Translational Microfluidics Laboratory

Bill presented recent work by Dr. Aw and Chloe on fluid mechanotransduction by the vascular endothelium to the NSF Center for Engineering Mechanobiology, headquartered at the University of Pennsylvania. It was good to see old friends and collaborators and to have a chance to discuss how mechanotransduction goes awry in vascular malformations.

Dr. Danica Dy, who recently defended her PhD in Dr. Rob Wirka's lab, published in Frontiers in Cardiovascular Medicine on the funcitonal role of TWIST1 in arterial smooth muscle. TWIST1 has been identified as a causal gene that increases risk for several vascular diseases, yet the molecular mechanisms remain unclear. Dr. Rathod from the Polacheck Lab helped to develop functional assays for smooth muscle cell migration that helped elucidate how TWIST1 modulates cellular phenot

Mitesh's work investigating the effects of blood pressure and flow on immune cell adhesion and migration across the endothelial wall in the context of chronic kidney disease was just published. The paper is entitled, "Microphysiological uremia model reveals biophysical potentiators of vascular dysfunction," and can be viewed via open access here . This work was gratiously supported by the UNC Institute for Convergent Science and continues a long-standing collaboration between

Dr. Polacheck publishes a perspective on a new method for measuring cell-generated forces in living tissues by high-resolution imaging of embedded force sensors. The perspective can be found here .

Wen's recent work investigating the formation and propagation of vascular malformations was chosen by the editor as an article to highlight in a special issue focused on Mechanomedicine. Wen and other members of the lab used microfluidic models of vascular malformations to understand how fluid transport and hemodynamics contributes to lesion growth and disease pathogenesis.

Awesome talk by an awesome post-bac in our lab, Aanya Sawhney on cell mechanics of vascular malformations in the vascular bioengineering session at BMES 2024 !

Dr. Polacheck receives a 2024 Young Innovator Award from the Cell and Molecular Bioengineering special interest group of the Biomedical Engineering Society based on the fantastic work of Chloe Whitworth.

Chloe gives an oral presentation on P300's modulation of endothelial mechanotransduction of fluid shear stress. Elizabeth gave a poster presentation on the generation of human vasculature-on-chip systems using cell-derived matrix hydrogels. Congratulations, Chloe and Elizabeth!
