Fig. 4.
Photomicrography (left) and immunofluorescence images of cells (right) taken 30 days after the transplantation of the transduced MSC. Note few cells located close, but not attached, to the retina layers (right, H&E staining; magnification 400×). Some shrinking cells may be observed (arrowheads) indicating cell death at that time. At a higher magnification, the immunofluorescence expression of anti-CD90 could be verified on the surface of some cells in selected microscopic fields of the vitreous cavity (anti-CD90, counterstained with DAPI; magnification 630×)
