Hierarchically engineered fibrous scaffolds for bone regeneration

Nov 6, 2013 - Surface properties of biomaterials play a major role in the governing of cell functionalities. It is well known that mechanical, chemical and nanotopographic cues, for example, influence cell proliferation and differentiation. Here, we present a

Flower development: from morphodynamics to morphomechanics

May 19, 2017 - The shoot apical meristem (SAM) is a small population of stem cells that continuously generates organs and tissues. We will discuss here flower formation at the SAM, which involves a complex network of regulatory genes and signalling molecules. A

Stiffness gradients in vascular bundles of the palm Washingtonia robusta

Jul 1, 2008 - Palms can grow at sites exposed to high winds experiencing large dynamic wind and gust loads. Their stems represent a system of stiff fibrous elements embedded in the soft parenchymatous tissue. The proper design of the interface of the stiffening

Gene transfer therapy for heritable disease: cell and expression targeting

Feb 27, 1993 - Gene therapy is defined as the delivery of a functional gene for expression in somatic tissues with the intent to cure a disease. Different gene transfer strategies may be required to target different tissues. Adenosine deaminase (ADA) deficiency is

Mapping the route from naive pluripotency to lineage specification

Dec 5, 2014 - In the mouse blastocyst, epiblast cells are newly formed shortly before implantation. They possess a unique developmental plasticity, termed naive pluripotency. For development to proceed, this naive state must be subsumed by multi-lineage

Dynamics of haemopoiesis across mammals

Jul 15, 2008 - Haemopoiesis is a fundamental physiologic process found in many animals. Among mammals, the diversity in size and function required suitable adaptations of this process. In this work, we use allometric principles to determine whether this required a

The influence of the corticothalamic projection on responses in thalamus and cortex

Dec 29, 2002 - We review results on the in vivo properties of neurons in the dorsal lateral geniculate nucleus (dLGN) that receives its afferent input from the retina and projects to the visual cortex. In addition, the dLGN receives input from the brain stem and

A human iPSC line capable of differentiating into functional macrophages expressing ZsGreen: a tool for the study and…

Jul 5, 2018 - We describe the production of a human induced pluripotent stem cell (iPSC) line, SFCi55-ZsGr, that has been engineered to express the fluorescent reporter gene, ZsGreen, in a constitutive manner. The CAG-driven ZsGreen expression cassette was

Mutation rates and the evolution of germline structure

Jul 19, 2016 - Genome sequencing studies of de novo mutations in humans have revealed surprising incongruities in our understanding of human germline mutation. In particular, the mutation rate observed in modern humans is substantially lower than that estimated

In medio stat virtus: unanticipated consequences of telomere dysequilibrium

Mar 5, 2018 - The integrity of chromosome ends, or telomeres, depends on myriad processes that must balance the need to compact and protect the telomeric, G-rich DNA from detection as a double-stranded DNA break, and yet still permit access to enzymes that process
