简介：
Overview
This protocol exposes cancer cells in a suspension to brief pulses of fluid shear stress to mimic certain aspects of how metastatic cancer cells are exposed to hemodynamic forces while they're in the circulatory system. It is a relatively simple technique to apply brief pulses of high level fluid shear stress.

What is fluid shear stress?
Fluid shear stress refers to the force per unit area exerted by fluid flow on a surface, which can affect cell behavior.
Why is it important to study circulating tumor cells?
Studying circulating tumor cells helps understand metastasis and the mechanisms of cancer spread in the body.
What precautions should be taken during the experiment?
Use appropriate safety measures to handle aerosols and ensure proper handling of uncapped needles.
How does this method mimic the circulatory system?
The method applies brief pulses of fluid shear stress similar to what cancer cells experience in blood flow.
What type of cancer cells are used in this protocol?
PC3 prostate cancer cells are used in this study to model the effects of hemodynamic stress.
Can this method be applied to other types of cancer cells?
Yes, this method can potentially be adapted for other cancer cell types to study their response to shear stress.
