Optimization of Buffalo (Bubalus bubalis) Embryonic Stem Cell Culture System

open access: yesCell 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]

open access: yesarXiv, 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.

Embryo staging with weakly-supervised region selection and dynamically-decoded predictions [PDF]

open access: yesarXiv, 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.

Multi-Task Deep Learning with Dynamic Programming for Embryo Early Development Stage Classification from Time-Lapse Videos [PDF]

open access: yesarXiv, 2019
Time-lapse is a technology used to record the development of embryos during in-vitro fertilization (IVF). Accurate classification of embryo early development stages can provide embryologists valuable information for assessing the embryo quality, and hence is critical to the success of IVF.
