Polarised three-dimensional cellular aggregates

Polarised three-dimensional cellular aggregates (or gastruloids) generated in vitro from one or more pluripotent stem cells are provided. Methods for obtaining polarised three-dimensional cellular aggregates and cells (e.g. progenitor cells and derivatives ...

Nicotinamide Pathway-Dependent Sirt1 Activation Restores Calcium Homeostasis to Achieve Neuroprotection in Spinocerebellar Ataxia Type 7

Johan Auwerx, Karim Laurent Gariani

Sirtuin 1 (Sirt1) is a NAD(+)-dependent deacetylase capable of countering age-related neurodegeneration, but the basis of Sirt1 neuroprotection remains elusive. Spinocerebellar ataxia type 7 (SCA7) is an inherited CAG-polyglutamine repeat disorder. Transcr ...

Targeting small molecule drugs to T cells with antibody-directed cell-penetrating gold nanoparticles

Francesco Stellacci, Ye Yang, Ahmet Bekdemir

We sought to develop a nanoparticle vehicle that could efficiently deliver small molecule drugs to target lymphocyte populations. The synthesized amphiphilic organic ligand-protected gold nanoparticles (amph-NPs) were capable of sequestering large payloads ...

Modeling hematopoietic stem cell dynamics in bioengineered niches

Sonja Giger

Bone marrow transplantation is a well-established medical procedure for the treatment of various hematologic diseases. However, the relatively low number of hematopoietic stem cells (HSCs) that can be harvested, especially from umbilical cord blood, limits ...

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 ...

Podosomes, But not the Maturation status, Determine the Protease-Dependent 3D Migration in human Dendritic cells

Romain Guiet

Dendritic cells (DC) are professional Antigen-Presenting Cells scattered throughout antigen-exposed tissues and draining lymph nodes, and survey the body for pathogens. Their ability to migrate through tissues, a 3D environment, is essential for an effecti ...

Rapid activation of tumor-associated macrophages boosts preexisting tumor immunity

Michele De Palma, Wei Xu

Depletion of immunosuppressive tumor-associated macrophages (TAMs) or reprogramming toward a proinflammatory activation state represent different strategies to therapeutically target this abundant myeloid population. In this study, we report that inhibitio ...

Novel tools to dissect stem cell metabolism at single cell level

Gennady Nikitin

Hematopoietic stem cells (HSC) are responsible for the life-long maintenance of our blood system. Their long-term capacity to both self-renew and differentiate and the ability to efficiently âhomeâ to their bone marrow niches when injected in the blood ...

In vitro fate mapping of stem cell development at the single cell level

Vincent Trachsel

Hematopoietic stem cells (HSCs) are responsible for the continuous production of all blood cells. This unique ability has made it possible to successfully use HSCs in the clinical setting to remedy various blood disorders. However, despite six decades of r ...

Autologous Cell Therapy Approach for Duchenne Muscular Dystrophy using PiggyBac Transposons and Mesoangioblasts

Nicolas Mermod

Duchenne muscular dystrophy (DMD) is a lethal muscle-wasting disease currently without cure. We investigated the use of the PiggyBac transposon for full-length dystrophin expression in murine mesoangioblast (MABs) progenitor cells. DMD murine MABs were tra ...
