Immunohistochemical Analysis of PDGF-B, in vivo.

Photomicrographs of retinas from various OIR groups that were immunostained for PDGF-B. The expression of PDGF-B was upregulated in the non-treated ischemic and DMSO-treated groups, compared with non-treated normoxic group. While all protein immunoreactivities were downregulated in the YC-1-treated group, compared with DMSO-treated groups. Data are representative of 3 independent experiments. Scale bar: 140 µm.
