Engineered signaling centers for the spatially controlled patterning of human pluripotent stem cells

Matthias Lütolf, Felix Naef, Yoji Tabata, Eric Paquet, François Réal Rivest, Ambroise Roger Vuaridel, Andrea Manfrin

Signaling centers, localized groups of cells that secrete morphogens, play a key role in early development and organogenesis by orchestrating spatial cell fate patterning. Here we present a microfluidic approach that exposes human pluripotent stem cell (hP ...

Understanding semiconductor nanostructures via advanced electron microscopy and spectroscopy

Reza Zamani

Transmission electron microscopy (TEM) offers an ample range of complementary techniques which are able to provide essential information about the physical, chemical and structural properties of materials at the atomic scale, and hence makes a vast impact ...

Efficient transdifferentiation of human dermal fibroblasts into skeletal muscle

Noaf Salah Ali Alwahab

Skeletal muscle holds significant regenerative potential but is incapable of restoring tissue loss caused by severe injury, congenital defects or tumour ablation. Consequently, skeletal muscle models are being developed to study human pathophysiology and r ...

One plus one greater than two: high-performance inverted planar perovskite solar cells based on a composite CuI/CuSCN hole-transporting layer

Ulf Anders Hagfeldt, Zerrin Yumak

The low-cost and stable inorganic p-type semiconductor copper(i) iodide (CuI) is a promising hole-transporting layer (HTL) material for inverted planar perovskite solar cells (PSCs). However, the power conversion efficiencies (PCEs) of inverted planar PSCs ...

Quantitative analysis of SOX2 and OCT4 expression in pluripotency and differentiation

Daniel Strebinger

Embryonic stem (ES) cells have the capacity to give rise to all cell types of the adult organism and can be used as a model to study early cell fate decisions as they closely recapitulate in vivo events. The M and G1 phases have been suggested to be the ke ...

Multi-axial self-organization properties of mouse embryonic stem cells into gastruloids

Denis Duboule, Matthias Lütolf, Leonardo Beccari, Mehmet Ugur Girgin, Anne-Catherine Cossy, Alfonso Martinez Arias

The emergence of multiple axes is an essential element in the establishment of the mammalian body plan. This process takes place shortly after implantation of the embryo within the uterus and relies on the activity of gene regulatory networks that coordina ...

Machine Learning Identifies Stemness Features Associated with Oncogenic Dedifferentiation

Jia Liu, Jian Wang, Wei Zhang, Jun Li, Min Wang, Wei Li, Hui Shen, Li Ding, Yi Han, Phuong Nguyen, Han Liang, Luca Mattei

Cancer progression involves the gradual loss of a differentiated phenotype and acquisition of progenitor and stem-cell-like features. Here, we provide novel stemness indices for assessing the degree of oncogenic dedifferentiation. We used an innovative one ...

High Open Circuit Voltage for Perovskite Solar Cells with S,Si-Heteropentacene-Based Hole Conductors

Michael Graetzel, Shaik Mohammed Zakeeruddin, Mohammad Ibrahim Dar, Amaresh Mishra, Neha Arora

High photovoltage in perovskite solar cells (PSCs) can be achieved by designing new hole transporting materials (HTMs) with relatively deeper energy levels of the highest occupied molecular orbital (HOMO). Here, we report on the synthesis of a new heteroac ...

WDR79/TCAB1 plays a conserved role in the control of locomotion and ameliorates phenotypic defects in SMA models

Brian Donal McCabe

SMN (Survival Motor Neuron) deficiency is the predominant cause of spinal muscular atrophy (SMA), a severe neurodegenerative disorder that can lead to progressive paralysis and death. Although SMN is required in every cell for proper RNA metabolism, the re ...

Advanced technologies to control stem-cell based organogenesis

Nathalie Brandenberg

Organoids represent the first in vitro cell culture systems that closely resemble native tissues in terms of cellular composition, architecture and key aspects of physiology. Through the discovery of these cultures, researchers could demonstrate that stem ...

Perovskite solar cells with CuSCN hole extraction layers yield stabilized efficiencies greater than 20%

Michael Graetzel, Shaik Mohammed Zakeeruddin, Mohammad Ibrahim Dar, Neha Arora, Norman Pellet

Perovskite solar cells (PSCs) with efficiencies greater than 20% have been realized only with expensive organic hole-transporting materials. We demonstrate PSCs that achieve stabilized efficiencies exceeding 20% with copper(I) thiocyanate (CuSCN) as the ho ...
