Elastic Energy Storage in Biological Materials: Internal Stresses and Their Functionality

open access: yesAdvanced Materials, EarlyView.
Harnessing and storing internally generated elastic energy is a clever strategy by biological materials to perform functions like shape transformation, movement, and predation. This review explores how biological systems manipulate mechanisms like atomic or protein integration into minerals, protein conformational shifts, phase transitions, and osmotic

Myosin II-mediated cell shape changes and cell intercalation contribute to primitive streak formation

open access: yesNature Cell Biology, 2015
Primitive streak formation in the chick embryo involves large-scale highly coordinated flows of more than 100,000 cells in the epiblast. These large-scale tissue flows and deformations can be correlated with specific anisotropic cell behaviours in the ...

On Myosin II dynamics in the presence of external loads

open access: yes, 2005
We address the controversial hot question concerning the validity of the loose coupling versus the lever-arm theories in the actomyosin dynamics by re-interpreting and extending the phenomenological washboard potential model proposed by some of us in a ...

Tailored Xenogeneic‐Free Polymer Surface Promotes Dynamic Migration of Intestinal Stem Cells

open access: yesAdvanced Materials, EarlyView.
This study introduces a PoLymer‐coated Ultra‐stable Surface (PLUS), a nitrogen plasma‐treated poly(ethyleneglycoldimethacrylate), as a stable xenogeneic‐free platform for intestinal stem cell culture. PLUS enhances cell attachment, supports actin‐driven migration, and retains functionality after 3 years of storage. Promoting cytoskeletal reorganization,

Macrophages Mediate Mesoscale Brain Mechanical Homeostasis

open access: yesAdvanced Materials, EarlyView.
We investigated the role of infiltrating immune cells in sculpting the developing brain. Using Brillouin microscopy and active microrheology, we found microglia actively maintain tissue viscoelasticity. Moreover, colony stimulating factor one receptor (CSF1R)‐driven stromal remodeling alters brain mechanics in vivo. These findings link immune activity,

SE-HPLC separation of myosin complex with tannins from bearberries (Arctostaphylos uva-ursi L. Sprengel) leaves - a short report.

open access: yesCzech Journal of Food Sciences, 2009
Phenolic compounds were extracted from bearberry (Arctostaphylos uva-ursi L. Sprengel) leaves into 95% (v/v) ethanol. The tannin constituents were separated from the crude extract using Sephadex LH-20 column chromatography with 95% (v/v) ethanol and 50% (

Integrin α8‐Mediated Pericyte Morphogenesis Controls Blood‐Brain Barrier Integrity

open access: yesAdvanced Science, EarlyView.
This study highlights that ITGA8 impacts pericyte morphology and function, both crucial for BBB integrity, via RhoA/ROCK signaling, thus influencing TGF‐β1 activation through cytoskeletal tension and ECM interactions. Notably, in post‐ischemic recovery models, ITGA8 deficiency exacerbates vascular dysfunction by impairing pericyte‐mediated BBB ...

Non-muscle myosin IIB is critical for nuclear translocation during 3D invasion

open access: yesJournal of Cell Biology, 2015
Non-muscle myosin IIB plays a major role in applying force on the nucleus to facilitate nuclear translocation through tight spaces during 3D invasive migration, while non-muscle myosin IIA is critical for generating force during active protrusion.
