Biomimetic Fibrinogen Nanofiber Scaffolds for Vascular Hematopoietic Stem Cell Niche Engineering

open access: yesAdvanced Healthcare Materials, EarlyView.
This study presents an advanced in vitro model of the vascular hematopoietic stem cell niche using self‐assembled fibrinogen nanofibers, mimicking the basement membrane in bone marrow (BM) sinusoids. The model supports the coculture of microvascular endothelial cells, stromal cells, and hematopoietic stem and progenitor cells, providing insights into ...

Synthetic Cell‐Based Tissues for Bottom‐Up Assembly of Artificial Lymphatic Organs

open access: yesAdvanced Healthcare Materials, EarlyView.
Synthetic cells have emerged as a novel biomimetic approach for fundamental research and therapeutic interventions. T cell activating synthetic cells are able to form 3D tissue‐like structures by self‐assembly into lymphatic bottom‐up tissues (lymphBUT) with tunable biochemical and biomechanical functionalities as well as metabolic activity are ...

5σ tension between Planck cosmic microwave background and eBOSS Lyman-alpha forest and constraints on physics beyond ΛCDM

open access: yesPhysical Review Research
We find that combined Planck cosmic microwave background, baryon acoustic oscillations, and supernovae data analyzed under Λ cold dark matter (ΛCDM) are in 4.9σ tension with the extended Baryon Oscillation Spectroscopic Survey (eBOSS) Lyα forest in ...

Natural X-ray lines from the low scale supersymmetry breaking

open access: yesPhysics Letters B, 2015
In the supersymmetric models with low scale supersymmetry (SUSY) breaking where the gravitino mass is around keV, we show that the 3.5 keV X-ray lines can be explained naturally through several different mechanisms: (I) a keV scale dark gaugino plays the

Geometrical Designs in Volumetric Bioprinting to Study Cellular Behaviors in Engineered Constructs

open access: yesAdvanced Healthcare Materials, EarlyView.
Curvature and spatial confinement guide cell behavior in volumetrically printed 3D constructs. Endothelial cells align and spread along specific geometries, while metastatic osteosarcoma cells proliferate independently of structural cues. Label‐free holographic microscopy captures real‐time, long‐term cell–material interactions, highlighting Gel‐PEG's ...

Warm Dark Matter Sterile Neutrinos in Electron Capture and Beta Decay Spectra

open access: yesAdvances in High Energy Physics, 2016
We briefly review the motivation to search for sterile neutrinos in the keV mass scale, as dark matter candidates, and the prospects to find them in beta decay or electron capture spectra, with a global perspective.

Self‐Assembling Peptide Hydrogels Support Stromal Vascular Fraction Viability to Promote In Vivo Nerve Regeneration

open access: yesAdvanced Healthcare Materials, EarlyView.
Stromal vascular fraction (SVF) may enhance nerve repair, especially when delivered in a self‐assembling peptide hydrogel (SAPH). In vitro, softer SAPH increased neuronal explant outgrowth and supported greater SVF viability and proliferation. In a rat sciatic defect, SVF in an optimized SAPH produced motor and sensory recovery equivalent to autograft ...

Opening a new window for warm dark matter

open access: yes, 2006
We explore the range of parameters for dark-matter sterile neutrinos in an extention of the Minimal Standard Model by three singlet fermions with masses below the electroweak scale (the $\nu$MSM).
