The Developmental Control of Transposable Elements and the Evolution of Higher Species

Transposable elements (TEs) account for at least 50% of the human genome. They constitute essential motors of evolution through their ability to modify genomic architecture, mutate genes and regulate gene expression. Accordingly, TEs are subject to tight e ...

Possibilities in Germ Cell Research: An Engineering Insight

Omid Mashinchian, Morteza Mahmoudi

Germ cells (GCs) are responsible for fertility and disruptions in their development or function cause infertility. However, current knowledge about the diverse mechanisms involved in GC development and function is still in its infancy. This is mainly becau ...

Dynamic Reorganization of Extremely Long-Range Promoter-Promoter Interactions between Two States of Pluripotency

Pierre Raymond Fabre

Serum-to-2i interconversion of mouse embryonic stem cells (mESCs) is a valuable in vitro model for early embryonic development. To assess whether 3D chromatin organization changes during this transition, we established Capture Hi-C with target-sequence enr ...

Biomechanical forces promote blood development through prostaglandin E2 and the cAMP-PKA signaling axis

Olaia Maria Naveiras Torres-Quiroga, Nan Li

Blood flow promotes emergence of definitive hematopoietic stem cells (HSCs) in the developing embryo, yet the signals generated by hemodynamic forces that influence hematopoietic potential remain poorly defined. Here we show that fluid shear stress endows ...

PC7 and the related proteases Furin and Pace4 regulate E-cadherin function during blastocyst formation

Daniel Constam, Sylvain Frédéric Bessonnard

The first cell differentiation in mammalian embryos segregates polarized trophectoderm cells from an apolar inner cell mass (ICM). This lineage decision is specified in compacted morulae by cell polarization and adhesion acting on the Yes-associated protei ...

Evolutionally dynamic control of LINE-1 elements in embryonic stem cells

Natali Pennese

Mobile elements are important evolutionary forces that challenge genomic integrity. Long interspersed element-1 (L1, also known as LINE-1) is the only autonomous transposon still active in the human genome. It displays an unusual pattern of evolution, with ...

MATHICSE Technical Report : Isogeometric approximation of cardiac electrophysiology models on surfaces: an accuracy study with application to the human left atrium

Alfio Quarteroni, Luca Dede', Toni Mikael Lassila, Andrea Bartezzaghi, Alessandro Samuele Patelli

We consider Isogeometric Analysis in the framework of the Galerkin method for the spatial approximation of cardiac electrophysiology models defined on NURBS surfaces; specifically, we perform a numerical comparison between basis functions of degree p≥1and ...

Tbx6, Mesp-b and ripply1 regulate the onset of skeletal myogenesis in zebrafish

Andrew Charles Oates

During embryonic development, the paraxial mesoderm becomes segmented into somites, within which proliferative muscle progenitors and muscle fibers establish the skeletal musculature. Here, we demonstrate that a gene network previously implicated in somite ...

Culture of preantral follicles in poly(ethylene) glycol-based, three-dimensional hydrogel: a relationship between swelling ratio and follicular developments

Jeffrey Alan Hubbell, Seung Tae Lee

This study was undertaken to examine how the softness of poly(ethylene) glycol (PEG)-based hydrogels, creating a three-dimensional (3D) microenvironment, influences the in vitro growth of mouse ovarian follicles. Early secondary, preantral follicles of 2we ...

Photothermal cellular stimulation in functional bio-polymer interfaces

Diego Ghezzi

Hybrid interfaces between organic semiconductors and living tissues represent a new tool for in-vitro and in-vivo applications, bearing a huge potential, from basic researches to clinical applications. In particular, light sensitive conjugated polymers can ...
