AR3T supports the development of ex vivo and in vivo technologies that will enhance the understanding of stem cell response to stimulation.

Tissue loading is a powerful means for modulating the tissue microenvironment and promoting healing, a concept that serves as a cornerstone for Regenerative Rehabilitation research. A better understanding of the direct response of stem cells to extrinsic signals within the dynamic microenvironment will ultimately aid in the informed prescription of rehabilitation protocols for patients.

Stem cells interpret both electrical stimulation and mechanical forces in a broad spectrum of ways that can affect their behavior and, ultimately, their ability to drive tissue regeneration. Unfortunately, there are few in vitro or ex vivo methods currently available that allow for modeling and quantification of the direct effect of stimuli on stem cell behavior. There is, therefore, a need to develop ex vivo systems capable of modeling biologically relevant mechanical loads on stem cells in order to understand the mechanistic effects of physical forces on stem cell fate and function. There is also a need to accurately assess the effects of different types of forces experienced in vivo by endogenous stem cells existing within tissues or exogenous stem cell populations transplanted for regenerative therapies. The Regenerative Rehabilitation research community will benefit from the development of technologies that will enhance our understanding of stem cell responses to electrical and/or mechanical stimulation.
