Data from: Microparticle-mediated VZV propagation and endothelial activation: mechanism of VZV vasculopathy
Objective: Varicella zoster virus (VZV) can spread anterogradely and infect cerebral arteries causing VZV vasculopathy and arterial ischaemic stroke (AIS). In this study we tested the hypothesis that virus-infected cerebrovascular fibroblasts undergo phenotypic changes that promote vascular remodeling and facilitate virus transmission in an in vitro model of VZV vasculopathy. The aims of this project were therefore: (i) to examine the changes that virus-infected Human brain adventitial vascular fibroblasts (HBVAF) undergo in an in vitro model of VZV vasculopathy; and to (ii) identify disease biomarkers relating to VZV related vasculopathy. Methods: HBVAF were infected with VZV, and their ability to migrate, proliferate, transdifferentiate and interact with endothelial cells was studied with flow cytometry. Microparticles (MP) released from these cells were isolated, and imaged with transmission electron microscopy; and their protein content analysed with mass spectrometry. Circulating MP profiles were also studied in children with VZV and non-VZV vasculopathy and compared with controls. Results: VZV-infected HBVAF transdifferentiated into myofibroblasts with enhanced proliferative and migratory capacity. Interaction of VZV-infected HBVAF with endothelial cells resulted in endothelial dysfunction. These effects were, in part, mediated by the release of MP from VZV infected HBVAF. These MP contained VZV virions that could transmit VZV to neighbouring cells, highlighting a novel model of VZV cell-to-cell viral dissemination. MP positive for VZV were significantly higher in children with VZV-related vasculopathy compared to children with non-VZV vasculopathy (p=0.01), and controls (p=0.007). Conclusions: VZV infected HBVAF promote vascular remodeling and facilitate virus transmission. These effects were mediated by the release of apoptotic MP that could transmit VZV infection to neighbouring cells, through a "Trojan Horse" means of productive viral infection. VZV+MP may represent a disease biomarker worthy of further study.

Data and Codes for: Segmentation uncertainty of vegetated porous media propagates during X-ray CT image-based analysis
<p>Phase segmentation is a crucial step in X-ray computed tomography (CT) for image-based analysis (CT-IBA) to derive soil and root information. How segmentation uncertainty (SU) affects CT-IBA of vegetated soil has never been explored. The enclosed data and codes are used to assist the analysis of SU quantification and propagation in the journal paper published in Plant & Soil. The title of the paper is Segmentation uncertainty of vegetated porous media propagates during X-ray CT image-based analysis. </p>
Self-propagating wave drives noncanonical antidurotaxis of skull bones in vivo
<p>Cell motility is a key feature of tissue morphogenesis, and it is thought to be driven primarily by the active migration of individual cells or collectives. However, this model is unlikely to apply to cells lacking overt cytoskeletal, stable cell-cell or cell-cell adhesions, and molecular polarity, such as mesenchymal cells. Here, by combining a novel imaging pipeline with biophysical modeling, we discover that during skull morphogenesis, a self-generated collagen gradient expands a population of osteoblasts towards a softer matrix. Biomechanical measurements revealed a gradient of stiffness and collagen along which cells move and divide. The moving cells generate an osteogenic front that travels faster than individual tracked cells, indicating that expansion is also driven by cell differentiation. Through biophysical modeling and perturbation experiments, we found that mechanical feedback between stiffness and cell fate drives bone expansion and controls bone size. Our work provides a mechanism for coordinated motion that does not rely upon the cytoskeletal dynamics of cell migration. We term this self-propagating motion down a stiffness gradient, noncanonical antidurotaxis. Identification of alternative mechanisms of cellular motion will help in understanding how directed cellular motility arises in complex environments with inhomogeneous material properties.</p>
