In vitro Fate Mapping of Single Hematopoietic Stem Cells

The in vitro expansion of hematopoietic stem cells (HSC) for clinical applications is hampered by a rapid loss of HSC blood reconstitution capability in culture. While these rare cells can be stimulated to massively proliferate, cell divisions mostly resul ...

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

Matthias Lütolf, Mukul Girotra, Aline Roch, 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 ...

Dynamic interaction networks in a hierarchically organized tissue

Aline Roch

Intercellular (between cell) communication networks maintain homeostasis and coordinate regenerative and developmental cues in multicellular organisms. Despite the importance of intercellular networks in stem cell biology, their rules, structure and molecu ...

Brief Report: Single-Cell Analysis Reveals Cell Division-Independent Emergence of Megakaryocytes From Phenotypic Hematopoietic Stem Cells

Matthias Lütolf, Aline Roch, Vincent Trachsel

Despite increasingly stringent methods to isolate hematopoietic stem cells (HSCs), considerable heterogeneity remains in terms of their long-term self-renewal and differentiation potential. Recently, the existence of long-lived, self-renewing, myeloid-rest ...

Machine Learning of Hematopoietic Stem Cell Divisions from Paired Daughter Cell Expression Profiles Reveals Effects of Aging on Self-Renewal

Matthias Lütolf, Aline Roch

Changes in stem cell activity may underpin aging. However, these changes are not completely understood. Here, we combined single-cell profiling with machine learning and in vivo functional studies to explore how hematopoietic stem cell (HSC) divisions patt ...

Specification of haematopoietic stem cell fate via modulation of mitochondrial activity

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

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 ...

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

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 ...
