A satellite DNA array barcodes chromosome 7 and regulates totipotency via ZFP819

Didier Trono, Gabriela Ecco, Helen Mary Rowe

Mammalian genomes are a battleground for genetic conflict between repetitive elements and KRAB-zinc finger proteins (KZFPs). We asked whether KZFPs can regulate cell fate by using ZFP819, which targets a satellite DNA array, ZP3AR. ZP3AR coats megabase reg ...

TRIM37 prevents formation of centriolar protein assemblies by regulating Centrobin

Pierre Gönczy, Coralie Busso, Benita Wolf, Fernando Romero Balestra, Tessa Vivianne Averink, Alizée Buff

TRIM37 is an E3 ubiquitin ligase mutated in Mulibrey nanism, a disease with impaired organ growth and increased tumor formation. TRIM37 depletion from tissue culture cells results in supernumerary foci bearing the centriolar protein Centrin. Here, we chara ...

Phenotypic plasticity versus ecotypic differentiation under recurrent summer drought in two drought-tolerant pine species

Christoph Bachofen

Despite worldwide reports of high tree mortality, growing evidence indicates that many tree species are well adapted to survive repeated dry spells. The drought resilience of trees is related to their phenotypic plasticity and ecotypic differentiation. Whe ...

Silk Hydrogels as Soft Substrates for Neural Tissue Engineering

Jeffrey Alan Hubbell, Federico Tortelli, Amy Marie Hopkins

There is great need for soft biomaterials that match the stiffness of human tissues for tissue engineering and regeneration. Hydrogels are frequently employed for extracellular matrix functionalization and to provide appropriate mechanical cues. It is chal ...

Malachite Green Interferes with Postantibiotic Recovery of Mycobacteria

John McKinney, Neeraj Dhar, Ekaterina Gelman

The genus Mycobacterium comprises slow-growing species with generation times ranging from hours to weeks. The protracted incubation time before colonies appear on solid culture medium can result in overgrowth by faster-growing microorganisms. To prevent co ...

Spindle positioning in human cells relies on proper centriole formation and on the microcephaly proteins CPAP and STIL

Pierre Gönczy, Debora Keller, Petr Strnad, Fernando Romero Balestra, Gregor Kohlmaier

Patients with MCPH (autosomal recessive primary microcephaly) exhibit impaired brain development, presumably due to the compromised function of neuronal progenitors. Seven MCPH loci have been identified, including one that encodes centrosome protein 4.1 as ...

Hydrophilic Nanogels : Characterization and Behavior in Biological Environment

Catherine Ann Schütz

Hydrophilic nanocarriers, formed by electrostatic interaction between their oppositely charged components, are recognized as nanomaterials with an enormous potential as vectors in biomedical and pharmaceutical applications. However, comprehensive informati ...

3D collagen cultures under well-defined dynamic strain: A novel strain device with a porous elastomeric support

Melody Swartz, Alice Anna Tomei, Federica Boschetti

The field of mechanobiology has grown tremendously in the past few decades, and it is now well accepted that dynamic stresses and strains can impact cell and tissue organization, cell-cell and cell-matrix communication, matrix remodeling, cell proliferatio ...

Cell culture imaging using microimpedance tomography

Philippe Renaud, Olof Pontus Linderholm

We present a novel, inexpensive, and fast microimpedance tomography system for two-dimensional imaging of cell and tissue cultures. The system is based on four-electrode measurements using 16 planar microelectrodes (5 mum x 4 mm) integrated into a culture ...

Induction of A9 dopaminergic neurons from neural stem cells improves motor function in an animal model of Parkinsons disease

Romain Zufferey

Neural stem cells (NSCs) are widely endorsed as a cell source for replacement strategies in neurodegenerative disease. However, their usefulness is currently limited by the inability to induce specific neurotransmitter phenotypes in these cells. In order t ...
