The affinity precipitation for the isolation of biomolecules

Product isolation increasingly becomes a major bottleneck in molecular biotechnology. This is especially the case for the sensitive proteineous substances (recombinant proteins, antibodies) and lately also DNA, usually produced in low concentration. The cu ...

Tie2-expressing monocytes: regulation of tumor angiogenesis and therapeutic implications

Michele De Palma

Tumor-infiltrating myeloid cells are involved in crucial processes during tumor development. A subset of monocytes that express the angiopoietin receptor Tie2 play an important role in tumor angiogenesis. Selective depletion of these Tie2-expressing monocy ...

Digital holographic microscopy applied to life sciences

Christian Depeursinge, Tristan Colomb, Benjamin Rappaz, Pierre Marquet, Jonas Kühn, Florian Charrière

Digital holographic microscopy (DHM) is applied to life sciences applications and demonstrate its capability of real-time imaging and quantitative measurements of physiological parameters such as cell volume or mean cell hemoglobin concentration (MCHC) of ...

Tie2-expressing monocytes and tumor angiogenesis: regulation by hypoxia and angiopoietin-2

Michele De Palma

Recent findings indicate that tumor-associated macrophages are important drivers of tumor angiogenesis. Here, we review the essential role played by Tie2-expressing monocytes (TEM) in this phenomenon. TEMs are present in human blood and tumors and their el ...

Erythrocytes volume and refractive index measurement with a digital holographic microscope

Pierre Magistretti, Christian Depeursinge, Benjamin Rappaz, Pierre Marquet, Jonas Kühn, Florian Charrière

Digital holographic microscopy (DHM) is a technique that allows obtaining, from a single recorded hologram, quantitative phase image of living cell with interferometric accuracy. Specifically the optical phase shift induced by the specimen on the transmitt ...

Late endosomal cholesterol accumulation leads to impaired intra-endosomal trafficking

Françoise Gisou van der Goot Grunberg

BACKGROUND: Pathological accumulation of cholesterol in late endosomes is observed in lysosomal storage diseases such as Niemann-Pick type C. We here analyzed the effects of cholesterol accumulation in NPC cells, or as phenocopied by the drug U18666A, on l ...

Dynamics of lactate concentration and blood oxygen level-dependent effect in the human visual cortex during repeated identical stimuli

Rolf Gruetter

In vivo 1H NMR spectroscopy at 7 T was utilized to measure the changes in lactate concentration upon repeated identical visual stimuli, each lasting for 2 min. The average amplitude of these increases was found to be reduced over time (P < 0.01), from 0.13 ...

Method of enhancing proliferation and/or hematopoietic differentiation of stem cells

Olaia Maria Naveiras Torres-Quiroga

The present invention provides methods for inducing differentiation of a stem cell, such as an embryonic stem cell, into a hematopoietic stem cell, by expressing a cdx gene and/or a hox gene. The method is useful for generating expanded populations of hema ...

Analysis of potential transcriptomic biomarkers for Huntington's disease in peripheral blood

Mauro Delorenzi, Heike Runne

Highly quantitative biomarkers of neurodegenerative disease remain an important need in the urgent quest for disease-modifying therapies. For Huntington's disease (HD), a genetic test is available (trait marker), but necessary state markers are still in de ...

Biomolecular hydrogels formed and degraded via site-specific enzymatic reactions

Matthias Lütolf, Jeffrey Alan Hubbell, Martin Ehrbar

We present polymeric hydrogel biomaterials that are biomimetic both in their synthesis and degradation. The design of oligopeptide building blocks with dual enzymatic responsiveness allows us to create polymer networks that are formed and functionalized vi ...
