Analysis of striae.

Striae proceed through stages quite similar to those in the evolution of scars. Most of the collagen bundles in the striae are highly stressed. Striae bear a striking resemblance to other human scar models in which newly synthesized connective tissue has been reorganized by tension. Unlike these other models, however, striae provide a readily available, easily obtained, plentiful source of tissue. We believe that striae can and should be used to further our understanding of the mechanical and biochemical factors responsible for the stress remodeling of connective tissue.
