Article Synopsis
- Plant and animal cells have developed different strategies for their growth, but how their cell mechanics compare has not been clear due to separate experimental setups.
- This study used the same equipment to examine the rheology (flow behavior) of both types of cells and found that wall-less plant cells behave similarly to animal cells in terms of their mechanical properties.
- The researchers discovered that while microtubules influenced the plant cells' rheology, the animal cells relied more on their actin networks, suggesting that both have evolved distinct molecular strategies to achieve similar mechanical characteristics.
Dual-frequency transducer for nonlinear contrast agent imaging.
IEEE Trans Ultrason Ferroelectr Freq Control
December 2013
Detection of high-order nonlinear components issued from microbubbles has emerged as a sensitive method for contrast agent imaging. Nevertheless, the detection of these high-frequency components, including the third, fourth, and fifth harmonics, remains challenging because of the lack of transducer sensitivity and bandwidth. In this context, we propose a new design of imaging transducer based on a simple fabrication process for high-frequency nonlinear imaging.

Living cells sense the rigidity of their environment and adapt their activity to it. In particular, cells cultured on elastic substrates align their shape and their traction forces along the direction of highest stiffness and preferably migrate towards stiffer regions. Although numerous studies investigated the role of adhesion complexes in rigidity sensing, less is known about the specific contribution of acto-myosin based contractility.
