[Ultrastructure of human normal and pathological reassembled collagen fibers].
It is possible, in vitro, to break down human skin then reassemble the collagen fibres of the dermis, essentially type I collagen. The authors have developed a biophysical process for the manufacture of type I autocollagen. They present the electron microscopic study of this collagen. These healthy collagen fibres are compared with the fibres obtained from radiation dermatitis skin and keloid scars. Major ultrastructural differences are demonstrated.
