Structural dynamics of the fibrous basis of the reparative regenerate during spontaneous skin wound healing comprises multiple stages, it successively transforms from one organization level to another more complex level, forms a multilevel 3D structure including molecular, supramolecular, fibrillar, fiber, and tissue elements. The formed reparative regenerate is integrated with the preserved skin, together they have common fibrous basis consisting of three parts that are different in organization of fibrous structures: atypical (central), tissue organospecific (peripheral), and transitional.
Keywords: fibrogenesis; reparative regenerative structure; skin wound; spontaneous healing.
