Abstract
Tripeptides are physiological products of protein degradation and informational molecules. AED (Ala-Glu-Asp), EDR (Glu-Asp-Arg), EDG (Glu-Asp-Gly) peptides have geroprotective, neuroprotective, reparative and antioxidant properties. The aim of the work is to evaluate the effect of the AED, EDR, EDG peptides on the development of organotypic tissue culture of various genesis in young and old rats. Material and methods. Tissues for organotypic cultivation of mesodermal genesis (testis), ectodermal genesis (cerebral cortex) and entodermalgenesis (bladder) were obtained from young (2-3 months) and old (16-18 months) Wistar rats. Results. AED peptide stimulated cell growth in meso- and endodermal tissues of young and old animals. EDR peptide activated cell proliferation in ecto- and mesodermal tissues of young and old rats. EDG peptide had a stimulating effect on the mesodermal tissue of young rats. Conclusion. Tripeptides, depending on the composition and sequence of their amino acids, have different effects on meso-, ecto- and endodermal genesis tissues obtained from animals of different ages. This indicates the possibility of targeted geroprotective action of AED, EDR, EDG peptides.
