Comparative analysis of the regeneratory potential of blood derivatives on a cell model of corneal epithelium damage

Abstract

The problem of the restoration of the epithelial layer after various modifications of keratoplasty is of great fundamental interest. In this regard, new methods of induction of regeneration are being developed; one of the promising approaches in this area is the use of autologous blood derivatives with a high regenerative potential. Objective: to compare the effect of 3 blood derivatives serum, platelet-rich plasma and plasma rich growth factors on the culture of corneal epithelial cells. The study was carried out on cells of the epithelium of the human cornea of passage 3. To confirm corneal affiliation, cells were typed for characteristic cytokeratins. The dynamics of migration was assessed in the test for wound healing of the monolayer. Proliferation was assessed by the results of the formazan test. Plasma rich growth factors had the greatest stimulating effect on cell proliferation. There were no significant differences between groups in the rate of wound healing of the monolayer. It was found that, in comparison with the control, all stimulants shift the morphological phenotype of cells to a more mature side. As a result of the study, it was shown that all 3 types of tested blood derivatives are promoters of corneal re-epithelialization. The use of drugs obtained from blood can positively influence the processes of epithelialization in persistent epithelial corneal defects, which requires further study.
