how can i make the link betwen fluid flow and stress change?
What kind of link do you want to make? Pressure can generate mechanical stress in pipes or the interaction between fluid and solids. Please review the next videos:

As pressure build up within the fluid due to more pumping, or chemical or physical process, the fluid force will remain, = F = pressure * area,
Thank you, but what i realy mean, is how a model of stress change give me the fluid flow ?
I hope not to misunderstand your question,
the momentum equation and the subsequent equations like Bernoulli, Naiver Stokes and model the fluid slows and direct and shear stresses.
Instead of checking only the mRNA level, I want to check the active protein level of MMP-1 in Liver tissue from mice. How can I do that?
