Modeling hematopoietic stem cell dynamics in bioengineered niches

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 ...

Brain Perfusion Measurements Using Multidelay Arterial Spin-Labeling Are Systematically Biased by the Number of Delays

Dimitri Nestor Alice Van De Ville, Nicolas Gninenko, Merel Margaretha van der Thiel

BACKGROUND AND PURPOSE:Multidelay arterial spin-labeling is a promising emerging method in clinical practice. The effect of imaging parameters in multidelay arterial spin-labeling on estimated cerebral blood flow measurements remains unknown. We directly c ...

Linking toxicity and adaptive responses across the transcriptome, proteome, and phenotype of Chlamydomonas reinhardtii exposed to silver

Kristin Schirmer, Laura Sigg, Renata Behra

Understanding mechanistic and cellular events underlying a toxicological outcome allows the prediction of impact of environmental stressors to organisms living in different habitats. A systems-based approach aids in characterizing molecular events, and the ...

A Subpopulation of Smooth Muscle Cells, Derived from Melanocyte-Competent Precursors, Prevents Patent Ductus Arteriosus

Friedrich Beermann

Background: Patent ductus arteriosus is a life-threatening condition frequent in premature newborns but also present in some term infants. Current mouse models of this malformation generally lead to perinatal death, not reproducing the full phenotypic spec ...

Delayed cortical impairment following lipopolysaccharide exposure in preterm fetal sheep

Yohan Van de Looij, François Lazeyras

Preterm infants exhibit chronic deficits in white matter (WM) and cortical maturation. Although fetal infection/inflammation may contribute to WM pathology, the factors contributing to cortical changes are largely unknown. We examined the effect of fetal l ...

Engineering of living autologous human umbilical cord cell-based septal occluder membranes using composite PGA-P4HB matrices

Peter Modregger, Marco Stampanoni

Interventional closure of intracardiac wall defects using occluder devices has evolved as a highly attractive treatment option. However, incomplete and delayed healing reactions often result in a major risk of residual defects, thromboembolism, or device f ...

Human fetal bone cells in delivery systems for bone engineering

Dominique Pioletti, Corinne Scaletta, Sandra Jaccoud, Nathalie Hirt-Burri

The aim of this study was to culture human fetal bone cells (dedicated cell banks of fetal bone derived from 14 week gestation femurs) within both hyaluronic acid gel and collagen foam, to compare the biocompatibility of both matrices as potential delivery ...

A novel lentiviral vector targets gene transfer into human hematopoietic stem cells in marrow from patients with bone marrow failure syndrome and in vivo in humanized mice

Didier Trono

In vivo lentiviral vector (LV)-mediated gene delivery would represent a great step forward in the field of gene therapy. Therefore, we have engineered a novel LV displaying SCF and a mutant cat endogenous retroviral glycoprotein, RDTR. These RDTR/SCF-LVs o ...

An assessment of ductus venosus tapering and wave transmission from the fetal heart

Nikolaos Stergiopoulos

Pressure and flow pulsations in the fetal heart propagate through the precordial vein and the ductus venosus (DV) but are normally not transmitted into the umbilical vein (UV). Pulsations in the umbilical vein do occur, however, in early pregnancy and in p ...

Optimization of in vitro cord blood hematopoietic stem cell expansion through the identification of secreted factors mediating inter-cellular communication

Aline Roch

Robust and large-scale expansion of umbilical cord blood stem cells in vitro is necessary for widening the usage of transplantation therapies for the treatment of hematological and immune diseases. The lack of understanding of the complex inter-cellular ne ...
