Recent researches on the responses of fibroblasts exposed to cyclic mechanical stretching in vitro / 生物医学工程学杂志

ABSTRACT

Recently, in vitro dynamical cell-culture has been drawing more and more attention from researchers in the areas of tissue engineer, and a series of researches have demonstrated that cyclic mechanical stretching has significant effects on the cell proliferation, differentiation, and on the cell alignment on scaffold, as well as on the synthesis of extracellular matrix, cytokines, and matrix metalloproteinases (MMPs). By focusing on reviewing the culture of several kinds of fibroblasts in vitro, we learned that these cellular responses mentioned above induced by cyclic mechanical stretching were tested by many precisely designed experiments, and assumed that cyclic mechanical stretching, if applied properly, would contribute significantly to our purpose of constructing more sophisticated tissue-engineered tendon and ligament.
