| Research Abstract |
Vascular elastic fibers play a very important role in maintaining the structure of the arteries. The impairment of elastic fiber formation is closely related with aging and vascular diseases. We hypothesized that mecanical stresses onto the arteries would affect elastic fiber formation. Therefore, we tried to perform the quantitative analysis of the relation between elastic fiber formation and the types and strength of mechanical stresses. We found that elastic fiber formation was promoted in multi-layers of smooth muscle cells or by cycle stretch.
