Journal ArticleDOI

TL;DR: It is observed that preaggregation of the cells into spheroidal structures prior to seeding improved the morphogenesis of tissue structure and maintenance of viability.
Journal ArticleDOI
Anomalous diffusion and non-Gaussian velocity distribution of Hydra cells in cellular aggregates
TL;DR: In this article, the center of mass motion of single endodermal Hydra cells in two kinds of cell-to-cell aggregates was studied and it was shown that cell motion in two-dimensional cellular aggregates can be described by a correlated-type anomalous diusion.
Journal ArticleDOI
Probing polymerization forces by using actin-propelled lipid vesicles.

TL;DR: The results indicate that actin exerts retractile or propulsive forces depending on the local membrane curvature and that the membrane is strongly bound to the actin gel, consistent with the observed dynamics.
Journal ArticleDOI
Cytoskeletal forces during signaling activation in Jurkat T-cells.
TL;DR: Whereas actin dynamics were essential for force generation, myosin contractility played a limited role, and T-cells were also found to be mechanosensitive.
Journal ArticleDOI
Neutrophil chemorepulsion in defined interleukin‐8 gradients in vitro and in vivo
William G. Tharp,Rashmi Yadav,Daniel Irimia,Arpita Upadhyaya,Azadeh Samadani,O. Hurtado,S-Y. Liu,S. Munisamy,Diana M. Brainard,M. J. Mahon,Sussan Nourshargh,A. van Oudenaarden,M. G. Toner,Mark C. Poznansky +13 more
TL;DR: The finding that neutrophils undergo chemorepulsion in response to continuous chemokine gradients expands the paradigm by which neutrophil migration is understood and may reveal a novel approach to the authors' understanding of the homeostatic regulation of inflammation.
