What the benefits of Negative Poisson's ratio materials and structures applications in Tissue engineering?
in short, depending on your specific application, i.e. the type of tissue or system you are trying to mimic, negative Poisson Ratio (NPR) helps to address problem of compliance mismatch.
some useful literature:

As you probably know, some tissues in the human, as well as animals like cats, have auxetic behavior. In this regard, I can mention the cancellous bone and cat skin.
Cancellous bone has a cellular microstructure that provides energy absorption in the bone, therefore by means of auxetic structure we want to mimic this property to gain faster and more durable healing for the patients.
