title: A new technique to study the mechanical properties of collagen lattices.
abstract: A new technique to study the mechanical properties of collagen lattices or dermal equivalents is described. With the help of the load-extension curve obtained with a uniaxial traction apparatus, a stiffness modulus varying from 0.06 to 1 MPa is calculated from the studied parameters (duration of culture, collagen and fibroblast concentration). The technique is presented as a new tool for testing the effect of pharmacological agents on the mechanical properties of the skin.
