Role of cell deformability in the two-dimensional melting of biological tissues
, 2018 The size and shape of a large variety of polymeric particles, including biological cells, star polymers, dendrimes, and microgels, depend on the applied stresses as the particles are extremely soft.

Loss of N-Cadherin Expression in Tumor Transplants Produced From As+3- and Cd+2-Transformed Human Urothelial (UROtsa) Cell Lines. [PDF]
PLoS ONE, 2016 BACKGROUND:Epithelial to mesenchymal transition is a process in which a cell experiences a loss of epithelial cell characteristics and acquires a more mesenchymal cell phenotype.

Temperature Dependence Cancellation of the Cs Clock Frequency in the Presence of Ne Buffer Gas
, 2011 The temperature dependence of the Cs clock transition frequency in a vapor cell filled with Ne buffer gas has been measured. The experimental setup is based on the coherent population trapping (CPT) technique and a temporal Ramsey interrogation allowing ...

Active wetting of epithelial tissues
, 2019 Development, regeneration and cancer involve drastic transitions in tissue morphology. In analogy with the behavior of inert fluids, some of these transitions have been interpreted as wetting transitions.

Selective advantage for multicellular replicative strategies: A two-cell example [PDF]
, 2005 This paper develops a quasispecies model where cells can adopt a two-cell survival strategy. Within this strategy, pairs of cells join together, at which point one of the cells sacrifices its own replicative ability for the sake of the other cell.

MYB64 and MYB119 are required for cellularization and differentiation during female gametogenesis in Arabidopsis thaliana. [PDF]
PLoS Genetics, 2013 In angiosperms, the egg cell forms within the multicellular, haploid female gametophyte. Female gametophyte and egg cell development occurs through a unique process in which a haploid spore initially undergoes several rounds of synchronous nuclear ...

Plants, 2023 Epithelial-to-mesenchymal transition (EM transition) is a process wherein epithelial cells lose their intrinsic characteristics and cell–cell junctions and differentiate into a mesenchymal phenotype.

Nature Communications, 2021 The role of the nucleolus in cell fate is not well known. Here the authors show nucleolar integrity maintained by rRNA-mediated liquid-liquid phase separation and 3D chromatin structure of perinucleolar heterochromatin regulates the fate transition of ...

eLife, 2022 How a cell changes from one stable phenotype to another one is a fundamental problem in developmental and cell biology. Mathematically, a stable phenotype corresponds to a stable attractor in a generally multi-dimensional state space, which needs to be ...
