In the physiological and pathological activities of collagenous soft tissues, the fibroblasts in various phenotypes coordinate in response to the regulation, proliferation, differentiation, and remodeling of the tissue. To understand the tissue-to-cell stress transfer, understanding factors contributing to the stress distribution at organ-tissue-cell levels is of paramount importance.
