Geometry-Encoded Microtrenches Stabilize Endothelium on High Shear Biomaterial Surfaces

This paper demonstrates that engineered microtrench geometries on biomaterial surfaces reduce shear stress and enhance endothelial cell retention and function under high shear conditions.

Finite afterload during asymmetrically cycled preload promotes fetal ventricular growth, maturation, and contractile function while suppressing fibrotic remodeling

The paper investigates how asymmetrically cycled preload with low afterload promotes fetal ventricular growth, maturation, and contractile function while reducing fibrosis in chick myocardial tissue.

Directional bone matrix mineralization in the CAM assay is governed by vascular integration and matrix remodeling

The paper investigates bone matrix mineralization in the CAM assay, finding that vascular integration and matrix remodeling govern mineral deposition.

Kinemomics: spatiotemporal morphodynamic mapping of ventricular kinematic subpopulations in organotypic fetal heart slices

The paper introduces Kinemomics, a framework to map spatiotemporal kinematic states in fetal heart tissue, revealing developmental and malformation dynamics.

Longitudinal Live Imaging Derived 4D Hemodynamics and Dynamic Tissue Mechanics Across Outflow Tract Morphogenesis

The paper uses 4D CFD simulations to study hemodynamics and tissue mechanics in the cardiac outflow tract during development, revealing correlations between wall shear stress and tissue extension.

Spatiotemporal Atlas of Heart Development Reveals Blood-Flow-Dependent Cellular, Structural, Metabolic, and Spatial Remodeling

The paper generates a spatiotemporal atlas of heart development using flow perturbations and spatial transcriptomics to study how blood flow affects cellular, structural, and metabolic remodeling.

Valve endothelial monolayer fissuring via RhoA activity induces 3D calcific aortic valve lesion emergence as revealed by a longitudinal live-imaging platform

This paper develops a live-imaging platform to study calcific aortic valve disease onset and identifies RhoA activity as a key driver of lesion formation.

Shear and hydrostatic stress regulate fetal heart valve remodeling through YAP-mediated mechanotransduction

This study investigates how shear and hydrostatic stress regulate fetal heart valve remodeling through YAP-mediated mechanotransduction in chick embryos.

Uncovering Transcriptional Dark Matter via Gene Annotation Independent Single-Cell RNA Sequencing Analysis

The paper introduces a method to uncover transcriptionally active regions in scRNA-seq data beyond standard gene annotations, improving transcriptome coverage in understudied organisms.

Spatiotemporal single-cell RNA sequencing of developing hearts reveals interplay between cellular differentiation and morphogenesis

This study uses spatiotemporal single-cell RNA sequencing to analyze chicken heart development, revealing the interplay between cellular differentiation and morphogenesis.

Experimental-based Computational Modeling Distinguishes Early Cardiac Outflow Tract Compensation Mechanisms

The paper combines experimental and computational modeling to study how abnormal hemodynamics affect cardiac outflow tract development and identify compensation mechanisms.

Population heterogeneity in the epithelial to mesenchymal transition is controlled by NFAT and phosphorylated Sp1

The paper develops a mathematical model of EMT regulation, identifies NFAT and phosphorylated Sp1 as master regulators, and shows that dual TGF-{beta} and VEGF-A exposure leads to phenotypic heterogeneity.
