Girotra

Hematopoietic stem cells (HSCs) are responsible for life-long production of all mature blood cells. This unique characteristic makes them an ideal candidate for cell-based therapies to treat various hematological malignancies. Their extensive use in the cl ...

Automated analysis of single stem cells in microfluidic traps

Matthias Lütolf, Alessandra Griffa, Olivier Burri, Arne Seitz, Stefan Kobel, Mukul Girotra

We report a reliable strategy to perform automated image cytometry of single (non-adherent) stem cells captured in microfluidic traps. The method rapidly segments images of an entire microfluidic chip based on the detection of horizontal edges of microflui ...

Graph Chatbot

Chattez avec Graph Search

Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.

AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
