Impact of germline susceptibility variants in cancer genetic studies [PDF]
arXiv, 2016 Although somatic mutations are the main contributor to cancer, underlying germline alterations may increase the risk of cancer, mold the somatic alteration landscape and cooperate with acquired mutations to promote the tumor onset and/or maintenance.

CeiTEA: Adaptive Hierarchy of Single Cells with Topological Entropy
Advanced Science, EarlyView.CeiTEA, a novel hierarchical clustering algorithm based on topological entropy, effectively captures complex structures underlying data. By constructing an adaptive multi‐nary partition tree, CeiTEA reveals hierarchical structures and local diversifications, outperforming existing methods in clustering accuracy and consistency and providing the ...

In vitro regeneration of some Iranian alfalfa (Medicago sativa L.) genotypes via somatic embryogenesis [PDF]
Zīst/shināsī-i Giyāhī-i Īrān, 2014 An effective in vitro regeneration system is one of the prerequisites for genetic manipulation of alfalfa (Medicago sativa L.) varieties and genotypes. In this research, somatic embryogenesis of four alfalfa genotypes, 6-18 (synthetic), 4-14 (Kara Yonje-

On the evolution of differentiated multicellularity [PDF]
arXiv, 2008 Most conspicuous organisms are multicellular and most multicellular organisms develop somatic cells to perform specific, non-reproductive tasks. The ubiquity of this division of labor suggests that it is highly advantageous. In this paper, I present a model to study the evolution of specialized cells.

Advanced Proteomic Approaches to Elucidate Somatic Embryogenesis
Frontiers in Plant Science, 2018 Somatic embryogenesis (SE) is a cell differentiation process by which a somatic cell changes its genetic program and develops into an embryonic cell. Investigating this process with various explant sources in vitro has allowed us to trace somatic embryo ...

Biomimetic Chemotactic Motion of Self‐Assembling Doublet Microrobots
Advanced Intelligent Systems, EarlyView.This article studies the shape‐dependent chemotaxis of different morphologies including self‐assembled doublet microswimmers that exhibit autonomous movement in hydrogen peroxide H2O2 gradients. Without the need for complex material preparation a novel type of chemotactic active matter is produced, which allows the separation of propulsion and cargo ...

Drosophila embryogenesis scales uniformly across temperature in developmentally diverse species [PDF]
arXiv, 2013 Temperature affects both the timing and outcome of animal development, but the detailed effects of temperature on the progress of early development have been poorly characterized. To determine the impact of temperature on the order and timing of events during Drosophila melanogaster embryogenesis, we used time-lapse imaging to track the progress of ...

The Biophysical Micro-Environment's Influence on Cell Fate Decisions During Macrophage Activation and Somatic Cell Reprogramming [PDF]
arXiv, 2020 Cells are known to sense and respond to their mechanical microenvironment in profound ways. Various evidence has implicated the adhesome, a body of adhesion associated proteins, in several cell fate decisions, including differentiation and proliferation.
