RESUMO
@#Mesenchymal stem cells(MSCs)are multipotent cells with high proliferation ability that can differentiate into a variety of cell types. Thus great plasticity was provided for the regeneration of somatic cells in animal individual growth. Recently, MSCs have been applied to the treatment of traumatic and degenerative diseases on account of its distinct biologic peculiarity. The cells have tremendous potential in the clinical application. This article reviewed clinical treatment of ophthalmic diseases, administration route, methods of acquiring and security about two of MSCs derived from bone marrow and adipose tissue(BMSCs and ADSCs).
RESUMO
Epidermal growth factor (EGF) is a very important peptide growth factor,which is not only involving in a variety of ocular cell mitosis,proliferation and differentiation,but also participates in mediating the signal transduction between cell and cell,cell and matrix interaction and other biological functions.Corneal injury is a common and frequently occurring disease in ophthalmology,and it would lead to blindness without appropriate treatment.Researches showed that EGF can promote the repair and regeneration of wounded cornea.In recent years,these studies advance from animal experiment stage to clinical stage and also from the morphology evaluation stage to the genetics study stage.This paper provided an overview of EGF concept,its biological effectiveness,its relationship to corneal injury and its clinical application.
