Physiological Stimulus for the Synthesis of Basement Membrane Proteins Leading to Its Reconstruction

Abstract

The aim of the present study was to report the remodeling of the basement membrane through physiological stimulus during the treatment of fibrosis in a lower limb with lymphedema. A clinical trial was conducted involving the evaluation of the basement membrane in skin biopsies before and after treatment for clinical stage II lower limb lymphedema using the Godoy method for the reversal of lymphedema and skin fibrosis. The samples were stained with Gomori’s reticulin stain and evaluated using Weibel’s multipoint morphometric method at the Godoy Clinic. Prior to treatment for lymphedema, rupture and important discontinuity of the basement membrane was found. After treatment, structural continuity and thickness had returned to the regions of previous rupture. The difference was statistically significant (P < 0.05, paired t-test). The present study reports that physiological stimuli targeting the lymphatic system led to the clinical reversal of fibrosis, as well as stimulate the synthesis of extracellular matrix proteins and the reconstruction of the basal lamina of the skin.
