Darwin microfluidics shear stress
WebMay 1, 2024 · Shear stress levels are variable in tumor metastasis-related fluid microenvironment. Blood shear stress levels are higher than interstitial flow and lymph flow. Additionally, the FSS in hepatic sinusoid and central veins is 0.1-0.5 dyn/cm2and over 2 dyn/cm2, respectively. WebMar 14, 2024 · In microfluidic conditions, we observe that cell scavenging generates spatial gradients of H 2 O 2. High shear rates replenish H 2 O 2, abolish gradients, and generate a stress response. Combining mathematical simulations and biophysical experiments, we find that flow triggers an effect like "wind-chill" that sensitizes cells to H 2 O 2 ...
