To investigate whether the TGF β1 plasmid DNA carried by lipofectamine could be introduced into cultured rabbit corneal epithelial cells, specific expression of the plasmid pMAM TGF β1 in the cultured corneal epithelial cells was studied. Two days after 12 h of transfection of pMAMTGF β1 mediated by lipofectamine into the cultured corneal epithelial cells, the TGF β1 protein expression specific for pMAMTGF β1 in the cells was detected by means of immunohistochemical staining and the positive rate was 23.37 %. The results suggested that foreign plasmid DNA could be effectively delivered into cultured rabbit corneal epithelial cells by means of lipofectamine, and this will provide a promising method of studying TGF β1 on the mechanism of physiology and pathology concerned with corneal epithelial cells.

The results suggested that foreign plasmid DNA could be substantially delivered into cultured rabbit corneal epithelial cells by means of lipofectamine, and this will provide a promising method of studying TGFβ1 on the mechanism of physiology and pathology concerned with corneal epithelial cells.
