Direct Ink Writing of Conductive Hydrogels
Advanced Functional Materials, EarlyView.This review examines the use of direct ink writing (DIW) for fabricating conductive hydrogels with customizable 3D structures. It outlines the rheological requirements for successful DIW, followed by an exploration of the materials and ink formulations used to impart electronic and/or ionic conductivity to hydrogels while maintaining printability ...

Optimization of Buffalo (Bubalus bubalis) Embryonic Stem Cell Culture System
Cell Journal, 2015 Objective: In order to retain an undifferentiated pluripotent state, embryonic stem (ES) cells have to be cultured on feeder cell layers. However, use of feeder layers limits stem cell research, since experimental data may result from a combined ES ...

Gradual approximation of the domain of attraction by gradual extension of the "embryo" of the transformed optimal Lyapunov function [PDF]
arXiv, 2002 In this paper an autonomous analytical system of ordinary differential equations is considered. For an asymptotically stable steady state x0 of the system a gradual approximation of the domain of attraction DA is presented in the case when the matrix of the linearized system in x0 is diagonalizable.

The Embryo Sac and Embryo of Gnetum gnemon [PDF]
Botanical Gazette, 1908 1. The "antipodal tissue" described by Lotsy as occurring in Gnetum Gnemon at the fertilization stage is a sharply differentiated nutritive tissue developed in the nucellus beneath the embryo sac, which at this stage contains only free nuclei, as described for other species of Gnetum. 2.

Advanced Functional Materials, EarlyView.Glioblastoma multiforme is the most devastating and incurable brain tumor. To better study this disease, a 3D model is developed using a hyaluronic acid‐based hydrogel combined with a multicellular approach. This model recapitulates in vivo brain stiffness, cell‐extracellular matrix and cell‐cell interactions and the tumor's hijacking function with the

Chiral Engineered Biomaterials: New Frontiers in Cellular Fate Regulation for Regenerative Medicine
Advanced Functional Materials, EarlyView.Chiral engineered biomaterials can selectively influence cell behaviors in regenerative medicine. This review covers chiral engineered biomaterials in terms of their fabrication methods, cellular response mechanisms, and applications in directing stem cell differentiation and tissue function.

Embryo staging with weakly-supervised region selection and dynamically-decoded predictions [PDF]
arXiv, 2019 To optimize clinical outcomes, fertility clinics must strategically select which embryos to transfer. Common selection heuristics are formulas expressed in terms of the durations required to reach various developmental milestones, quantities historically annotated manually by experienced embryologists based on time-lapse EmbryoScope videos.

Advanced Functional Materials, EarlyView.In this work, melt electrowriting is used to fabricate a 3D printed scaffold design that generates engineered cardiac tissues with in‐plane contraction, mimicking natural myocardium. It is shown that these tissues display advanced maturation and functionality.
