Inhibition effect of TGF-β2 expression by co-delivery complexes. Rabbits were sacrificed 15 days after filtering surgery. (A) Eye tissues were collected, fixed, dehydrated, and embedded in paraffin. Tissues were cut into 3–4 μm sections for immunohistochemical staining. TGF-β2 was stained as dark brown (circled with red dot lines) for microscopic observation. Quantitative analysis of surgical areas, where the same size tissues were collected and processed with standard Western blot procedures. (B) Western blot bands of TGF-β2 expression (C) quantitative absorbance values of each band and (D) inhibition efficiency of all the testing groups analyzed relative to the normal saline treated group. Scale bar, 200 μm.
